Ball MillDesign/Power CalculationLinkedIn.Ball Mill Design/Power CalculationLinkedIn. 2016-12-12 ·Ball Mill Power CalculationExample. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350.

Grate Discharge millswill not face this issue. C) This value represents the Volumetric Fractional Filling of the Voids in between the balls by the retained slurry in themill charge. As defined, this value should never exceed 100%, but in some cases – particularly inGrate Discharge Mills– it could be lower than 100%.

Ball Mill Power CalculationExample #1. Awet grinding ball millin closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).

Thepower calculatedon using equation 1, (Bond, 1961;Rowlandand Kjos, 1978), relates to: 1)Rod milling– arod millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit. 2)Ball milling– aball millwith a diameter of 2.44 meters, inside new liners,grinding wetin open circuit.

Themillproduct can either be finished size ready for processing, or an intermediate size ready for finalgrindingin arod mill, ballmillor pebblemill. AG/SAGmillscan accomplish the same size reduction work as two or three stages of crushing and screening, arod mill, and some or all of the work of a ballmill.

Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as2″ feedand making a product as fine as35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

Rod millsare very similar to ballmills, except they use longrodsforgrindingmedia. Therodsgrind the ore by tumbling within the themill, similar to thegrindingballs in a ballmill. To prevent the conditions leading torodcharge tangling, the length to diameter ratio is maintained at 1.4 to 1.6.
