In some plants a ball-mill or rod-mill will reduce the ore to, say, 100 mesh and a tube-mill will finish the grinding to 200 mesh or finer. ... The screen is as the discharge end of the mill. Washed oversize is returned to the inside by the action of the mill, and the fine material passes out to be treated. David January 6, 2017; 1:29 pm;
The mill is ideal for crushing wet and sticky ores in one stage. The mill is mechanically sound and will crush to any desired size of ball-mill feed efficiently. Operating cost per unit of actual work is less …
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
One of the most used tumbling mills is the ball mill. This paper reviews different types of grinding media that have been developed and improved over the years and their properties.
