The ASAPP Media Group created a niche platform for different stakeholders to come together under the Indian Cement Review umbrella on 23rd April at Hotel Orchid, Mumbai.

THE Indian cement industry today accounts for about seven per cent of the global production and is the second largest cement producer in the world. It has made rapid strides, not only in terms of capacity addition but also in producing world-class quality cement from state-of-the-art technology. The policy paralysis which dragged down the GDP growth from over 8 to under 5 per cent, has led to a crisis in confidence. Further inflation, input costs, high interest costs have compounded the weaknesses, leading to a fall in demand.It is in this context, the ASAPP Media Group created a niche platform for different stakeholders to come together, at the Indian Cement Review’s meet on 23 April at Hotel Orchid, Mumbai.

Delivering the welcome address, Pratap Vijay Padode, Editor in Chief-Infrastructure Today & Managing Director-ASAPP Media Information Group, said, "The cement industry of India, the second largest in the world, has a current capacity of 324 mtpa and operates at 75-80 per cent utilisation. There are 139 large cement plants and over 365 mini cement plants in India, with currently 42 players in the industry.

It is expected to add 30-40 million tonne per annum of capacity in 2013. In India, cement demand emanates from four key segments -housing, accounting for 67 per cent; infrastructure for 13 per cent; commercial construction for 11 per cent and industrial sector for 9 per cent." According to India Ratings & Research, a part of the global ratings agency Fitch, capacity utilisation at cement plants in India fell to 71 per cent in fiscal year 2012-2013 from 89 per cent in 2009-2010, and is expected to be just 75 per cent in 2014-2015, Pratap pointed out. He further sets the ball rolling for the future with his characteristic positive outlook. "I end with the quote that it is darkest before dawn. The worst is over and just as you cannot see the crack of dawn even one hour before it appears and all appears bleak and dark, remember the dawn awaits us."

Delivering the keynote address on the prospects and challenges of the Indian cement industry, NA Viswanathan, Secretary General, Cement Manufacturers’ Association, said that the cement industry has been confronting severe problems on adequate demand, availability of input materials and logistics support, and the three major factors indispensable for a sustainable growth of any industry. He rued the fact that the sharp drop in capacity utilisation has been ironically perceived by the Competition Commission Watchdog as a step towards encouraging cartelisation and has therefore, severely penalised the CMA and a few cement manufacturers for no fault of theirs.

He said though the cement industry has excelled in areas which are within its control, the constraints and limitations of the main infrastructure pillars of support needed, which are mainly in the public sector and under the domain of the government, namely coal, transportation, railways and power; have been severely impacting the growth of the industry.

The current economic slowdown has inevitably left a severe dent on the growth of the cement industry as well. The decline of the industry from an average growth of around 8-9 per cent in the last couple of years to the present low of 5 per cent has shown no sign of improvement in capacity utilisation, which is still a major cause of concern. More specifically, although the Government of India has recently moved ahead with reforms needed to arrest the down-trend in the economy, what is today needed is the timely execution of the policies with adequate funding with regard to infrastructure sectors like housing, irrigation, roads, and ports, airports, for the sustained and inclusive growth of the economy, according to Viswanathan. He also said that the Working Group on Cement Industry for XII Plan in its Report submitted to the Planning Commission, had made a host of recommendations to various Departments/Ministries for the revival of the growth of the cement industry after critically examining the whole gamut of the concerned issues.

The conference gathered in experts from various knowledge domains to deliberate on myriad topics: Srinivasan Raman, Head-Technical Services, Essar Oil, spoke on the use of alternate fuel, especially the importance of petcoke as an alternate fuel, while Navin Bhagawati, Managing Director, Bhagawati Associates, shared his decades-long experience on setting up greenfield projects, Ajay Hans, Managing Director, Petron Engineering, provided an insight into efficient project management leading to a high success rate of project completed on time. Ganesh Kamat, Technical Adviser, Ganaka Engineers Architects, emphasised the importance of green and sustainable construction technology; Anuj Maheshwari, Technical Head – RMC, Ultratech, detailed the emerging trends in the use of RMC and how a progressive shift from prescriptive use of concr¡ete to performance and application-based use can bring greater sustainable construction and Gautam Mukund Padukone, Design Head – EPC, L&T Construction, spoke about the development and use of environmental friendly binders, especially energetically modified cement. Rajive Mehta, Chairman, Committee on Railway Matters, CMA and Executive Vice president (logistics), UltraTech, focused on the importance of cement terminals to facilitate use of bulk cement and Capt Yogesh Kundra, Deputy Executive Director-Supply Chain, Dalmia Cement, specifically focused on the new trends to optimise the cost of logistics. The CEO Round Table summed up the proceeding with major emphasis on the need to come onto one platform and discuss and find solutions to pressing issues like spiralling cost, the logistical and other related issues.

KK Taparia, Chief Executive Officer & Adviser, Murali Cement, Mahesh Mudda, Executive Director & Chief Executive Officer, New Consolidated Construction Co and Jacques Van Niekerk, Head-Supply Chain Ambuja Cement, shed light on various aspects of the industry and stressed what needed to be done on a war footing. "Once we have an approach of partnering, understanding each other’s needs and requirements, and the issues faced, rather than getting into legal battles, I think the road ahead will be smoother. Whether it is issues of cartelisation or fluctuating prices, it is better that we sit together and sort out the differences and fight together, even if it is the government we have to fight, for the healthy growth of the industry," said Mudda.

Van Niekerk supported the view, saying, "We need strong partnerships, and we need a strong political will to effect the change that we are looking, not only for the industry but for the entire nation, which deserves the change." According to him, what customers in the future will be demanding from the industry, will be increasingly complicated products, more complicated solutions to cater to their specific needs and requirements. "Cement manufacturers will need to come out with tailor-made solutions pertaining to the specific needs of the customer that calls for more capital and a shift in the thinking.” He added, "From the supply chain perspective, I think customers in India deserve a service level substantially better than what is being offered to them today. Instead of looking at the supply chain as a cost-centre, it should be viewed as a generator of values and that could add the topline."

Taparia stressed on the importance of price stabilisation for the cement industry to grow. He said, "The supply demand stabilisation is one of the important areas that the cement industry needs to look into. Instead of taking unilateral decisions, it is imperative to have a collaborative approach on how to bring about price stability."

Efficient Oil Cooling for Gearbox in the Cement Industry. How a High-Performance Plate Heat Exchanger Ensured Thermal Stability and Operational Continuity.

Contributed by: Narendra Joshi and Sourabh Mishra

Application: Gearbox Oil Cooling
Objective: To maintain optimal oil temperature in high-viscosity lubrication systems for gearboxes in cement plants, ensuring uninterrupted operations and minimizing production losses due
to overheating.
Challenge: A prominent cement manufacturing company’s conventional cooling systems were failing to maintain the oil temperature within the optimal range, jeopardizing equipment performance and leading to avoidable downtime.

Background with the Existing System
In heavy-duty industrial applications, particularly in the cement industry, gearboxes are critical components that must operate under high mechanical loads and harsh conditions. These gearboxes rely on lubrication systems where oil plays a dual role, lubrication and heat dissipation. A recurring challenge in such setups is managing the temperature of the gearbox oil. When oil heats beyond a critical limit, its viscosity drops, reducing its ability to form a protective film. This leads to increased friction between components, heat generation, and eventual damage to gearbox components — directly impacting plant uptime and production output.

Delivering Sustainable Heat Transfer Solution with HRS FUNKE High Efficiency Heat Exchanger
This system was selected for its:

  • Excellent thermal performance, ensuring rapid and efficient oil cooling even with high-viscosity fluids.
  • Leakage-proof operation, with no cross-contamination between cooling water and lubrication oil.
  • Robust design, capable of withstanding high operating pressures and variable flow conditions.

The plate exchanger was custom configured based on the oil’s properties, desired outlet temperature, and ambient heat load, ensuring that the oil remained within the specified viscosity range necessary for maintaining gearbox operation and lubrication integrity.

Performance Benefits Delivered

  • Oil temperature control and maintained consistently within target range
  • Viscosity stability and prevented breakdown of lubrication film
  • Equipment reliability and reduced risk of gearbox overheating or failure
  • Production continuity and eliminated unplanned stoppages
  • Long-Term savings and lower maintenance costs and extended oil life

Solution: To address the problem, HRS Process Systems Ltd recommended the installation of a Funke Plate Heat Exchanger a compact, high-efficiency thermal solution engineered specifically for industrial lubrication oil cooling.

Conclusion: The customer achieved precision oil temperature control, ensuring that the gearboxes operated at optimal conditions. This not only safeguarded the mechanical integrity of the gearbox but also directly contributed to higher plant uptime and improved production efficiency in heavy industries like cement manufacturing.

How Upgrades Can Deliver Energy Savings Across the Cement Process

Published

Jacob Brinch-Nielsen, Vice President of Professional Services, FLSmidth Cement, brings together recommendations from experts across the flow sheet to demonstrate the role of upgrades in optimising the cement manufacturing process.

Improving energy efficiency in material transport
Pneumatic conveying offers a cleaner and more contained alternative to mechanical conveying. However, pneumatic systems can also be energy-intensive, with inefficiencies arising from air leakage, pressure losses, and outdated equipment designs. Optimising these systems can significantly reduce energy consumption and operating costs.
“One major challenge is maintaining efficient air-to-material ratios, as excessive air use leads to unnecessary power consumption,” explains Emilio Vreca, Manager of PT Product Engineering “Leaks in piping and inefficient compressors further compound energy losses. To address these issues, upgrading to the latest pneumatic conveying solutions can yield substantial improvements.”
The latest pump design—the Fuller-Kinyon® (FK) ‘N’ Pump—provides power savings of up to 15 per cent thanks to an improved seal, while an extended barrel and screw design have improved volumetric efficiency by more than 15 per cent. Similarly, the latest generation Ful-Vane™ Air Compressor has been engineered for increased energy efficiency, with an improved inlet area for capturing larger air flows and compatibility with variable frequency drives.

Optimising energy efficiency in packing and dispatch
Even minor inefficiencies in bagging and palletising can lead to higher maintenance demands, increased material waste, and unnecessary energy use. Reducing these inefficiencies is yet another lever to improve overall plant performance and sustainability.
Upgrading rotary packers enhances weighing accuracy, reduces spout-to-spout variations, and lowers reject rates, improving both product consistency and energy efficiency. Similarly, replacing pneumatic drive systems in palletisers with electric alternatives eliminates compressed air dependency, leading to more precise bag handling and reduced energy demand. These targeted upgrades help streamline operations while minimising environmental impact.
A key development in dust control is the FILLPro™ Dust Reduction Kit for GIROMAT® EVO. “By refining material flow and fluidisation, FILLPro reduces dust emissions at the source, improving bagging efficiency and plant cleanliness,” explains Gabriele Rapizza, Proposal Engineer. “This reduces material loss, prevents blockages, and cuts down on maintenance, helping plants achieve a more stable and energy-efficient packing operation.”

How services contribute to increased energy efficiency
In the past, many viewed the role of the supplier as a “sell-and-move-on” model. Things have certainly changed. As cement producers face challenging markets, heightened competition, and increasingly ambitious decarbonisation targets there is little room to tolerate inefficiencies within the plant. The paradigm has shifted such that the value of expert services is as essential as the initial equipment supplied. Furthermore, as digital solutions progress at speed, a fluid, long-term partnership gives cement plants the best platform to take advantage of the latest tools.
Whether it’s an audit to identify why energy efficiency has decreased from one year to the next, or even an optimisation package preparing your plant for carbon capture solutions – we are believers in the principle that there is always more we can do to improve efficiency. For example, our Online Condition Monitoring Services (OCMS) provide continuous monitoring of critical equipment such as the kiln, mills, cooler and fans, aggregating data and utilising advanced algorithms to identify potential trouble spots. As the OEM and an experienced full solutions provider, we can support these services with expert advice, not only alerting you to a problem but also providing recommendations as to how to remedy it or attending site to support you in person.

Small upgrades, big impact
Energy efficiency is a critical factor, influencing both operational costs and sustainability goals. While large-scale innovations such as carbon capture will play an essential role in long-term decarbonisation (and steal the headlines), incremental mechanical upgrades offer an immediate pathway to lower energy consumption with minimal disruption.
By optimising key process areas — grinding, dosing, combustion, cooling, and material transport — you can achieve measurable energy savings while improving performance and flexibility. These solutions provide a strong return on investment and pave the way for a more sustainable cement industry.
