Commonly used equipment in cement plants are:

1. In the firing workshop: coal pre-homogenization equipment, coal mill, rotor scale, preheater, rotary kiln, cooler, etc.

2. Cement workshop: cement mixing, roller press, cement mill, packaging machine, etc.

3. Raw meal workshop: limestone crusher (hammer crusher, jaw crusher, etc.), stacker and reclaimer for limestone pre-homogenization, raw meal mill.

4. Various metering belts, belt conveyors, fans, and circulating water systems.

The production process of cement is usually summarized as two grinding and one firing, which is divided into three stages: calcareous raw materials, clay raw materials and a small amount of calibration raw materials are crushed, mixed in a certain proportion, finely ground and blended into raw materials with suitable composition and uniform quality. , Is called raw meal preparation; the process of calcining the raw meal in the cement kiln to partially melt the Portland cement clinker with calcium silicate as the main component is called clinker calcination; adding appropriate amount of gypsum to the clinker and mixing The materials or admixtures are ground into cement together and packaged or shipped in bulk, which is called cement grinding and leaving the factory.
