Get A QuoteBall Millsare 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 withball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into themillto be reduced.
