Grinding Cylpebs

Application of grinding cylpebs: mainly used for mining industry, cement plant, power station, etc. 
Abrasion: about (30-60) g/t in cement.Grinding Cylpebs

Features and Advantages of Grinding cylpebs:
With stable quality, high production efficiency, high hardness, wear-resistant, the volumetric hardness of the grinding cylpebs is between 60-63HRC, the breakage is less than 0.5%. The organization of the grinding cylpebs is compact, the hardness is constant from the inner to the surface. Now has extensively used in the cement industry, the wear rate is about 30g-60g per Ton cement.
