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.

where g is m/s 2, R radius of the cylinder (m), r radius of the ball (m), and n c critical speed (rps). The operating speed of the ball mill is kept at 6580% of the critical speed. The lower values are kept for the wet grinding in viscous solution, while a higher value is kept for dry grinding. Burr Mill or Plate Mill
