How Is Cement Produced in Cement Plants | Cement …
The working principle of a ball mill. The cement ball mill is a horizontal cylinder filled with steel balls or other grinding media. Inside the cylinder, the steel balls are rotated and tumbled and crush the clinker into very fine powders, which are product cement powders. During the grinding process, a small percentage of gypsum is added to ...
What Are the Parts of a Cement Mills?
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, …
