After exiting the cement kiln, the clinker is cooled and stored. To produce cement, clinker is mixed with a small amount of gypsum and other additives, such as pozzolans or slag. This mixture is then ground in the cement ball mill. The grinding process involves passing the clinker and additives through the rotating drum of the ball mill, …

A ball mill liner is a type of material that is placed inside a ball mill to protect the mill from wear and tear. The liner acts as a barrier between the grinding media and the material being processed, preventing excessive wear and damage to the mill. Ball mill liners also serve to contain the grinding media and prevent it from spilling out of ...
