The cement production process can usually be briefly summarized as "two grinding and one firing", that is, the raw materials are first ground into raw materials, then the mature materials are calcined, and then the clinker is ground into cement. From the sandstone library, limestone library, steel slag library, fly ash library fixed ratio dosing system mixed into raw material powder, the conveying system sends the raw material powder into the raw meal mill for raw meal preparation, and the prepared raw meal is sent to the homogenization library. The raw meal quantitative feeder in the homogenization storehouse sends the raw meal to the preheater for preheating and then enters the rotary kiln system to calcinate the mature material. After calcination, the clinker can be sent to the finished product mill to grind into finished cement after being cooled and broken.
