Grinding Beads
Product introduction:
The dry grinding of ball mill requires high quality of aluminum ball.In the case of the same alumina content, the quality evaluation criteria of high aluminum grinding balls are generally abrasion and density.In terms of wear, wet grinding with liquid medium is added, in the wear relative to dry grinding requirements are not very high, the ordinary wear of about 1/10,000 is enough to apply, but the dry grinding of high aluminum grinding ball wear requirements are relatively high, now on the market of high aluminum grinding ball according to my understanding of about 0.4-0.8, should choose these low wear ball;In terms of density, most of the balls now have a density of 3.60, which is not a problem for wet grinding.The dry wear has less water to cushion, the impact on the ball is very large.So the probability of breaking the ball is very high.Therefore, high-alumina grinding balls with higher density, such as 3.65, are very suitable for dry grinding. Although the density is only increased by 0.5, the impact resistance of the ball is greatly increased.
