MODELLING OF CEMENT GRINDING CIRCUITS FOR PREDICTIVE CONTROL

Predictive control of cement processes including the grinding circuits has been reviewed by S´nchez and Rodellar (1996). Studies of resia dence time distribution for the transport of charge through continuous ball mills have concluded that neither ideal mixed flow nor plug flow can model the transport satisfactorily (Austin et al., 1984).

Cement grinding unit, or called cement grinding plant, cement grinding station is an individual step in the cement production line.The new-type cement grinding units adopt pre-grinding technology. The cement grinding units not only reduce the particles of feeding materials, but also help to produce cracks and flaws inside the particles, which largely increase the production …

Cement Grinding - Mineral Processing & Metallurgy

A typical raw mix consists of 75-85% limestone, 12-25% shale, the balance consisting of silica or quartzite and iron oxide. Exact proportioning is dependent upon their chemical properties before and after calcining to cement clinker. For good kiln practice the grind required is 88-92% – 200 mesh for standard cement, 99%-200 mesh for high early.
