The cement mill Understanding Cement
Grinding systems are either 'open circuit' or 'closed circuit.' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding. Gypsum is interground with the clinker in order to control the setting properties of the

Cement mill Wikipedia
Closedcircuit systems The efficiency of the early stages of grinding in a ball mill is much greater than that for formation of ultrafine particles, so ball mills operate most efficiently by making a coarse product, the fine fractions of this then being separated, and the coarse part being returned to the mill inlet.

Clinker Grinding Energy Efficiency In Clinker Production
A cement clinker is usually ground using a ball mill. This hardware is generally divided into two or three chambers, with different size of grinding media. As the clinker particles are ground further, smaller media are more efficient at reducing the particle size even further. Grinding can be either ‘open circuit’ or ‘closed circuit’.
