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. Ball mills may be ...

Ball mills are widely used in mineral processing and chemical industries for particle size reduction. About one third of total electricity energy consumed by them was used to process powder, and almost half of this energy was wasted [1, 2].Their high energy consumption and low milling efficiency are still big challenges [3,4,5].The efficiency of the milling process is highly dependent on load ...

The rotation speed is a key point related to the ball mill efficiency, rotation speed is too great or too small, neither brings a good grinding result. Based on experience, the rotation is usually set between 4-20/minute, if the speed is too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and don't fall.
