Cement manufacturing brief description of a cement mill

Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

How Portland Cement is Made? Manufacturing Process of

In the next state of the process, clinker is cooled in coolers. The hot air from the coolers is returned to the preheater in order to save fuel in the overall process. The clinker is then ground to produce portland cement. Gypsum is added during the grinding process to control the set rate of the cement.
