The earnings projections of cement companies for FY18 are likely to suffer amid lower antic-ipated sales volumes and subdued prices. According to dealer estimates, the all-India average cement price fell by 2 per cent sequentially to Rs 326 per 50 kg bag in the December 2017 quarter. On a year-on-year basis, it rose marginally by 5 per cent. Historically, the sector has been reporting better traction in December. However, this time, realisation is under pressure due to several headwinds.
For instance, cost of sand, a key raw material, has increased by 4-5 times from the year ago due to lesser availability. In addition, construction activities in the real estate segment have slowed following demonetisation and implementation of Real Estate Regulatory Authority (RERA) Bill. The segment accounts for 60-65 per cent of total cement consumption. This has impacted offtake volume.
According to analysts, meeting the earlier expectation of 7-8 per cent volume growth for the full year will be a difficult task. To deliver that much growth, companies would require to clock 9 per cent growth in the second half of the fiscal.
Pet coke duty hike to hit operating margins
Cement companies operating profits may fall by one per cent following the Government’s decision to hike import duty on pet coke to 10 percent from the current 2.5 percent, a report said. ‘The operating margins of cement companies, which use high proportion of pet coke are likely to be affected following the government’s decision to increase the import duty on pet coke to 10 per cent from the present 2.5 per cent. The operating margins of cement manufacturers may fall by about 1 per cent, if increased cost is not passed on to end users,’ India Ratings said in its report.
The increase in import duty was announced after the Supreme Court decided to lift the ban on the use of pet coke. The Supreme Court allowed the cement industry to use pet coke as a feedstock, which had been banned last month to clean up the air pollution. While, issuing the exemption order for cement units, the apex court asked the government to frame guidelines for the use of pet coke.
Ind-Ra said that the cement manufacturers may resort to coal imports due to low domestic availability. Cement manufacturers prefer using pet coke, as it contains high calorific value (7,500-8, 500 Kcal/kg), to non-coking coal (2,200-7,000 Kcal/kg). The rise in the import duty on pet coke will result in a rise in power and fuel cost per metric tonne to Rs 5-7 per bag.
Total pet coke consumption in India increased by 34 per cent in October 2017 to 2 million metric tonne as compared with the level recorded for October 2015. Of the total pet coke consumed in the country during FY17-1HFY18, about 50 per cent was sourced domestically and the remaining through imports. According to Ind-Ra’s assessment, 35 per cent of the total pet coke imports were consumed by the cement industry.
Cement prices set to increase
Cement prices in India are expected to increase by Rs 3-4/bag by mid-January as the government has decided to hike the import duty on pet coke from the current 2.5 to 10 per cent. The rise in duty is expected to increase production costs by Rs 50-60/t and sector analysts predict the increase will be passed on to customers. ‘In case they are not passing it on, their EBITDA is likely to get affected and under the current scenario, no company will wish for it,’ an analyst with stockbroking firm Motilal Oswal Financial Services told. While the price of pet coke is currently 10-12 per cent higher than that of imported coal, its lower volume requirement means it is more cost-effective for cement producers to use.
Dalmia Bharat to acquire Murli Industries
Cement manufacturer Dalmia Bharat said its Rs 402 crore bid to acquire Murli Industries Ltd (MIL) has been approved by the Committee of Creditors (CoC) of the Nagpur-based company. The resolution plan submitted by Dalmia Cement (Bharat) Ltd, a subsidiary of Dalmia Bharat, to CoC of MMIL under the Insolvency and Bankruptcy Code, 2016 was approved recently.
‘Committee of creditors of MIL on December 20, 2017 approved the proposed resolution plan submitted by our subsidiary, DCBL for recommendation to NCLT Mumbai for its approval in relation to revival of MIL,’the company said.
It further added:
‘Following receipt of requisite approvals, the resolution plan provides for a payment of Rs 402 crore which is 1.7 times higher than the determined liquidation value.’
MIL has an integrated cement manufacturing plant with installed capacity of 3 MTPA in Chandrapur district of Maharashtra along with a captive thermal power plant of 50 MW. In addition, MIL also has paper and solvent extraction units in Maharashtra. MIL was referred to the corporate insolvency process by its lenders in April 2017. It had interests in cement, paper, solvent, power and pulp.
Coal shortage hits thermal power plants
Thermal power plants across India are facing a shortage of coal. If this situation does not improve over the next the few days, there is a real threat that power generated may stop. About 600 MW of coal-based power generation is already affected due to the coal shortage. The Western and Northern regions are the most affected, and in States such as Maharashtra and Rajasthan, about 40 per cent of power generated from coal is affected.
According to data of the Central Electricity Authority (CEA), most thermal power plants have just one to three days of reserve coal stock. Sources in Singareni Collieries say thermal plants to which it supplies coal are not facing any shortage of coal. These include plants in Telangana and Andhra Pradesh. According to CEA data, the number of thermal power plants in the country with critical stock (for only seven days) is four. The number of thermal power plants with super critical stock (for only four days) is 23.
CEA said that plants having low stocks due to outstanding dues, supply being more than committed quantity, and not lifting offered coal, are not listed in the critical and super critical data. In Andhra Pradesh, the Rayalaseema Thermal Power Station (RTPS) has coal stock for only four days, the Simhadri thermal power station has coal stock for two more days and Vizag thermal power plant has coal stock for three days. In Telangana, Ramagundam thermal power plant has coal stock for three days and Kakatiya and Kothagudem thermal power plants have coal stock for 10-21 days. There are nine plants in the northern region and 12 plants in the western region that are in critical and super critical stages.
The Union power ministry says that the issue of coal supply to power plants is being addressed in a coordinated manner by the three concerned ministries – power, coal and Railways. The Power Ministry said that this is being monitored at the highest level and that in spite of the the unprecedented rise in the demand for coal based power, due to better coordinated planning the demand of electricity in the grid is being met. More than 65 per cent of India’s electricity generation capacity comes from thermal power plants, with about 85 per cent of the country’s thermal power generation being coal-based.
The 10 biggest thermal power stations operating in India are all coal-fired.
SC allows use of pet coke in cement
The Supreme Court allowed the cement industry to use petroleum coke, a dirtier alternative to coal which had temporarily been banned as pollution levels shot up in Delhi last month. India is the world’s biggest consumer of petroleum coke, better known as pet coke, a dark solid carbon material that emits 11 per cent more greenhouse gas than coal, according to studies.
The Supreme Court in October banned the use of pet coke in and around New Delhi in a bid to clean the air in one of the world’s most polluted cities. But a blanket ban on the sale and use of petcoke could hit the country’s small and medium scale industries, which employ millions of workers and operate on thin margins, businesses say.
Supreme Court Judge Madan Bhimrao Lokur, in issuing the exemption order for cement and limestone industries, asked the government to frame guidelines for the use of pet coke. Shares of Indian cement companies, which use pet coke as feedstock, surged as much as 5 per cent on news of the court decision. Local producers of pet coke include Indian Oil Corp, Reliance Industries and Bharat Petroleum Corp.
Cement prices firm up in South
Prices of cement have jumped by an average Rs 25-30 per bag in the Southern States. The price is now hovering around Rs 310-320 per bag in Andhra Pradesh and Telangana. In Karnataka, its around Rs 340, while in Tamil Nadu and Kerala, it is being sold at over Rs 360. The prices were in the range of Rs 280 in Andhra Pradesh and Telangana. The present increase has not been normal, says M Prasad, a wholesale dealer of leading cement brands here. ‘Normally prices go up as the construction activity picks up during February to July for the year, which is seen as the best season for price realisation,’ he added.
Interestingly, the summer of 2017 proved different to the earlier three-four summers as prices unusually fell to around Rs 270 in Andhra Pradesh and Telangana. Typically, the prices are at peak with demand picking up and construction activity in full swing.
There has been no change in other factors such as production capacity and demand. Still the capacity utilisation and demand are under 40 per cent. The second quarter had seen a price erosion.
As per industry data, prices from August, September to October show that price erosion was in the range of Rs 5 in Andhra Pradesh and Telangana markets.
In Bengaluru, the prices remained more or less stable. Chennai also saw a drop of another Rs 5-10. In the days to come, the expected volume growth in the industry could be varied.
In Andhra Pradesh, the non-grounding of works related to the new capital Amaravati did not give the anticipated boost to the industry. The industry is hoping to gain from new capital probably a year and year-and-a-half from now in a slow fashion to be ramped up later. Even in Telangana, the real estate sector in the capital Hyderabad, is seeing ups and downs as far as new projects are concerned.
Cement, steel at the core of strongest infra show in a year
India’s infrastructure sector logged the highest growth in more than a year in November, while the country’s biggest carmakers reported double-digit sales growth in December, kicking off the new year on a positive note for the economy and pointing to a persistent revival trend. The index of eight core industries rose 6.8 per cent in November, the Government data showed, riding high on growth in cement and steel sectors. These have a weight of more than 40 per cent in the Index of Industrial Production (IIP), suggesting strong industrial growth in November after a dismal October.
‘Steel and cement growth at very high growth rates of 16.6 per cent and 17.3 per cent indicates restoration of the production in these sectors over pre-demonetisation levels which augurs well for real sector investment,’ said Economic Affairs Secretary, Subhash Chandra Garg.
Part of the rise is due to the favourable base effect stemming from the disruption in the wake of demonetisation in November 2016 that will prevail over the next few months.
The core sector grew 3.6 per cent in November 2016. The core sector growth in November 2017 was the best since 7.1 per cent in October 2016.
‘The early indicators for industrial production in the organised sectors in November 2017 provide favourable signals, such as the uptick in growth of the core sector and sharp improvement in the expansion of automobile production and non-oil merchandise exports,’ said Aditi Nayar, Principal Economist, ICRA.
India’s GDP growth recovered to 6.3 per cent in the July-September period from a three-year low of 5.7 per cent in the preceding quarter. Most experts had expected a stronger rebound as the impact of demonetisation and rollout of GST in July had faded.
CIL assures captive power producers of coal supply
State-owned miner Coal India (CIL) has assured coal availability to power industry body ICPPA, whose members include firms from steel and aluminium segment, as they are heavily dependent on the dry fuel. CIL Chairman and MD Gopal Singh along with other senior officials held a meeting with members of Indian Captive Power Producers Association (ICPPA). In India, captive power producers’ capacity stands at 40,000 Mega Watts (MW) and about 30,000 MW is produced by using coal, which is about 75 per cent. The rest is produced through alternate materials like gas-based and others, ICPPA General Secretary Rajiv Agarwal told.
‘The industry is highly dependent on coal and the government must understand this. There are many plants who are on the verge of shut down. Many may become a non-performing asset (NPA),’ he said. CIL, in the meeting, said about 71 per cent materialisation of coal was done during April-December 2017 for both IPPs (integrated power producers) and CPPs and assured there is no shortage of coal.
ICPPA said it is not satisfied by the words of the PSU, who it said is supposed to supply the dry fuel to industry. Agarwal said, ‘The given figure included dispatches by both rail and road. The share of CPPs rail dispatches is in the range of only 30 to 50 per cent and out of this 30 per cent major supply was given to those plants who were near the pits.’
Even if coal linkage auction is concerned, 41.5 MT was offered to the CPPs, he said and added, that out this the industry could not bid for 8.5 MT offered at ‘Magad-Amrapali of CCL (Central Coalfields Ltd)’ a place with evacuation constraint.

Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, delves into how digital intelligence is transforming cement grinding into a predictive, stable, and energy-efficient operation.
Grinding sits at the heart of cement manufacturing, accounting for the largest share of electrical energy consumption. In this interview, Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, explains how advanced grinding technologies, data-driven optimisation and process intelligence are transforming mill performance, reducing power consumption and supporting the industry’s decarbonisation goals.
How has the grinding process evolved in Indian cement plants to meet rising efficiency and sustainability expectations?
Over the past decade, Indian cement plants have seen a clear evolution in grinding technology, moving from conventional open-circuit ball mills to high-efficiency closed-circuit systems, Roller Press–Ball Mill combinations and Vertical Roller Mills (VRMs). This shift has been supported by advances in separator design, improved wear-resistant materials, and the growing use of digital process automation. As a result, grinding units today operate as highly controlled manufacturing systems where real-time data, process intelligence and efficient separation work together to deliver stable and predictable performance.
From a sustainability perspective, these developments directly reduce specific power consumption, improve equipment reliability and lower the carbon footprint per tonne of cement produced.
How critical is grinding optimisation in reducing specific power consumption across ball mills and VRMs?
Grinding is the largest consumer of electrical energy in a cement plant, which makes optimisation one of the most effective levers for improving energy efficiency. In ball mill systems, optimisation through correct media selection, charge design, diaphragm configuration, ventilation management and separator tuning can typically deliver power savings of 5 per cent to 8 per cent. In VRMs, fine-tuning airflow balance, grinding pressure, nozzle ring settings, and circulating load can unlock energy reductions in the range of 8 per cent to 12 per cent. Across both systems, sustained operation under stable conditions is critical. Consistency in mill loading and operating parameters improves quality control, reduces wear, and enables long-term energy efficiency, making stability a key operational KPI.
What challenges arise in maintaining consistent cement quality when using alternative raw materials and blended compositions?
The increased use of alternative raw materials and supplementary cementitious materials (SCM) introduces variability in chemistry, moisture, hardness, and loss on ignition. This variability makes it more challenging to maintain consistent fineness, particle size distribution, throughput and downstream performance parameters such as setting time, strength development and workability.
As clinker substitution levels rise, grinding precision becomes increasingly important. Even small improvements in consistency enable higher SCM utilisation without compromising cement performance.
Addressing these challenges requires stronger feed homogenisation, real-time quality monitoring and dynamic adjustment of grinding parameters so that output quality remains stable despite changing input characteristics.
How is digital process control changing the way grinding performance is optimised?
Digital process control is transforming grinding from an operator-dependent activity into a predictive, model-driven operation. Technologies such as online particle size and residue analysers, AI-based optimisation platforms, digital twins for VRMs and Roller Press systems, and advanced process control solutions are redefining how performance is managed.
At the same time, workforce roles are evolving. Operators are increasingly focused on interpreting data trends through digital dashboards and responding proactively rather than relying on manual interventions. Together, these tools improve mill stability, enable faster response to disturbances, maintain consistent fineness, and reduce specific energy consumption while minimising manual effort.
How do you see grinding technologies supporting the industry’s low-clinker and decarbonisation goals?
Modern grinding technologies are central to the industry’s decarbonisation efforts. They enable higher incorporation of SCMs such as fly ash, slag, and limestone, improve particle fineness and reactivity, and reduce overall power consumption. Efficient grinding makes it possible to maintain consistent cement quality at lower clinker factors. Every improvement in energy intensity and particle engineering directly contributes to lower CO2 emissions.
As India moves toward low-carbon construction, precision grinding will remain a foundational capability for delivering sustainable, high-performance cement aligned with national and global climate objectives.
How much potential does grinding optimisation hold for immediate energy
and cost savings?
The potential for near-term savings is substantial. Without major capital investment, most plants can achieve 5 per cent to 15 per cent power reduction through measures such as improving separator efficiency, optimising ventilation, refining media grading, and fine-tuning operating parameters.
With continued capacity expansion across India, advanced optimisation tools will help ensure that productivity gains are not matched by proportional increases in energy demand. Given current power costs, this translates into direct and measurable financial benefits, making grinding optimisation one of the fastest-payback operational initiatives available to cement manufacturers today.

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.
