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.
