Another technology that breaks particles under compression is the Loesche Vertical Roller Mill. The VRM can achieve high reduction ratios, reducing particle sizes to below 45 μm. A study conducted on Platreef ore compared the energy requirements of the VRM to ball milling from size reduction from a P 80 of 12 mm to a P 80 of 45 μm . The VRM ...

Vertical roller mills (VRM) contain a series of rollers that press down on a layer of particles on a circular table, either flat or grooved. ... Reducing the ball size will increase throughput due to providing more surface area at the cost of higher media wear rate. Increasing the ball load improves the power draw and throughput.

Introduction. Vertical roller mill (VRM) is a type of heavyduty and energyintensive grinding equipment for many industries, such as cement, steel and chemical industries. It is used to grind slag, nonmetallic ore and other block and granular raw materials into required powder materials. The fine powders can be used as raw materials for cement ...

Capacity of cement new production lines has steadily increased over the last years. Reduction of investment costs is one of the most important driving factors for this trend. Because of simple scalability and low energy consumption, the vertical roller mill is a key part for single mill cement lines. The limits of material throughput of VRMs are, unlike other mill types, not defined by the ...

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.

In conclusion, the application of vertical roller mill technology in the cement industry has revolutionized the way cement is produced. VRMs are more energyefficient, ecofriendly, and produce a more consistent product compared to traditional grinding mills. They are also more suitable for use in urban areas due to their lower noise level.
