grinding capacity. The more roll pairs the mill has, the greater the size reduction it can achieve. The rolls typically have a castiron core with a 5⁄ 8 to 3⁄ 4inchthick outer layer made of alloy steel. The outer layer's surface is typically corrugated with grooves or other patterns, depending on the application. For some
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.
The gas flow and drying capacity was normally decreased with mill size (grinding capacity). In other mills like vertical roller mills both grinding and drying take place together inside the mill by the hot gases supplied through the mill. The vertical roller mills are usually designed to have a rather constant ratio between airflow and grinding ...
