Cast grinding balls are suitable for ball mill with a diameter of ~3 m. In the ball mill with a diameter less than ~ 3m, the grinding effect of cast ball is slightly better than that of forged. Because the acceptable impact value of cast grinding ball is only 2~4 joules, cast ball can withstand the impact in the small diameter of ball mill.
