Professional China High Chrome Grinding Media - Ball Mill High Chromium Alloy Casted Grinding Ball – EASFUN

Diameter：φ15-120mm

Application: It is widely used in various mines, cement plants, power plants and chemical industries.

Chromium forged balls are widely used in powder preparation, and ultra-fine powdering of cement, metal ores and coal slurries. They are used in thermal power, chemical engineering, ceramic paint, light industry, papermaking and magnetic material industries, besides others. Forged grinding balls have excellent toughness, preserve their circular shape, low wear and tear, and a low crushing rate. The hardness of our high chromium ball product is 56–62 HRC, the hardness of medium chromium ball is up to 47–55 HRC, while the hardness of the low chromium ball is up to 45–52 HRC, with 15 mm as the minimum and 120 mm as the maximum diameter. It is widely used in a variety of dry mills.
