Cement ball mill is a cement grinding machine used in the cement production line for cement clinker grinding. AGICO supplies the cement ball mills for processing limestone, cement clinker, gypsum, slag, ore, etc.

Cement ball mill started in the 1960s, after the ball mill has been enlarged, the conditions have been created for reducing construction investment and production cost and improving labor productivity, which makes the ball mill process widely used in large scaled cement manufacturing plant.

The ball charge typically occupies around 30%-36% of the volume of the mill, depending on the mill motor power and desired energy consumption and production rates.

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 ...
