Jens Mose and John Terembula, Product Line Management, FLSmidth A/S, explore how cement manufacturers can utilise VRMs to reduce the clinker factor and meet their environmental targets, in the final part of this three-part series. You can find parts one and two in the August and September issues of Indian Cement Review.
OPTIMISING PARTICLE SIZE DISTRIBUTION Experience has shown that practically every type of cement around the world can be – and is already being – produced in an OK MillTM. While the particle size distribution (PSD) of the product is normally steeper in a VRM cement mill compared to a traditional ball mill, this can, to some extent, be modified by working with various parameters such as grinding pressure and dam ring height. The air flow and the separator speed are also used to customise the PSD curve to customer specific requirements. However, as interest in greater utilisation of SCMs increases, cement manufacturers are keen to grind to an even steeper PSD curve to allow for the possibility of mixing more SCMs into the finished product.
THE ADVANTAGES OF VRMS FOR SCMS When the VRM is designed specifically for grinding cement and cementitious materials, cement manufacturers experience better:
Efficiency: Lowest power consumption compared to other vertical roller mills on the market.
Reliability: The run factor is very high, > 95 per cent
Versatility: Rapid change between different feed compositions and the ability to grind a wide range of materials to very high Blaine or the lowest residues
The OK MillTM was designed with these priorities in mind, and has retained its original shape with a dual lobed roller surface and central grooved and bowl-shaped table design. As the only VRM in the market specifically designed for cement grinding, all rollers are active with each performing material bed compaction and de-aeration, and high-pressure grinding. Sustainability is also a priority, which is why the mill is designed to require minimal water injection on the mill table, using an average 50 per cent less water than competing mill designs.
Maintenance is also a sustainability issue. Better to repair a part than replace it; better to be proactive than reactive. Predictive maintenance services aim to enable a higher level of proactivity, preventing unexpected downtime and reducing the cost of maintenance. Over the last 20 years, in-situ rewelding or hard facing has become the standard maintenance practice for VRM, particularly for OK MillsTM with segmented wear liners that can tolerate repeated welding. Roller liner segments can be rewelded as many as 10 times or more and table segments 15 times or more. In order to improve its service capability for VRMs, FLSmidth works with welding services providers across the globe. We have also developed ceramic wear segments in an OK MillTM, which not only perform better but can also be recycled.
DIGITAL TOOLS FOR GREATER FLEXIBILITY Digitalisation makes it easier to use SCMs and will enable further reductions in the clinker factor. The following are just a snapshot of the tools currently available; more are in development all the time:
Process control solutions give operators greater control over their mill operating parameters to optimise performance and ensure maximum efficiency.
Sensors continually monitor mill operation, enabling you to see any drop in stability as it happens and react swiftly.
Automated laboratories enable optimum quality control throughout the process.
Condition monitoring services and remote service support give you 24/7 access to expert assistance.
CONCLUSION As the cement industry works to reduce its carbon footprint, investments have to be made in future-proof technologies capable of adapting to changing cement mixes and regulatory requirements. In the grinding process, cement manufacturers need a flexible, efficient system that is operated and maintained in an optimal manner. With the latest VRM technologies, advanced digital offerings and condition monitoring services, FLSmidth believes the industry is ready to achieve more widespread use of SCMs and achieve its carbon reduction goals.
UltraTech Cement has appointed Jayant Dua as managing director (MD) designate who will take charge in 2027, the company announced. The appointment signals a planned leadership transition at one of the country’s largest cement manufacturers. The board has set a clear timeline for the handover and has framed the move as part of a structured succession plan.

MPS said the acquisition will support its planned development pipeline and enable delivery of commercial and residential space to meet local demand.
The company expects the site to provide flexibility in product design and phased development to respond to market conditions.
The move reflects an emphasis on land ownership in key suburban markets.
The emphasis on land acquisition reflects a strategy to secure inventory ahead of demand cycles.
The purchase follows a period of sustained investor interest in Pune real estate, driven by expanding office ecosystems and residential demand from professionals.
MPS will integrate the new holding into its existing portfolio and plans to engage with local authorities and stakeholders to progress approvals and infrastructure readiness.
No financial partners were disclosed in the announcement.
The firm indicated that timelines will depend on approvals and prevailing market conditions.

Adani Cement has entered a strategic partnership with the National Real Estate Development Council (Naredco) to support India’s construction needs with a focus on sustainability, workforce capability and modern building technologies. The collaboration brings together Adani Cement’s building materials portfolio, research and development strengths and technical expertise with Naredco’s nationwide network of more than 15,000 member organisations. The agreement aims to address evolving demand across housing, commercial and infrastructure sectors.
Under the partnership, the organisations will roll out skill development and certification programmes for masons, contractors and site supervisors, with training to emphasise contemporary construction techniques, safety practices and quality standards. The programmes are intended to improve project execution and on-site efficiency and to raise labour productivity through standardised competencies. Emphasis will be placed on practical training and certification pathways that can be scaled across regions.
The alliance will function as a platform for knowledge sharing and technology exchange, facilitating access to advanced concrete solutions, innovative construction practices and modern materials. The effort is intended to enhance structural durability, execution quality and environmental responsibility across developments while promoting adoption of low-carbon technologies and green cement alternatives. Companies expect these measures to contribute to longer term resilience of built assets.
Senior executives conveyed that the partnership reflects a shared commitment to strengthening quality and sustainability in construction and that closer engagement with developers will help integrate advanced materials and technical support throughout the project lifecycle. Leadership noted the need for responsible construction practices as urbanisation accelerates and indicated that the association should encourage wider adoption of green building norms and collaboration within the real estate and construction ecosystem.
The organisations said they will also explore integrated building solutions, including ready-mix concrete offerings, while supporting initiatives aligned with affordable and inclusive housing. The partnership will progress through engagements, conferences and joint training programmes targeting rapidly urbanising cities and growth centres where demand for efficient and environmentally responsible construction grows. Naredco, established under the aegis of the Ministry of Housing and Urban Affairs, will leverage its policy and advocacy role to support implementation.
