The design of a ball mill can vary significantly depending on the size the equipment used to load the starting material feeders and the system for discharging the output product The size of a mill is usually characterized by the ratio “length to diameter” and this ratio most frequently varies from 05 to 35
Principle of grinding Size reduction in a ball mill is purely done by the impact of balls in the cylinder When the mill is rotated the balls are picked up by the mill wall and carried nearly to the top where they break contact with the wall and fall to the bottom to be picked up again
place in ball pebble or rod mills The efficiency of wet grinding can be higher than that for dry grinding but wear of equipment is also higher Usually some form of separation follows size reduction The most common is simple screening in which the screen openings are selected to pass the desired size range and retain material that is too large
The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency a Mill Geometry and Speed – Bond 1954 observed grinding efficiency to be a function of ball mill diameter and established empirical relationships for recommended media size and mill speed that take this factor into account
