Description

Technical Field

[0001] The utility model relates to the technical field of cement clinker crushing, in particular to a cement clinker crushing device. Background Art

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay and iron raw materials in appropriate proportions, burning them until they are partially or completely melted, and cooling them. In the cement industry, the most commonly used silicate cement clinker has the main chemical components of calcium oxide, silicon dioxide and a small amount of aluminum oxide and iron oxide. The main mineral components are tricalcium silicate, dicalcium silicate, tricalcium aluminate and tetracalcium aluminoferrite.

[0003] The size of cement clinker entering the mill is the main factor affecting the mill output. If the size of the material entering the mill is large, more large balls must be added to the first chamber of the mill to crush the material. The larger the size of the material entering the mill, the lower the mill output and the greater the power consumption. The mill output is inversely proportional to the fourth root of the size of the material entering the mill. The smaller the feed size, the higher the mill output and the lower the energy consumption; on the contrary, the output decreases and the energy consumption increases. Therefore, the utility model proposes a cement clinker crushing device. Utility Model Content
