How does a ball mill motor work.Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to .

It should be noted that ball mills are much larger than Attritors and therefore require a special foundation.The Attritor's design accounts for much of the difference: conventional ball mills turn the entire drum or tank containing the media and the material, while Attritors stir the media in a stationary tank with a shaft and attached arms or .
