In essence, cement is a fine powder. The main feature of the powder mass is that, when interacting with water, it gradually begins to harden. The process of interaction between the two components (cement and water) is completed by the formation of a solid array, similar in hardness to natural stone.

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.
