Grinding balls for mining precision balls for ball mill
AISI steel grinding balls for ball mill appli ions typically have a tolerance of ±0.05/±0.10 and a density of 7.70 to 7.95. Exceptions include Al series 1XXX and Al 6061 which have the same tolerance but a density of 2.71 and 2.70 respectively and TCK 20/TCK 30 balls with a higher density of 14.85.
7 Differences Between Ball Mill and Rod Mill -
The cylinder length-diameter ratio of rod mill is generally 1.5-2.0 while the cylinder length-diameter ratio of ball mill is smaller only slightly greater than 1. In addition the cylinder speed of the rod mill is lower than that of the ball mill so the grinding medium works in the cascading state. 2. Discharging way of ball mill and rod mill
