Bond Work Index Formula-Equation

See this useful summary Table of Bond Work Index by Minerals For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um The sample was received crushed appropriately for the ball mill testBall 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 you are designing forJKTech Laboratory Services,For every Bond Ball Mill Work Index test carried out at JKTech, a standard report is issued The report details the The report details the Bond test procedure method, and presents the results including F80, P80, Grindability and Work Index
