The cement mill Understanding Cement

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. The drum is generally divided into two or three chambers,

High Performance Cements and Advanced Ordinary Portland

If High Energy Milling (HEM) is applied for the grinding of cement, this can lead to substantial refinement (< 2 µm) and mechanically activation of the powder particles that in conventional material exhibit a particle size in the order of 50 µm. Earlier work and preliminary studies have shown that this can result in a faster setting
