Whether grinding raw coal, clinker, cement and/or slag, we have a VRM solution to suit your grinding needs. What’s more, our online condition monitoring services enable you to adopt a proactive maintenance strategy for your OK™ and ATOX® mills that eliminates unexpected downtime and ensures continuous high performance.
Hi-Chrome Wear Segments
High quality. Re-usable. Recyclable. Hi-Chrome Wear Segments offer a long-lasting, flexible, and environmentally-friendly wear solution for our vertical roller mills.
ATOX® Coal Mill
Our ATOX® Coal Mill has large rollers with great grinding capability of virtually all types of raw coal. The rollers work harmoniously with a highly-efficient separator and feed sluice to consistently and reliably deliver coal meal to your desired fineness and moisture level.
OK™ Raw and Cement Mill
Our best-in-class OK™ Mill is a globally successful vertical roller mill solution for grinding raw material, cement and slag. Its cutting-edge design features consistently deliver the highest quality products with the greatest efficiency. It is affordable to install and cost effective to operate over your cement plant’s lifetime.
OK™ Pro+ Ceramic Wear Segments
Our best-in-class OK™ Mills for raw materials, cement and slag grinding deserve a best-in-class wear liner solution. Our OK Pro+ ceramic wear segments take care of that. By eliminating the risks posed by ill-fitting or substandard third-party solutions, our OK Pro+ wear segments help make sure mill performance continues to meet original specifications.
For reliable grinding capability, our vertical roller mills fit the bill
We have supplied vertical roller mills (VRM) for raw, coal, slag and cement grinding for several decades. The vertical roller mill is well known in the cement and power plant industries as the preferred mill for grinding of raw materials. It is increasingly used as a solution for efficient grinding.
Within the cement industry, vertical roller mills are becoming more important as more cement producers look to increase their use of clinker substitute materials instead of importing clinker to meet localised rises in cement demand.
The advantages of the vertical roller mill include a high level of grinding efficiency combined with reduced energy consumption. For raw materials and cement clinker, the vertical roller mill is an excellent grinding solution because of the relatively lower cost of installation, ease of operation and maintenance, energy efficiency and product quality. Further, our vertical roller mill solution for cement grinding has an ability to dry, grind and separate within a single unit.
Offering you more than just a product
In addition to our innovative equipment offering, we also supply: spare parts, including wear segments, and we provide all aftersales services to help you get the most out of your vertical roller mill throughout its lifetime.
Online condition monitoring services enable you to adopt a proactive maintenance strategy for your OK™ and ATOX® mills that eliminates unexpected downtime and ensures continuous high performance.
We have a long track record in delivering and servicing vertical roller mills throughout the world. With our vertical roller mills, you can reduce energy consumption and achieve reliable high grinding capacity.
Constantly evolving designs
With the many advantages vertical roller mills offer, we continually develop our VRM offering with the latest upgrades, including the OKTM Mill and the ATOX® Coal Mill. The OKTM Mill skilfully comminutes raw material, cement and slag. It features a patented roller and table design and concrete mill stands instead of traditional, heavy steel structures.
The OKTM Mill’s flexible design makes it possible to operate it with a number of rollers out of service while still reaching 60 to 70 percent of the normal operation output, minimising production losses.
The compact and long-lasting ATOX® Coal Mill has the capability to grind virtually all types of raw coal, to your desired fineness. It is suitable for feed materials with varying moisture percentages, handling abrasive and ‘sticky’ raw coal with ease.
Better energy efficiencies
The cement industry’s focus on energy reduction has made vertical roller mills particularly compelling. Grinding systems in cement production make up approximately 85 to 90 percent of total plant electrical energy consumption. As vertical roller mills are 30 to 50 percent more efficient than other grinding solutions, they give cement plant owners a great opportunity to maximise productivity and minimise operating costs. The high energy efficiency is especially beneficial in regions with limited power generating capacity or where electricity availability is limited.
When it comes to grinding raw coal, savings in specific energy consumption can be achieved with vertical roller mills. Specific energy consumption depends on the grindability of the raw coal and the coal meal fineness required. A dynamic separator that ensures high separation efficiency also helps to reduce specific energy use.
Size matter - when you need it to
Capacity requirements for new cement and power plants and grinding units are consistently increasing. Over recent decades, continuous advances in manufacturing processes and design principles have helped us to produce reliable vertical roller mills of ever-larger size and potential capacity.
