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 as P80 and maximum and finally the type of circuit open/closed Capacity (25% of total) Total Volume WET Working Capacity (60% of total) rpm DRY milling 60% of critical Gear Pinnion Drive used on Larger Mills JH 32014 Talk with the Experts sales@pauloabbe pauloabbe Since 1911 phone 6303503012 fax 6302387584 BAALLLL MMIILLSLLSBall Mill Capacity Dimensions 2013 Paul O AbbeDec 12, 2016 Ball Mill Power Calculation Example A wet grinding ball mill in 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 Ball Mill Design/Power CalculationThe sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates from different sources are widely divergent It is especially difficult to teach mill Calculate Ball Mill Grinding Capacityhow to calculate ball mill capacity Calculation Of Cement Ball Mill Capacity – Stone Crusher how to calculate capacity of ball mill – Mining Ball Mill Design, Ball Mill Sizing,Design Of Ball Mill Run of mine hardness, broken grain degrees size, grid sieve hole, ball mill type, steel ball Capacity Calculation Of Ball Mill
