Cement fineness. Closed circuit cement mill by A.Sen

Closed circuit cement mill. The strength development of concrete is the result of the chemical reaction of water with cement particles. The reaction always starts at the surface of the cement particles. Thus larger the surface available for reaction, greater is the rate of hydration and strength development.

Control of a Closed Circuit Cement Mill ScienceDirect

1972-6-1  CONCLUSIONS Several models of a closed circuit cement mill have been illustrated. A method of on-line estimation of the point of instability of the mill has been derived and a control al­gorithm to hold the mill at a desired distance from this point has been developed. This control algorithm is yet to be used in practice.

The cement mill

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.
