I Ball mill maintenance
A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill''s inside surface and eventually tumble down to the bottom. The raw material is fed into the ball

Simulation assisted capacity improvement of cement grinding
The ball mill modelling approach for two-chamber dry grinding mill is a perfect tool for the cement grinding modelling. By mill inside sampling the breakage rate is separately calculated from the discharge function. Ball size adjustment was the major optimization for the capacity improvement for that case study.

OPTIMIZATION OF CEMENT GRINDING OPERATION IN BALL MILLS
Operation and Elements of a Closed-Circuit Ball Mill System . Cement ball mills typically have two grinding chambers. The first chamber is filled with larger diameter grinding media andlined with lifting liners . The first chamber coarse-grinds the feed material and prepares it for the second chamber. The second chamber is the fine grinding
