An impact crusher uses impact force to crush materials. This crusher of cement operates by picking up the raw materials and throwing them against a hard surface or impact plate, causing them to break into smaller pieces. Impact crushers are often used for crushing softer materials, such as limestone, gypsum, and clay.
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.
