The application of vertical roller mills (VRMs) for ore grinding is a part of the strategies against rising energy consumption (Reichert et al., 2015). The VRM technology was introduced in the mid'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill.
OZ Minerals explained in the study: "Vertical roller mills are widely used in the grinding of cement plant feeds and products, slag, coal and other industrial minerals, with thousands currently in operation worldwide. The mill has benefits in reducing power consumption by circa15%, no ball charge grinding media, higher flotation recovery and ...
Vertical roller mills have a lower specific energy consumption than tumbling mills and require less space per unit and capacity at lower investment costs. Vertical roller mills are developed to work as airswept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius ...
The modular design of the vertical roller mill comprising 4 to 6 grinding rollers allows the continuation of mill operation even if one roller module is not available. The same applies to the innovative multi drive design of the mill drive consisting of up to 6 identical drive units in the range of 2,000 kW each.

the mill include but are not limited to side and face milling, fly cutting, and precision boring. Mills are classified on the basis of the position of their spindle. The spindle Operates in either a vertical or horizontal position. The amount of horsepower the mill is able to supply to the cutter is also often important.
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. The ...
