However, in the production of high chromium cast iron cast grinding ball, the low hardness and impact toughness of the grinding ball lead to the problems of the high rate of breakage and wear dia50mm grinding balls for coal mills in shanxi and the united states are mainly used for grinding hard anthracite coal the ball must have high wear.In recent years, forged grinding balls are used widely because of its plenty of advantages, like high toughness, smooth surface, good wear-resistance and impact resistance, low breakage and lost round rate. shandong iraeta is capable of manufacturing forged grinding balls with dia.
It won't crack and lose circularity easily. 1) high hardness: huamin forged grinding media steel ball has high hardness: surface hardness can reach to 55-67 hrc, volume hardness 56-64 hrc 2) high impact toughness: impact toughness is more than 12 j / cm2. 3) low broken rate: peel fragmentation resistance property of over .Maximizing wear resistance of balls for grinding of coal . 10, a pilotplant ball mill, with a 0.01 m 3 chamber, was used to perform wear tests, comparing the original ball material and seven grades of high chromium cast irons, grinding the same coal as used in the industrial.
Most of the grinding balls for sag mill have a diameter of 120-150mm, and the larger diameter have a larger gravitational potential energy to impact and grind.based on the operational principle of sag mill, it require the grinding ball must have excellent impact resistance and wear resistance.good toughness could greatly enhance the grinding.Oct 18, the life of inferior commercial balls was increased five to six times by a laboratory tempering heat treatment. for balls that did not break, the major impact wear mode was spoiling and ranged from an average rate of 0.28 to 4.46 mg per impact. the softest balls (steel) had excellent impact resistance but low abrasion.
