The equipment of ball mill used in cement plant includes vertical cement mill, roller press and ball mill, etc. The cement ball mill in cement plant is usually divided into 2-4 silos, the most representative of which are the "new type of high fineness cement ball mill" and "open flow high fineness cement ball mill".
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.); when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, the …
The cement industry recognizes its responsibility to manage the environmental impact, associated with the manufacturing of its product. Mainly, there are two types of cement production process; such as wet process and dry process. The preparation of cement includes mining, crushing, and grinding of raw materials, calcining the materials in 1408
