Read MoreWe can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charg.
Read MoreOne can increase the weight of the charge by increasing the number of balls or by using a ball material of high density. Optimum grinding conditions are obtained when the volume of the balls is equal to 50 percent that of the ball mill. So the variation in the weight

Read MoreFor achieving maximum capacity of the ball mill the ball charge should be equal to about percent of the ball mill volume. 1 . For removal of very small amounts of precipitate from large volume of water the most suitable filter is the filter.
Read Moreball mill power is affected by steel ball load the sensitivity of detection signal is low 5. Seriously affected by the revolving speed of ball mill elevator abrasion and the granularity distribution inside ball mill the air pressure method is hardly popularized 6.
Read MoreThe effects of percent solids mill loading and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44- m −325-mesh material reached maximum at 70 solids whereas the ball wear decreased as pulp .
