Poonam Sharma, HR Director, Heidelberg Cement India Ltd. and Zuari Cement Ltd., sheds light on the human resource factor in the cement industry, given its labour-intensive nature and safety protocol.
Cement industry being labor intensive industry where physical presence of the manpower is required especially at production sites. How were you able to manage the availability of manpower during the COVID times?
As per the government norms and covid restrictions, initially we allowed only one-third of the total workforce in the workplace, gradually increasing it to about fifty percent as restrictions eased up. Eventually when all covid related restrictions were lifted, plants worked with full manpower capacity following the safety measures like wearing masks, making sure that social distancing was observed by the workforce and moving to contact-less attendance system. There were regular temperature checks at the workplace and we regularly sanitised the workplace and supplied oxygen cylinders to the hospitals in our colonies. The Organisation tried to provide as much support as possible to our employees and their families which helped seamless operations at the plant and our production output remain unhindered.
With the easing of COVID outbreak and economies coming back to normal, is there any change of strategies in terms of driving a positive work environment?
We were allowed to work from home for almost a year. This was a new way of working bringing in a realisation that much was possible in the new connected virtual world. Many of us became more skilled in the IT world.
As employees got back to the office, we continued to take covid prevention measures. If there was anyone who was Covid positive or had a family member who was Covid positive, we allowed them paid leave. This rule applied to all employees including workmen. We created a quarantine facility for our workmen as well.
Post the pandemic, there was a sudden spurt in hiring from all around in the industry. We observed that retaining talent became a big issue for the organisation and hence we started looking at avenues for employee retention. To begin with, our efforts focused on providing enhanced opportunities for employees to grow and learn. Although the Organisation always promoted internal talent, we formally launched an internal job portal, giving maximum opportunities to our in-house talent while promoting them to the available vacancies. The capacity expansion and sudden transformations in the Indian cement sector created multifold opportunities for talent movement across the industry. It is likely that much exchange of workforce will happen through the pull and push within the sector, with employees moving to greener pastures as any given opportunity. We have also been endeavoring to provide learning opportunities and hiring fresh talent from the campuses as well as laterally as a reinforcement strategy. We have not been hiring externally for the key positions, preferring to fill them with people from within the organisation.
Another initiative that we took was introducing special sales incentives and reward programs in order to keep our field- force motivated and reward the performers.
Initially we used to have career planning and succession planning only for the senior most people. We now have gone down one level, creating a healthy pipeline for talent in place and in our pursuit to create a positive and motivating work environment.
Once the lockdown restrictions were removed, were there any challenges in bringing back the workforce to office? How do you feel the attrition rates have changed post COVID?
As mentioned earlier, the opening of offices was a sigh of relief for many of our employees as it was a sign that the world would finally return to normal, and we would regain our freedom to socialise without fear after all. Those who were afraid of technology, found themselves discovering how they could achieve far more, connect to a larger section of teams, save the traffic snarls and time taken to reach office and still get the work done efficiently. Many Organisations moved to a permanent WFH policy or the hybrid model, considering the benefits like cost saving without losing quality and productivity.
However, there was also a realisation that the office doubled up as our social circle was healthier with in-person meetings now replacing the grueling onscreen time. Also, most people felt that they were working longer hours with more screen time when they were working from home and there was a pressure of always being online. Also, there is always that sense of being alone when one is working from home, while in the workplace there is interaction and a sense of normalcy.
While returning to office physically meant more time in traffic and other commuting issues, considering the other benefits, employees welcomed the decision of the organisation to open the offices and there was not much of an effort getting back willing people to office.
Dealing with huge manpower, there are labour unions at the production level. How do you deal with these challenges like labour disputes and violations?
Cement is a labor-intensive industry. We have unions in all the plants. We have installed monitoring systems and access control for all those who enter our units, be it our employees, contract labour or visitors. We do have to make efforts to maintain a harmonious environment in the plant; however, we have been able to maintain peace almost always, we believe in preventive maintenance rather than breakdowns and especially in employee relations than Industrial relations. Towards adding value to our employees, we have been organising shop floor trainings for Wage board and contract workmen. Last year, we introduced a pilot program for our workmen where we took them out to an offsite venue for conducting behavioral training which was very well appreciated by the workmen. Hence, considering the good response we have now been planning more such interventions for workmen for motivation and skill upgradation.
We have our quarterly town hall address by our Managing Director for both staff and workmen. It helps them understand the direction in which the business is headed, the issues that the business is facing which is followed by an open house where they can ask questions directly to the Managing Director. This gives them a sense of inclusion and makes them understand the areas in which we need their support. As of now, our workmen are very supportive, and we do not have any major issues/disruptions.
With Automation and robotics being on the rise, how do you feel it would affect the workforce in the cement industry? As of now cement is a very conventional industry where the shop floor is concerned and it is slowly getting completely automated, and we have the CCR machinery, which allows computer monitoring and controls to some extent. There are certain areas where the operations are to a large extent computer controlled and operated, especially the data collection and updates, but the industry at large, is still manual and labour intensive. Therefore, hopefully the automation will help make the job of our human resources more productive and error free and slowly the dependence on manpower may get reduced.
While we are looking to expand our capacities and productivity and make our organisation more cost effective, there have been some reductions in manpower where needed. We have also brought in some systemic controls for our contract labour as I mentioned earlier. There are many automation projects going on in the Company, which we hope will bring in more efficiency and enhance productivity.
As mentioned by you, that the senior positions of those retiring from the organisation are being filled by the next in line hierarchy and new talent in senior positions is not being hired, does that mean that the average age of the organisation is reducing?
Yes, the average age in the last 10 years has gone down a good five years. This had been done through concerted efforts to replace the outgoing employees with younger candidates. Apart from that, we are hiring from campuses and getting young talent in the workplace, further reducing the average age.
We had observed in the past that this young talent, especially from the campuses, left sooner than expected. In recent years, however, our retention has been much better. We have a good no. of management trainees in the sales team and graduate engineer trainees in the plants and customer services hired from premier institutes.
We are sure that this will energise the workforce and bring in fresh perspectives in the way of doing business. Our aim is to balance the invaluable experience already existing in the company with young energy.
What are the dynamic policies that are there in your organisation to ensure the safety of your employees and labour?
As a principle, we have a very strong safety policy from the Heidelberg Group in Germany. We cater to very high standards of safety and ensure continual sharing of the same through e-mailers and training.
Some awards have been constituted to promote safety at ground level such as the Golden Helmet award in the organisation that goes to any person who maintains and observes the most safety measures or implements something radical to increase the safety standards of the organisation. Some employees of the month awards have also been given to employees who have shown exemplary conduct towards safety.
It has been heartening to see women workmen also wearing the Golden Helmet. They treat it like a crown, as a symbol of pride and honour that they have earned in the organisation, thus, keeping them motivated to keep taking steps in the direction of safety.
On one hand we are rewarding safety, on the other hand we are also penalising people for violations even to the level of termination if they have a safety violation history. We also have a lot of training programs on safety as a reminder to every employee and contact worker of the organisation that safety is of the utmost importance in the workplace.
Is there any role of Heidelberg Cement Group in the HR policies of Heidelberg Cement India?
Policies are a mix of both, the group policies, and the local ones. The basic tenets of the policies on an organisation level remains standard, like harnessing, safely operating electrical equipment etc. Safety training and norms are observed and policies regarding the same are very stringent from the group level as well as the local level. There is a lot of support from group level for implementing and standardising policies, but also local conditions are kept in mind while formulating policies.
Working in the core sector, how do you promote diversity while hiring employees for your organisation?
Cement industry is very labour intensive. In our corporate office we have some diversity. However, in the plants and sales offices, we find it difficult to attract women. Our endeavour has been to stay neutral and hire on merit and do our best to create an environment for comfortable working for women candidates.
Most women who work in the organisation are given an even playing field, and being a woman myself, I strongly feel that women are not weak in any sense of the way. All we need to do is not discriminate against them based on gender and support them fulfilling their family responsibilities. We have hired women in the sales and the plants as well. Unfortunately, the labour jobs are very labour oriented and there is a lot of physical strain involved. So even though we have been attempting to hire diversity candidates, the plant’s retention has been an issue. We will continue to take steps in this direction going forward.

Refractory demands in our kiln have changed

Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, points out why performance, predictability and life-cycle value now matter more than routine replacement in cement kilns.
As Indian cement plants push for higher throughput, increased alternative fuel usage and tighter shutdown cycles, refractory performance in kilns and pyro-processing systems is under growing pressure. In this interview, Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, shares how refractory demands have evolved on the ground and how smarter digital monitoring is improving kiln stability, uptime and clinker quality.
How have refractory demands changed in your kiln and pyro-processing line over the last five years?
Over the last five years, refractory demands in our kiln and pyro line have changed. Earlier, the focus was mostly on standard grades and routine shutdown-based replacement. But now, because of higher production loads, more alternative fuels and raw materials (AFR) usage and greater temperature variation, the expectation from refractory has increased.
In our own case, the current kiln refractory has already completed around 1.5 years, which itself shows how much more we now rely on materials that can handle thermal shock, alkali attack and coating fluctuations. We have moved towards more stable, high-performance linings so that we don’t have to enter the kiln frequently for repairs.
Overall, the shift has been from just ‘installation and run’ to selecting refractories that give longer life, better coating behaviour and more predictable performance under tougher operating conditions.
What are the biggest refractory challenges in the preheater, calciner and cooler zones?
• Preheater: Coating instability, chloride/sulphur cycles and brick erosion.
• Calciner: AFR firing, thermal shock and alkali infiltration.
• Cooler: Severe abrasion, red-river formation and mechanical stress on linings.
Overall, the biggest challenge is maintaining lining stability under highly variable operating conditions.
How do you evaluate and select refractory partners for long-term performance?
In real plant conditions, we don’t select a refractory partner just by looking at price. First, we see their past performance in similar kilns and whether their material has actually survived our operating conditions. We also check how strong their technical support is during shutdowns, because installation quality matters as much as the material itself.
Another key point is how quickly they respond during breakdowns or hot spots. A good partner should be available on short notice. We also look at their failure analysis capability, whether they can explain why a lining failed and suggest improvements.
On top of this, we review the life they delivered in the last few campaigns, their supply reliability and their willingness to offer plant-specific custom solutions instead of generic grades. Only a partner who supports us throughout the life cycle, which includes selection, installation, monitoring and post-failure analysis, fits our long-term requirement.
Can you share a recent example where better refractory selection improved uptime or clinker quality?
Recently, we upgraded to a high-abrasion basic brick at the kiln outlet. Earlier we had frequent chipping and coating loss. With the new lining, thermal stability improved and the coating became much more stable. As a result, our shutdown interval increased and clinker quality remained more consistent. It had a direct impact on our uptime.
How is increased AFR use affecting refractory behaviour?
Increased AFR use is definitely putting more stress on the refractory. The biggest issue we see daily is the rise in chlorine, alkalis and volatiles, which directly attack the lining, especially in the calciner and kiln inlet. AFR firing is also not as stable as conventional fuel, so we face frequent temperature fluctuations, which cause more thermal shock and small cracks in the lining.
Another real problem is coating instability. Some days the coating builds too fast, other days it suddenly drops, and both conditions impact refractory life. We also notice more dust circulation and buildup inside the calciner whenever the AFR mix changes, which again increases erosion.
Because of these practical issues, we have started relying more on alkali-resistant, low-porosity and better thermal shock–resistant materials to handle the additional stress coming from AFR.
What role does digital monitoring or thermal profiling play in your refractory strategy?
Digital tools like kiln shell scanners, IR imaging and thermal profiling help us detect weakening areas much earlier. This reduces unplanned shutdowns, helps identify hotspots accurately and allows us to replace only the critical sections. Overall, our maintenance has shifted from reactive to predictive, improving lining life significantly.
How do you balance cost, durability and installation speed during refractory shutdowns?
We focus on three points:
• Material quality that suits our thermal profile and chemistry.
• Installation speed, in fast turnarounds, we prefer monolithic.
• Life-cycle cost—the cheapest material is not the most economical. We look at durability, future downtime and total cost of ownership.
This balance ensures reliable performance without unnecessary expenditure.
What refractory or pyro-processing innovations could transform Indian cement operations?
Some promising developments include:
• High-performance, low-porosity and nano-bonded refractories
• Precast modular linings to drastically reduce shutdown time
• AI-driven kiln thermal analytics
• Advanced coating management solutions
• More AFR-compatible refractory mixes
These innovations can significantly improve kiln stability, efficiency and maintenance planning across the industry.

MSR Kali Prasad, Chief Digital and Information Officer, Shree Cement, discusses how data, discipline and scale are turning Industry 4.0 into everyday business reality.
Over the past five years, digitalisation in Indian cement manufacturing has moved decisively beyond experimentation. Today, it is a strategic lever for cost control, operational resilience and sustainability. In this interview, MSR Kali Prasad, Chief Digital and Information Officer, Shree Cement, explains how integrated digital foundations, advanced analytics and real-time visibility are helping deliver measurable business outcomes.
How has digitalisation moved from pilot projects to core strategy in Indian cement manufacturing over the past five years?
Digitalisation in Indian cement has evolved from isolated pilot initiatives into a core business strategy because outcomes are now measurable, repeatable and scalable. The key shift has been the move away from standalone solutions toward an integrated digital foundation built on standardised processes, governed data and enterprise platforms that can be deployed consistently across plants and functions.
At Shree Cement, this transition has been very pragmatic. The early phase focused on visibility through dashboards, reporting, and digitisation of critical workflows. Over time, this has progressed into enterprise-level analytics and decision support across manufacturing and the supply chain,
with clear outcomes in cost optimisation, margin protection and revenue improvement through enhanced customer experience.
Equally important, digital is no longer the responsibility of a single function. It is embedded into day-to-day operations across planning, production, maintenance, despatch and customer servicing, supported by enterprise systems, Industrial Internet of Things (IIoT) data platforms, and a structured approach to change management.
Which digital interventions are delivering the highest ROI across mining, production and logistics today?
In a capital- and cost-intensive sector like cement, the highest returns come from digital interventions that directly reduce unit costs or unlock latent capacity without significant capex.
Supply chain and planning (advanced analytics): Tools for demand forecasting, S&OP, network optimisation and scheduling deliver strong returns by lowering logistics costs, improving service levels, and aligning production with demand in a fragmented and regionally diverse market.
Mining (fleet and productivity analytics): Data-led mine planning, fleet analytics, despatch discipline, and idle-time reduction improve fuel efficiency and equipment utilisation, generating meaningful savings in a cost-heavy operation.
Manufacturing (APC and process analytics): Advanced Process Control, mill optimisation, and variability reduction improve thermal and electrical efficiency, stabilise quality and reduce rework and unplanned stoppages.
Customer experience and revenue enablement (digital platforms): Dealer and retailer apps, order visibility and digitally enabled technical services improve ease of doing business and responsiveness. We are also empowering channel partners with transparent, real-time information on schemes, including eligibility, utilisation status and actionable recommendations, which improves channel satisfaction and market execution while supporting revenue growth.
Overall, while Artificial Intelligence (AI) and IIoT are powerful enablers, it is advanced analytics anchored in strong processes that typically delivers the fastest and most reliable ROI.
How is real-time data helping plants shift from reactive maintenance to predictive and prescriptive operations?
Real-time and near real-time data is driving a more proactive and disciplined maintenance culture, beginning with visibility and progressively moving toward prediction and prescription.
At Shree Cement, we have implemented a robust SAP Plant Maintenance framework to standardise maintenance workflows. This is complemented by IIoT-driven condition monitoring, ensuring consistent capture of equipment health indicators such as vibration, temperature, load, operating patterns and alarms.
Real-time visibility enables early detection of abnormal conditions, allowing teams to intervene before failures occur. As data quality improves and failure histories become structured, predictive models can anticipate likely failure modes and recommend timely interventions, improving MTBF and reducing downtime. Over time, these insights will evolve into prescriptive actions, including spares readiness, maintenance scheduling, and operating parameter adjustments, enabling reliability optimisation with minimal disruption.
A critical success factor is adoption. Predictive insights deliver value only when they are embedded into daily workflows, roles and accountability structures. Without this, they remain insights without action.
In a cost-sensitive market like India, how do cement companies balance digital investment with price competitiveness?
In India’s intensely competitive cement market, digital investments must be tightly linked to tangible business outcomes, particularly cost reduction, service improvement, and faster decision-making.
This balance is achieved by prioritising high-impact use cases such as planning efficiency, logistics optimisation, asset reliability, and process stability, all of which typically deliver quick payback. Equally important is building scalable and governed digital foundations that reduce the marginal cost of rolling out new use cases across plants.
Digitally enabled order management, live despatch visibility, and channel partner platforms also improve customer centricity while controlling cost-to-serve, allowing service levels to improve without proportionate increases in headcount or overheads.
In essence, the most effective digital investments do not add cost. They protect margins by reducing variability, improving planning accuracy, and strengthening execution discipline.
How is digitalisation enabling measurable reductions in energy consumption, emissions, and overall carbon footprint?
Digitalisation plays a pivotal role in improving energy efficiency, reducing emissions and lowering overall carbon intensity.
Real-time monitoring and analytics enable near real-time tracking of energy consumption and critical operating parameters, allowing inefficiencies to be identified quickly and corrective actions to be implemented. Centralised data consolidation across plants enables benchmarking, accelerates best-practice adoption, and drives consistent improvements in energy performance.
Improved asset reliability through predictive maintenance reduces unplanned downtime and process instability, directly lowering energy losses. Digital platforms also support more effective planning and control of renewable energy sources and waste heat recovery systems, reducing dependence on fossil fuels.
Most importantly, digitalisation enables sustainability progress to be tracked with greater accuracy and consistency, supporting long-term ESG commitments.
What role does digital supply chain visibility play in managing demand volatility and regional market dynamics in India?
Digital supply chain visibility is critical in India, where demand is highly regional, seasonality is pronounced, and logistics constraints can shift rapidly.
At Shree Cement, planning operates across multiple horizons. Annual planning focuses on capacity, network footprint and medium-term demand. Monthly S&OP aligns demand, production and logistics, while daily scheduling drives execution-level decisions on despatch, sourcing and prioritisation.
As digital maturity increases, this structure is being augmented by central command-and-control capabilities that manage exceptions such as plant constraints, demand spikes, route disruptions and order prioritisation. Planning is also shifting from aggregated averages to granular, cost-to-serve and exception-based decision-making, improving responsiveness, lowering logistics costs and strengthening service reliability.
How prepared is the current workforce for Industry 4.0, and what reskilling strategies are proving most effective?
Workforce preparedness for Industry 4.0 is improving, though the primary challenge lies in scaling capabilities consistently across diverse roles.
The most effective approach is to define capability requirements by role and tailor enablement accordingly. Senior leadership focuses on digital literacy for governance, investment prioritisation, and value tracking. Middle management is enabled to use analytics for execution discipline and adoption. Frontline sales and service teams benefit from
mobile-first tools and KPI-driven workflows, while shop-floor and plant teams focus on data-driven operations, APC usage, maintenance discipline, safety and quality routines.
Personalised, role-based learning paths, supported by on-ground champions and a clear articulation of practical benefits, drive adoption far more effectively than generic training programmes.
Which emerging digital technologies will fundamentally reshape cement manufacturing in the next decade?
AI and GenAI are expected to have the most significant impact, particularly when combined with connected operations and disciplined processes.
Key technologies likely to reshape the sector include GenAI and agentic AI for faster root-cause analysis, knowledge access, and standardisation of best practices; industrial foundation models that learn patterns across large sensor datasets; digital twins that allow simulation of process changes before implementation; and increasingly autonomous control systems that integrate sensors, AI, and APC to maintain stability with minimal manual intervention.
Over time, this will enable more centralised monitoring and management of plant operations, supported by strong processes, training and capability-building.

Professor Procyon Mukherjee discusses how as the cement industry accelerates its shift towards digitalisation, data-driven technologies are becoming the mainstay of sustainability and control across the value chain.
The cement industry, long perceived as traditional and resistant to change, is undergoing a profound transformation driven by digital technologies. As global infrastructure demand grows alongside increasing pressure to decarbonise and improve productivity, cement manufacturers are adopting data-centric tools to enhance performance across the value chain. Nowhere is this shift more impactful than in grinding, which is the energy-intensive final stage of cement production, and in the materials that make grinding more efficient: grinding media and grinding aids.
The imperative for digitalisation
Cement production accounts for roughly 7 per cent to 8 per cent of global CO2 emissions, largely due to the energy intensity of clinker production and grinding processes. Digital solutions, such as AI-driven process controls and digital twins, are helping plants improve stability, cut fuel use and reduce emissions while maintaining consistent product quality. In one deployment alongside ABB’s process controls at a Heidelberg plant in Czechia, AI tools cut fuel use by 4 per cent and emissions by 2 per cent, while also improving operational stability.
Digitalisation in cement manufacturing encompasses a suite of technologies, broadly termed as Industrial Internet of Things (IIoT), AI and machine learning, predictive analytics, cloud-based platforms, advanced process control and digital twins, each playing a role in optimising various stages of production from quarrying to despatch.
Grinding: The crucible of efficiency and cost
Of all the stages in cement production, grinding is among the most energy-intensive, historically consuming large amounts of electricity and representing a significant portion of plant operating costs. As a result, optimising grinding operations has become central to digital transformation strategies.
Modern digital systems are transforming grinding mills from mechanical workhorses into intelligent, interconnected assets. Sensors throughout the mill measure parameters such as mill load, vibration, mill speed, particle size distribution, and power consumption. This real-time data, fed into machine learning and advanced process control (APC) systems, can dynamically adjust operating conditions to maintain optimal throughput and energy usage.
For example, advanced grinding systems now predict inefficient conditions, such as impending mill overload, by continuously analysing acoustic and vibration signatures. The system can then proactively adjust clinker feed rates and grinding media distribution to sustain optimal conditions, reducing energy consumption and improving consistency.
Digital twins: Seeing grinding in the virtual world
One of the most transformative digital tools applied in cement grinding is the digital twin, which a real-time virtual replica of physical equipment and processes. By integrating sensor data and
process models, digital twins enable engineers to simulate process variations and run ‘what-if’
scenarios without disrupting actual production. These simulations support decisions on variables such as grinding media charge, mill speed and classifier settings, allowing optimisation of energy use and product fineness.
Digital twins have been used to optimise kilns and grinding circuits in plants worldwide, reducing unplanned downtime and allowing predictive maintenance to extend the life of expensive grinding assets.
Grinding media and grinding aids in a digital era
While digital technologies improve control and prediction, materials science innovations in grinding media and grinding aids have become equally crucial for achieving performance gains.
Grinding media, which comprise the balls or cylinders inside mills, directly influence the efficiency of clinker comminution. Traditionally composed of high-chrome cast iron or forged steel, grinding media account for nearly a quarter of global grinding media consumption by application, with efficiency improvements translating directly to lower energy intensity.
Recent advancements include ceramic and hybrid media that combine hardness and toughness to reduce wear and energy losses. For example, manufacturers such as Sanxin New Materials in China and Tosoh Corporation in Japan have developed sub-nano and zirconia media with exceptional wear resistance. Other innovations include smart media embedded with sensors to monitor wear, temperature, and impact forces in real time, enabling predictive maintenance and optimal media replacement scheduling. These digitally-enabled media solutions can increase grinding efficiency by as much as 15 per cent.
Complementing grinding media are grinding aids, which are chemical additives that improve mill throughput and reduce energy consumption by altering the surface properties of particles, trapping air, and preventing re-agglomeration. Technology leaders like SIKA AG and GCP Applied Technologies have invested in tailored grinding aids compatible with AI-driven dosing platforms that automatically adjust additive concentrations based on real-time mill conditions. Trials in South America reported throughput improvements nearing 19 per cent when integrating such digital assistive dosing with process control systems.
The integration of grinding media data and digital dosing of grinding aids moves the mill closer to a self-optimising system, where AI not only predicts media wear or energy losses but prescribes optimal interventions through automated dosing and operational adjustments.
Global case studies in digital adoption
Several cement companies around the world exemplify digital transformation in practice.
Heidelberg Materials has deployed digital twin technologies across global plants, achieving up to 15 per cent increases in production efficiency and 20 per cent reductions in energy consumption by leveraging real-time analytics and predictive algorithms.
Holcim’s Siggenthal plant in Switzerland piloted AI controllers that autonomously adjusted kiln operations, boosting throughput while reducing specific energy consumption and emissions.
Cemex, through its AI and predictive maintenance initiatives, improved kiln availability and reduced maintenance costs by predicting failures before they occurred. Global efforts also include AI process optimisation initiatives to reduce energy consumption and environmental impact.
Challenges and the road ahead
Despite these advances, digitalisation in cement grinding faces challenges. Legacy equipment may lack sensor readiness, requiring retrofits and edge-cloud connectivity upgrades. Data governance and integration across plants and systems remains a barrier for many mid-tier producers. Yet, digital transformation statistics show momentum: more than half of cement companies have implemented IoT sensors for equipment monitoring, and digital twin adoption is growing rapidly as part of broader Industry 4.0 strategies.
Furthermore, as digital systems mature, they increasingly support sustainability goals: reduced energy use, optimised media consumption and lower greenhouse gas emissions. By embedding intelligence into grinding circuits and material inputs like grinding aids, cement manufacturers can strike a balance between efficiency and environmental stewardship.
Conclusion
Digitalisation is not merely an add-on to cement manufacturing. It is reshaping the competitive and sustainability landscape of an industry often perceived as inertia-bound. With grinding representing a nexus of energy intensity and cost, digital technologies from sensor networks and predictive analytics to digital twins offer new levers of control. When paired with innovations in grinding media and grinding aids, particularly those with embedded digital capabilities, plants can achieve unprecedented gains in efficiency, predictability and performance.
For global cement producers aiming to reduce costs and carbon footprints simultaneously, the future belongs to those who harness digital intelligence not just to monitor operations, but to optimise and evolve them continuously.
