Abstract

A plant for producing cement, having a first stage for crushing raw material to form raw powder, a second stage for calcination and sintering of the raw powder to form cement clinker, a third stage for cooling the sintered cement clinker, and a fourth stage for crushing the sintered cement clinker to form cement. The first stage for crushing raw material to form raw powder and the fourth stage for crushing the sintered cement clinker to form cement are structurally combined. In this way, during servicing or repair of one crushing stage, the plant need not be shut down because, y variable circuitry switching, the crushing stages permit plant operation with reduced production output.
