## Size Reduction Equipment Paul O Abbé

Size Reduction Tumbling Steel Ball Mills and Ceramic Lined Mills are one of the most precise, reliable and cost effective methods of fine grinding solids in either a wet or dry stateBall Mills are referred to by many names including Pebble Mills, Tube Mills and Attrition Mills, but no matter what the nomenclature they all operate on the same efficient principle

## Ball Mill Design/Power Calculation

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size
