The cyclone preheating system Phase IV: Calcination. The calcination is the core phase of the cement making dry process. The calcination of the preheated raw meal takes place in the rotary kiln of the cement plant. The rotary kiln is a huge rotating furnace in which the raw meal is heated up to 1450 ⁰C and turned to clinker.

Sand, fly ash, cement, and other materials are elevated to the storage silo at one time, and then weighed, batched, and mixed until the concrete is made. This type is characterized by reasonable process flow, high productivity, but a large investment. The storage silo and mixer of the double-stair concrete plants are roughly at the same elevation.
