Product DescriptionProduct DescriptionOur products having been produced strictly according to the ISO9001:2015 quality standard and are mainly used in mines, cement plants, building materials, power stations, chemical industry and steel mills, Well sold across China and exported to the United States, Chile, the UK, Brazil, South Africa, Australia, South Korea, India, Russia, Mexico, Malaysia, Laos, Vietnam and other dozens of countries and regions, our products got highly appreciated by our customers.Diameter tolerance and roundnessDiameter30405060708090100110Tolerance(mm)±2+3,-2+4,-3Roundness(%)≤2≤3≤4Our products having been produced strictly according to the ISO9001:2015 quality standard and are mainly used in mines, cement plants, building materials, power stations, chemical industry and steel mills, Well sold across China and exported to the United States, Chile, the UK, Brazil, South Africa, Australia, South Korea, India, Russia, Mexico, Malaysia, Laos, Vietnam and other dozens of countries and regions, our products got highly appreciated by our customers.(1)Smooth surface: A smooth surface is a characteristic produced by forging technology, with no defects in the surface of the ball, nor deformation or out of roundness. This amplifies the grinding effect of the balls on the ore for an optimum performance.(2)Internal tightness:Since these balls are forged from round bar steel, internal and external deviations, are non-existent. Forged balls have a high internal density and high fine particle degree, which enhances the drop resistance and the impact toughness of these balls, thus vastly reducing the breakage rate of a forged balls.(3)Suitable for wet grinding: Our forged balls are comprised of high-quality alloy steel, together with new efficient anti-wear materials, independently developed by our company. By matching the alloying element with rare elements, and by controlling the chromium content, the corrosion resistance of the balls is greatly improved; during wet grinding procedures, trivalent chromium oxide, forms a protective oxide film of chromium and iron which hinders the breakage of the ball and/or eases the reincorporation of the detached particles to the film itself. As mines commonly use a wet grinding process, this forged ball becomes even more suitable. (4)In SAG Mill operations:Large balls with a diameter of 125-150mm not only reduces unit consumption, but also increases handling capacity.
