Oct 01, 1985· CONCLUSION Decreasing the size of the lifters in a ball mill from cm to cm causes the rate of feed disappearance, kl, to increase. This is prob ably due to the larger height available for the balls to cataract and cascade when the lifters are smaller. This may also be the reason for higher specific power, P/Mp, when the mill ...

The overall design of ball mills and rod mills are compact, with simple operation and easy maintenance. But the both are different in performance and applications. In this article, the similarities and differences between ball mills and rod mills are analyzed from 9 aspects, and suggest how to choose ball mill or rod mill.

In ball milling, the desired particle size is achieved by controlling the time, applied energy, and the size and density of the grinding media. The optimal milling occurs at a critical speed. Ball mills can operate in either a wet or dry state. While milling without any added liquid is commonplace, adding water or other liquids can produce the ...
