# How Can Be Measured The Diameter Of Ball Mill Calculation Pdf

Feed size is usually 189 inch or less product size ranges from 500181 to below 5181. Ball mills work well on hard, brittle materials. They are not as suitable for grinding elastic, ductile or fibrous materials, or for fine grinding in general. Ball mills can blend and grind at the same time, yielding a fine, intimate mixture.
