Read More8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 11.5 times the shell diameter Figure 8.11. The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight.

Read MoreThe Milling Process Definitions Cutting speedv c Indicates the surface speed at which the cutting edge machines the workpiece. Effective or true cutting speed v e Indicates the surface speed at the effective diameter DC ap.This value is necessary for determining the true cutting data at the actual depth of cut a p.This is a particularly important value when using round insert cutters .
Read MoreApr 29 2017 In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity then since the velocity may be considered as constant for all the balls in the mill the work done by a ball is proportional to its weight. Since the amount of ore crushed varies as the work done upon it it seems .
