Dyanesh Wanjale, Managing Director, Gebr. Pfeiffer discusses the need to innovate grinding technologies to make the manufacturing process more efficient and less fuel consuming.

Gebr. Pfeiffer stands at the forefront of grinding technology, delivering energy-efficient and customised solutions for cement manufacturers worldwide. From pioneering vertical roller mills to integrating AI-driven optimisation, the company is committed to enhancing efficiency and sustainability. In this interview, we explore how their cutting-edge technology is shaping the future of cement production.

Can you tell us about the grinding technology your company offers and its role in the cement industry?
We are pioneers in grinding technology, with our company being based in Germany and having a rich history of over 160 years, a milestone we will celebrate in 2024. We are widely recognised as one of the most efficient grinding technology suppliers globally. Our MBR mills are designed with energy efficiency at their core, and for the past five years, we have been focused on continuous improvements in power consumption and reducing the CO2 footprint. Innovation is an ongoing process for us, as we strive to enhance efficiency while supporting the cement industry’s sustainability goals. Our technology plays a critical role in helping manufacturers reduce their environmental impact while improving productivity.

The use of alternative fuels and raw materials (AFR) is an ever-evolving area in cement production. How does your technology adapt to these changes?
Our vertical roller mills are specifically designed to adapt to the use of alternative fuels and raw materials. These mills are energy-efficient, which is a key advantage when working with AFR since alternative fuels often generate less energy. By consuming less power, our technology helps bridge this gap effectively. Our solutions ensure that the use of AFR does not compromise the operational efficiency or productivity of cement plants. This adaptability positions our technology as a vital asset in the industry’s journey toward sustainability.

What are some of the challenges your company faces, both in the Indian and global cement industries?
One of the major challenges we face is the demand for expedited deliveries. While customers often take time to decide on placing orders, once the decision is made, they expect quick deliveries. However, our industry deals with heavy and highly customised machinery that cannot be produced off the shelf. Each piece of equipment is made-to-order based on the client’s unique requirements, which inherently requires time for manufacturing.
Another significant challenge comes from competition with Chinese suppliers. While the Indian cement industry traditionally favoured our technology over Chinese alternatives, a few customers have started exploring Chinese vertical roller mills. This is concerning because our German technology offers unmatched quality and longevity. For example, our mills are designed to last over 30 years, providing a long-term solution for customers. In contrast, Chinese equipment often does not offer the same durability or reliability. Despite the cost pressures, we firmly believe that our technology provides superior value in the long run.

You mentioned that your machinery is made-to-order. Can you elaborate on how you customise equipment to meet the specific requirements of different cement plants?
Absolutely. Every piece of machinery we produce is tailored to the specific needs of the customer. While we have standard mill sizes to cater to different capacity requirements, the components and configurations are customised based on the client’s operational parameters and budget. This process ensures that our solutions deliver optimal performance and cost efficiency. Since these are heavy and expensive items, maintaining an inventory of pre-made equipment is neither practical nor economical. By adopting a made-to-order approach, we ensure that our customers receive machinery that precisely meets their needs.

The cement industry is focusing not only on increasing production but also on decarbonising operations. How does your company contribute to this dual objective, and how do you see this evolving in the future?
Decarbonisation is a key focus for our research and development efforts. We are continuously working on innovative solutions to reduce CO2 emissions and improve overall sustainability. For example, we have significantly reduced water consumption in our processes, which was previously used extensively for stabilisation. Additionally, we are leveraging artificial intelligence to optimise mill operations. AI enables us to monitor the process in real-time, analyse feedback, and make adjustments to achieve optimal results within the given parameters.
Our commitment to innovation ensures that we are not only helping the industry decarbonise but also making operations more efficient. As the cement industry moves toward stricter sustainability goals, we are confident that our technology will play a pivotal role in achieving them.

Can you provide more details about the use of digitalisation and artificial intelligence in your processes? How does this improve your operations and benefit your customers?
Digitalisation and AI are integral to our operations, enabling us to offer advanced monitoring and optimisation solutions. We have developed three distinct models that allow customers to monitor mill performance through their computer systems. Additionally, our technology enables real-time feedback from our German headquarters to the customer. This feedback highlights any inefficiencies, such as when a parameter is outside the optimal range,
and provides actionable recommendations to address them.
By continuously monitoring every parameter in real time, our AI-driven systems ensure that mills operate at peak efficiency. This not only enhances production but also minimises downtime. I am proud to say that our mills have the lowest shutdown rates compared to other manufacturers. This reliability, combined with the insights provided by our digital solutions, ensures that customers achieve consistent and efficient operations. It’s a game-changer for reducing costs and enhancing overall productivity.

The Department of Science and Technology (DST) recently unveiled a pioneering national initiative: five Carbon Capture and Utilisation (CCU) testbeds in the cement sector, forming a first-of-its-kind research and innovation cluster to combat industrial carbon emissions.
This is a significant step towards India’s Climate Action for fostering National Determined Contributions (NDCs) targets and to achieve net zero decarbonisation pathways for Industry Transition., towards the Government’s goal to achieve a carbon-neutral economy by 2070.
Carbon Capture Utilisation (CCU) holds significant importance in hard-to-abate sectors like Cement, Steel, Power, Oil &Natural Gas, Chemicals & Fertilizers in reducing emissions by capturing carbon dioxide from industrial processes and converting it to value add products such as synthetic fuels, Urea, Soda, Ash, chemicals, food grade CO2 or concrete aggregates. CCU provides a feasible pathway for these tough to decarbonise industries to lower their carbon footprint and move towards achieving Net Zero Goals while continuing their operations efficiently. DST has taken major strides in fostering R&D in the CCUS domain.
Concrete is vital for India’s economy and the Cement industry being one of the main hard-to-abate sectors, is committed to align with the national decarbonisation commitments. New technologies to decarbonise emission intensity of the cement sector would play a key role in achieving of national net zero targets.
Recognizing the critical need for decarbonising the Cement sector, the Energy and Sustainable Technology (CEST) Division of Department launched a unique call for mobilising Academia-Industry Consortia proposals for deployment of Carbon Capture Utilisation (CCU) in Cement Sector. This Special call envisaged to develop and deploy innovative CCU Test bed in Cement Sector with thrust on Developing CO2 capture + CO2 Utilisation integrated unit in an Industrial set up through an innovative Public Private Partnership (PPP) funding model.
