Jan 01, 2014 · The final step of the cement manufacturing process is the milling. In this step, the clinker is ground together with additives in a cement mill. All cement types contain around 4–5% gypsum to control the setting time of the product. Chemical compounds are used to improve the particle comminution during the grinding of materials (grinding aids).

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.

Clinker is the intermediate product used in the manufacturing of cement. There are two primary processes used to manufacture clinker: the dry process and the wet process. Our plants use the dry process, which is more energy efficient. In the wet process, the raw materials are mixed with water to form slurry, which is fed into a kiln.
