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.
Coal mill is the main equipment in the pulverized coal preparation process.Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the …
