Brand NameGUAN WANG Supply Ability50000Ton per year PackagingBag or steel drum Delivery TimeWithin 30days UsageThe GUAN WANG High Chromium Alloyed Cast Grinding Ball is widely used in cement building materials, metal mining, coal paste thermal power plants, chemical engineering, ceramic coating, lightindustry, magnetic materials. Our grinding ball has the characterisitic of high hardness, good wear resistance and low breakage. The surface hardness and the wear resistant of the grinding ball will further enhance during the operation process. At the same time, it also can increase the production capacity of the mill machine and improve the surface area of cement and the recovery percent of the ore.Chemical Composition(%)CSiMnCrPS2.4-3.20.5-0.80.5-0.810.0-11.0≤0.1 ≤0.1Mechanical PropertiesHardness(HRC)Toughness without North AK(J/cm2)The break rate%Impact fatique lifetime of the droping ball≥56≥4≤18000MicrostructureM + C (M-Martensite C-Carbide) Applied areasGrinding for metallurgical,mines, power stations, cement plants Actual consumption of ballsHigh hardness ore 300-450g/ton Coalhigh ash content 50-100 g/ton Medium hardness ore 200-300 g/ton Coallow ash content 20-50g/ton Low hardness ore 50-200 g/ton Cement 10-50 g/ton Remark: the above specification can be changed according to the customer`s demand.
