Mineral Sizers: MMD sizer technology

Published

Shares

MMD (Mining Machinery Developments), the inventor and patent holder of the twin shaft mineral sizer, is playing an ever-increasing role in the world’s cement industry.

The MMD mineral sizer was originally designed in 1978 to meet the requirements of the British underground coal mining industry. Having successfully achieved this in the demanding underground coal mining environment, it became evident that the unique attributes and advantages of the MMD twin shaft mineral sizer could be applied to other underground and surface applications and industries. Today, MMD can process over 65 different minerals worldwide, in many varied process industries.

The first unit in to the cement industry was delivered to Cauldon cement works in the UK, (then part of Blue Circle Cement, now Lafarge), in the early 1980s. In contrast to the smaller 500mm centres machines supplied to the underground coal mines, this was a larger unit with 1000mm shaft centres, designed to handle large pieces of shale. This 1000 Series sizer rapidly proved its capabilities as a primary crusher and after providing years of valuable service at the cement plant has been sold to an opencast mine in the Philippines, where it is still working today. This machine was soon followed by another, this time to size sticky clay containing hard material within it. Despite there being specialist clay machines on the market, the issue of sizing this mix of materials was a universal problem, and again the MMD machine proved to be an instant success, and very quickly the industry came to appreciate the unique capabilities of the MMD twin shaft mineral sizer. The MMD 750 Series twin shaft sizer has also been successfully employed in a secondary role at the Cauldon Cement Works for many years and has recently undergone an upgrade to bring its capacity to 1200tph.

Although the major portion of MMD’s interface with the cement industry is still in hard rock quarries and clay, it is by no means confined to these areas, MMD having gone on to increase their product range to include equipment such as their heavy- duty plate feeder, and adapt existing products to meet the requirements of the cement industry.

Against many odds

In the current economic climate of rapidly rising fuel costs and with environmental pressures being felt across all industries around the world, the importance of the cement industry taking a new look at the significant progress being made regarding these issues in the allied mining industry, cannot be underrated.

Although the volume of the raw materials required by the cement industry is low compared with mining, it is a highly visible and therefore potentially contentious element in the production chain, as cement plants tend to be developed close to the markets, and hence in more sensitive areas. A situation which makes the growing use of In-Pit Crushing and Conveying (IPCC) rather than truck haulage, an area of particular significance. Not only does IPCC allow for a reduction in the dependence on expensive oil based fuel, it is seen as being eco-friendly due to the potential reduction (or elimination) of green-house gasses in exhaust fumes as well as the noise and dust generated by trucks.

Mobile crushers and IPCC are not new concepts and their benefits are well established within quarrying. However, the vast majority of these quarries produce at a lower rate than is generally required by cement plants. But this scenario is changing, due to both the unprecedented boom in the commodities market and rapid urbanisation. New IPCC installations in mining and articles and conferences dedicated to this technology, have resulted in a proliferation of the number of companies which are developing or attempting to develop high capacity equipment for the burgeoning IPCC market. This is a field where MMD, who have championed the use of mobile sizing equipment in both the mining and cement industries, can justifiably lay claim to being world leaders, having consistently been involved in this market for over 25 years. During this time, they have installed a host of semi-mobile units, as well as a significant number of low (under 1000tph), medium (2-3000tph), and high capacity (over 5000tph) fully mobile sizers around the world. The unique know-how and experience gained has allowed them to be able to offer the best possible unit, with all the inherent benefits of mobility to the cement industry. However, for the cement industry especially, it is not enough for a potential supplier to be capable of providing high capacity units. The demands for flexibility, consistency in product size and chemistry are onerous. The real need being for equipment which is capable of handling a range of material having very different physical characteristics, as the requirement for a chemically consistent product usually involves blending the core limestone with different often sticky materials.

Breaking and mixing

A prime example of this is the use of the sizer to not only break, but mix the material too; the MMD twin shaft sizer’s contra-rotating shafts and scroll action are ideal for blending the different materials, even those with very different constituencies and moisture content. An increasing number of cement plants are using the MMD sizer in this breaking-cum-blending role. A cross- belt analyser is linked to the variable speed drive of the apron plate feeders, feeding limestone, clay and additives into the sizer, thus ensuring a consistent mix of material to the stockpile and eliminating the need for separate stockpiles and the problems associated with the stockpiling of sticky clay material.

MMD’s existing record within the cement industry and the established features and benefits of the mineral sizer, will hopefully lead to an increased use of this now well established technology. The MMD twin shaft mineral sizer is not limited to a high capacity primary sizing role, there have been numerous examples of cases where the installation of an MMD sizer has either replaced or supplemented the existing equipment when problems have been encountered. For example, in Belgium an MMD sizer was installed in a plant that had been running for many years, where the ever- increasing stickiness was causing problems for the existing roll crusher. The compact size and low profile allowed MMD to install the sizer over an existing conveyor line, involving minimal expense and complication.

Similarly, this new cement plant designed and installed by one the world`s leading cement manufacturers suffered severe production hold-ups due to the amount of clay in the system. The problem was put to MMD, who quickly resolved the situation with a simple installation of a 500 Series sizer within the existing plan, successfully allowing the plant to run at full production.

Some of the most recent orders won by MMD to supply equipment to the cement industry include: A 500 Series twin shaft sizer to process 200tph of clay, from an in-feed size of 350mm to a product size of 80mm, for an Ital Cement plant in Italy. For Volsk Cement in Russia, an apron plate feeder and two 500 Series Twin shaft sizers to reduce gypsum slag (additives) from 350mm in-feed down to 75mm at a rate of 150tph. Plus, for the same plant; a 350 Series machine to reduce gypsum from a feed size of 75mm to a 25mm product at 22tph.

Having supplied their technology worldwide to a variety of cement producers such as Holcim, Cemex, Lafarge, Heidelberg, Italcementi, CRH, Buzzi and Titan Cement as well as to leading cement plant designers such as FLS and Polysius, MMD can justifiably lay claim to a position amongst the leading suppliers to the cement industry.

Arasu Shanmugam, Director and CEO-India, IFGL, discusses the diversification of the refractory sector into the cement industry with sustainable and innovative solutions, including green refractories and advanced technologies like shotcrete.

Tell us about your company, it being India’s first refractory all Indian MNC.
IFGL Refractories has traditionally focused on the steel industry. However, as part of our diversification strategy, we decided to expand into the cement sector a year ago, offering a comprehensive range of solutions. These solutions cover the entire process, from the preheater stage to the cooler. On the product side, we provide a full range, including alumina bricks, monolithics, castables, and basic refractories.
In a remarkably short span of time, we have built the capability to offer complete solutions to the cement industry using our own products. Although the cement segment is new for IFGL, the team handling this business vertical has 30 years of experience in the cement industry. This expertise has been instrumental in establishing a brand-new greenfield project for alumina bricks, which is now operational. Since production began in May, we are fully booked for the next six months, with orders extending until May 2025. This demonstrates the credibility we have quickly established, driven by our team’s experience and the company’s agility, which has been a core strength for us in the steel industry and will now benefit our cement initiatives.
As a 100 per cent Indian-owned multinational company, IFGL stands out in the refractory sector, where most leading players providing cement solutions are foreign-owned. We are listed on the stock exchange and have a global footprint, including plants in the United Kingdom, where we are the largest refractory producer, thanks to our operations with Sheffield Refractories and Monocon. Additionally, we have a plant in the United States that produces state-of-the-art black refractories for critical steel applications, a plant in Germany providing filtering solutions for the foundry sector, and a base in China, ensuring secure access to high-quality raw materials.
China, as a major source of pure raw materials for refractories, is critical to the global supply chain. We have strategically developed our own base there, ensuring both raw material security and technological advancements. For instance, Sheffield Refractories is a leader in cutting-edge shotcreting technology, which is particularly relevant to the cement industry. Since downtime in cement plants incurs costs far greater than refractory expenses, this technology, which enables rapid repairs and quicker return to production, is a game-changer. Leading cement manufacturers in the country have already expressed significant interest in this service, which we plan to launch in March 2025.
With this strong foundation, we are entering the cement industry with confidence and a commitment to delivering innovative and efficient solutions.
Could you share any differences you’ve observed in business operations between regions like Europe, India, and China? How do their functionalities and approaches vary?
When it comes to business functionality, Europe is unfortunately a shrinking market. There is a noticeable lack of enthusiasm, and companies there often face challenges in forming partnerships with vendors. In contrast, India presents an evolving scenario where close partnerships with vendors have become a key trend. About 15 years ago, refractory suppliers were viewed merely as vendors supplying commodities. Today, however, they are integral to the customer’s value creation chain.
We now have a deep understanding of our customers’ process variations and advancements. This integration allows us to align our refractory solutions with their evolving processes, strengthening our role as a value chain partner. This collaborative approach is a major differentiator, and I don’t see it happening anywhere else on the same scale. Additionally, India is the only region globally experiencing significant growth. As a result, international players are increasingly looking at India as a potential market for expansion. Given this, we take pride in being an Indian company for over four decades and aim to contribute to making Aatma Nirbhar Bharat (self-reliant India) a reality.
Moving on to the net-zero mission, it’s crucial to discuss our contributions to sustainability in the cement industry. Traditionally, we focused on providing burnt bricks, which require significant fuel consumption during firing and result in higher greenhouse gas emissions, particularly CO2. With the introduction of Sheffield Refractories’ green technology, we are now promoting the use of green refractories in cement production. Increasing the share of green refractories naturally reduces CO2 emissions per ton of clinker produced.
Our honourable Prime Minister has set the goal of achieving net-zero emissions by 2070. We are committed to being key enablers of this vision by expanding the use of green refractories and providing sustainable solutions to the cement industry, reducing reliance on burnt refractories.

Technology is advancing rapidly. What role does it play in helping you achieve your targets and support the cement industry?
Technology plays a critical role in achieving our goals and supporting the cement industry. As I mentioned earlier, the reduction in specific refractory consumption is driven by two key factors: refining customer processes and enhancing refractory quality. By working closely as partners with our customers, we gain a deeper understanding of their evolving needs, enabling us to continuously innovate. For example, in November 2022, we established a state-of-the-art research centre in India for IFGL, something we didn’t have before.
The primary objective of this centre is to leverage in-house technology to enhance the utilisation of recycled materials in manufacturing our products. By increasing the proportion of recycled materials, we reduce the depletion of natural resources and greenhouse gas emissions. In essence, our focus is on developing sustainable, green refractories while promoting circularity in our business processes. This multi-faceted approach ensures we contribute to environmental sustainability while meeting the industry’s demands.

Of course, this all sounds promising, but there must be challenges you’re facing along the way. Could you elaborate on those?
One challenge we face is related to India’s mineral resources. For instance, there are oxide deposits in the Saurashtra region of Gujarat, but unfortunately, they contain a higher percentage of impurities. On the magnesite side, India has deposits in three regions: Salem in Tamil Nadu, Almora in Uttarakhand, and Jammu. However, these magnesite deposits also have impurities. We believe the government should take up research and development initiatives to beneficiate these minerals, which are abundantly available in India, and make them suitable for producing high-end refractories. This task is beyond the capacity of an individual refractories company and requires focused policy intervention. While the government is undertaking several initiatives, beneficiation of minerals like Indian magnesite and Indian oxide needs to become a key area of focus.
Another crucial policy support we require is recognising the importance of refractories in industrial production. The reality is that without refractories, not even a single kilogram of steel or cement can be produced. Despite this, refractories are not included in the list of core industries. We urge the government to designate refractories as a core industry, which would ensure dedicated focus, including R&D allocations for initiatives like raw material beneficiation. At IFGL, we are taking proactive steps to address some of these challenges. For instance, we own Sheffield Refractories, a global leader in shotcrete technology. We are bringing this technology to India, with implementation planned from March onwards. Additionally, our partnership with Marvel Refractories in China enables us to leverage their expertise in providing high-quality refractories for steel and cement industries worldwide.
While we are making significant efforts at our level, policy support from the government—such as recognising refractories as a core industry and fostering research for local raw material beneficiation—would accelerate progress. This combined effort would greatly enhance India’s capability to produce high-end refractories and meet the growing demands of critical industries.

Could you share your opinion on the journey toward achieving net-zero emissions? How do you envision this journey unfolding?
The journey toward net zero is progressing steadily. For instance, even at this conference, we can observe the commitment as a country toward this goal. Achieving net zero involves having a clear starting point, a defined objective, and a pace to progress. I believe we are already moving at an impressive speed toward realising this goal. One example is the significant reduction in energy consumption per ton of clinker, which has halved over the past 7–8 years—a remarkable achievement.
Another critical aspect is the emphasis on circularity in the cement industry. The use of gypsum, which is a byproduct of the fertiliser and chemical industries, as well as fly ash generated by the power industry, has been effectively incorporated into cement production. Additionally, a recent advancement involves the use of calcined clay as an active component in cement. I am particularly encouraged by discussions around incorporating 12 per cent to 15 per cent limestone into the mix without the need for burning, which does not compromise the quality of the final product. These strategies demonstrate the cement industry’s constructive and innovative approach toward achieving net-zero emissions. The pace at which these advancements are being adopted is highly encouraging, and I believe we are on a fast track to reaching this critical milestone.
