Ever since the roller mill was first introduced to the cement industry, its system capacity has continued to evolve. With the increasing capacity of the mills, the output torque of the gearbox, its main design criterion, had to be increased accordingly (see Fig. 1). These increasing mill sizes have brought the currently used gearbox concepts to

Reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. A reduction gear assembly consists of a set of rotating gears connected to a wheel work. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed.

Common types of grinding mills include Ball Mills and Rod Mills. This includes all rotating mills with heavy grinding media loads. This article focuses on ball and rod mills excluding SAG and AG mills. Although their concepts are very similar, they are not discussed here. Photographs of a glass ended laboratory ball mill show action of ball mass within the mill.
