Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

Cement Seperator. Application: In cement industry production, in order to improve the efficiency of the grinding system and reduce the energy consumption of the product, a circulating grinding system is now widely used. As an important part of the system, the advanced performance of the classifier directly affects the efficiency of the system.
