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.

Diamond grinding method uses a close network of diamond saw blades that graze away uneven concrete bits. The blade runs on surface many times to ensure smooth surface. These grinders lead to a longitudinal finish on macroscopic level. This longitudinal texture provides safe ride, skid resistance and lesser noise.
