Cement Plant Production Process

Mined limestone is transported by conveyors to the crusher for crushing. Crushed limestone is ground by ball mill or vertical mill into powder, and then transported by conveyor to the raw material silo for storage and further mixing. After homogenization, raw material goes into the preheating system for decomposition. The decomposition rate is about 95%. After calcined in the rotary kiln, raw material becomes clinker. Clinker, gypsum, and other mixed materials are ground in ball mill into cement of qualified fineness. Powder separator is used to adjust fineness of cement to achieve energy-saving production. Packaging machine and automatic loading machine are used to pack and deliver bags of cement.
