raw material milling cement

Millingand grinding ofraw material, minerals andcementis a rough process, with highly abrasive and hard feedmaterialsthat can accelerate equipment wear and tear. This leads to increased costs for equipment and spare parts replacement, and costly maintenance.

6.Raw material mill. This takes places in vertical steelmill, which grinds thematerialthrough the pressure exerted by three conical rollers. Which roll over a turningmillingtable. Horizontal mills, inside which thematerialis pulverized by means of steel balls, are also used in this phase.

Ball Mill Ball millswith high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills.
