Detlef Blümke, Managing Director, Loesche India, talks about the evolution and adaptation of grinding mills with the changing face of raw mix and alternative fuels.
Let us start at the beginning, somewhere around 1906, when Loesche India initiated coal fired power plants and mills. Since then, they have been developing new things and have been frontrunners in the vertical mills’ domain. They are inventors of raw mills for raw material grinding, vertical roller mills for raw material grinding and have been ahead of times with other manufacturers following their lead. Energy and carbon dioxide are the major concerns in the current times. Loesche India is developing and trying to improve its product to accommodate the rising concerns of the environment. Europe, too, is very strict with its regulations as carbon reduction is a huge necessity there as well. This will ultimately imply the reduction of work. The resource is also critical as Loesche India is shutting down its coal fired power plants and looking forward to using nuclear powered or solar powered plants etc., which safeguard and protect the resources of nature. They are the inventors of hundreds of machines, which makes them responsible for cleaning up the world that we live in. The company has partnered with multiple companies and have been working on processes like pyroprocessing, focussing on aspects like power reduction, process optimisation and carbon reduction. While it is not trying to compete with full line suppliers, it is looking for niche markets and focusing on each product.
Finetuning the Operations One of Loesche India’s subsidiaries in India is into transportation and has special transportation machinery that is not available anywhere. This ensures a smooth process because if that is interrupted, then it needs to be restarted and stopped, which leads to waste of energy. The company is working on a wide field of products and is moving ahead with new developments to increase capacities of its mills and to reduce the footprints of the plants. It has acquired small portions of land in some areas, because it is not just about the investment, it is also about the protection of land. It is also working on replacing limestone in the clinker, which is clinker reduction, which leads to reduction in the consumption of power and carbon. This is the main focus. Dr Loesche is 67 years old and his sons will be stepping in to take over the business. They are deeply inclined towards environment protection and building sustainability. The organisation has also started publishing its sustainability reports and are looking into it minutely to understand better paths to include sustainability into their machines and everyone’s lives as well. Speaking of alternative fuels, at the celebration of 111 years of Loesche, it was announced that the company is using 100 per cent alternative fuels without any coal. At this stage, the machines have been optimised for the use of 60 to 70 per cent alternative fuels to 100 per cent alternative fuels. They have optimised the plant process for the same. Newer cements will keep getting developed by the producers, which will be further approved by the concerned authorities. Clay and slag are substitutes, which are alternative or supplementary materials. Loesche India’s raw mills are equipped to adapt to the changing raw materials for cement and will give optimised results for the same.
Role of Automation They have onboarded subsidiaries and companies that conduct fluid simulations for their processes to understand if the results can be optimised and identify bottlenecks for a seamless flow. This way resistance can be eliminated, thus reducing the usage of power. They also provide their customers with gear boxes for our machines, so that preventive maintenance can be done for any damage that may be waiting to happen. They give a full package with machines, spare parts, documentation and software packages for self-learning for optimised results. They are far away from advanced artificial intelligence. The acceptance of full automation in India is still not 100 per cent, but they are moving there. As the players are increasing their capacities and competition is rising, the industry will be inclined to automate their processes. Loesche India has introduced an ambient system, especially for raw material grinding, which can reduce the footprint of grinding, can reduce CAPEX and operational cost as well. This system will be able to reduce at least 2kWH per tonne for the grinding. If the capacity is 600 or 900 tonnes, the savings are enormous. This is the company’s main focus to reduce energy and save the environment. It is no longer looking at capacities anymore, attractive plants are green now. Loesche India has been in the Indian market for almost 40 years and is well reputed in India. It is constantly working towards keeping up with its innovations and inventions. Of course, the competition is strong, but that is a challenge that the company has happily accepted and is pushing the boundaries to become better, with machines that are more reliable and energy efficient as it continues to be a part of the cement industry in India.

Crisil said operating margins of Indian cement manufacturers are expected to decline by Rs 50-75 per tonne (t) this fiscal to Rs 925-950 per t due to higher input costs triggered by the West Asia conflict. The analysis covered 18 cement companies accounting for nearly 90 per cent of India’s domestic cement capacity and noted margins had improved sharply to around Rs 1,000 per t in fiscal 2026.
Crisil noted that the reduction would be driven mainly by higher power and fuel costs, which account for about 30 per cent of total costs, as petcoke and imported coal prices have surged amid geopolitical uncertainties. Freight costs, which account for about a quarter of total costs, are also expected to remain elevated because of higher diesel prices. The impact on profitability is likely to be more pronounced in the first half of the fiscal year before easing commodity prices moderate cost pressures later.
The rating agency said steady domestic demand and strong balance sheets should keep credit profiles stable despite the moderation in margins. Green energy currently accounts for 35-40 per cent of the sector’s total electricity consumption and is expected to partly cushion higher energy costs. Operating cash flows are likely to remain resilient, supported by projected 6-7 per cent growth in cement demand this fiscal.
Crisil highlighted that demand growth will be driven primarily by infrastructure spending, which meets about one-third of sector consumption, and by a nearly 18 per cent higher budgetary allocation for core ministries that should support project execution. Weaker rural housing demand amid pressure on agricultural incomes from a possible below-average monsoon may be offset by improved urban housing demand supported by favourable home-loan rates and a strong pipeline of Pradhan Mantri Awas Yojana-Urban projects. Ongoing capacity additions will keep capital expenditure elevated and may lift net debt to EBITDA to between 1.2 and 1.4 times from around 1.0 time last fiscal, though ratios are expected to remain healthy.
UltraTech Cement’s board of directors has approved raising Rs 5,000 crore (Rs 50 bn) through non?convertible debentures issued in rupees.
The finance committee cleared a proposal to issue up to 500,000 fully paid, unsecured, listed, rated, redeemable, rupee?denominated, non?convertible, non?cumulative debentures of Rs 1 lakh each (Rs 0.1 mn each), aggregating to the Rs 5,000 crore programme.
As of June 2026 the firm reported net debt of Rs 15,875 crore (Rs 158.75 bn) and said its capacity expansion projects under execution are backed by capital expenditure of about Rs 17,000 crore (Rs 170 bn) over the next two to two?and?a?half years.
UltraTech spent Rs 9,500 crore (Rs 95 bn) on capital expenditure in financial year 2026 and in April the group crossed 200.1 mn tonnes per annum of domestic grey cement capacity and 205.5 mn tonnes per annum of global capacity.
The chief financial officer indicated the company would take consolidated capacity beyond 242 mn tonnes per annum, with grey cement capacity reaching 212.7 mn tonnes per annum by the end of financial year 2027. He noted the net debt?to?earnings before interest, taxes, depreciation and amortisation ratio stood at 0.87 times as of June 2026 and the company was confident of ending financial year 2027 with the ratio below one time.
In the first quarter of financial year 2026?27 UltraTech’s net profit attributable to owners rose 16.8 per cent year?on?year to Rs 2,599.3 crore (Rs 25.993 bn) and revenue from operations increased 15.9 per cent to Rs 24,648.20 crore (Rs 246.482 bn). The board approval is expected to complement internal cash flows as the company advances its expansion programme.
Andhra Pradesh Education and IT Minister Nara Lokesh on Wednesday laid the foundation stone for the Line-2 expansion of Dalmia Bharat Cement at Chinnakomerla village in Mylavaram Mandal in Kadapa district. The project carries an investment of Rs 31 billion (bn) and is slated for completion by the third quarter of the financial year 2028. The expansion is intended to boost industrial growth and employment generation across the Rayalaseema region.
Once commissioned, the Kadapa facility will become Dalmia Bharat’s largest integrated cement manufacturing ecosystem in southern India, creating over 1,000 direct and indirect jobs and opening new business avenues for regional micro, small and medium enterprises and transport operators. Lokesh said the expansion signalled growing corporate confidence in the state and reflected the practical ease of doing business that secured repeat investment.
He placed the project within the government’s wider economic targets and recalled the Yuvagalam padayatra commitment to generate two million (mn) jobs within five years, noting that the state would cultivate talent while industry created opportunities. Lokesh highlighted Andhra Pradesh’s competitive pursuit of major manufacturing accounts, mentioning past successes and a personal initiative to engage global investors when persuading them to anchor expansion in the state.
The plant will leverage Kadapa’s abundant limestone reserves to scale production and sustainability. Clinker capacity is planned to rise from two point five million tonnes per annum (mn tpa) to six point one mn tpa, while overall cement output will increase from three point six mn tpa to nine point six mn tpa. The unit is designed to operate on over eighty per cent renewable energy and deploy waste heat recovery, zero liquid discharge, water recycling and advanced AI systems to optimise efficiency. Industries Minister TG Bharat, BC Welfare Minister S. Savitha and Jammalamadugu MLA C. Adinarayana Reddy attended the ceremony.
