The Mills are available in wide range of capacity for all ... Coal Mill UM Series 2 Rollers 3 Rollers UMseries Coal Mill Models with details of structural dimension, product throughputs and
Mediumspeed mill. Mediumspeed mills are smaller than lowspeed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.
They are also ideal for grinding coal with low hardness, such as lignite and subbituminous coal. Vertical Roller Mills. Vertical roller mills are a newer type of coal grinding mill and are characterized by their higher grinding efficiency, reduced maintenance requirements, and higher drying capacity. They use a rotating table to crush and ...
