Casting Grinding Ball
Casting grinding balls are a type of grinding media that are used in ball mills for mining, cement and mine industries. They are made of low-chromium cast steel and have different diameters ranging from 50.8 mm to 88.9 mm. Casting grinding balls have high hardness, good wear resistance, no breakage and even wearing. They are produced by metal mold casting, which is a cost-effective and low-investment method. Casting grinding balls can improve the grinding efficiency and reduce the energy consumption of the mills.
