Bond Ball Mill Index Test | JKTech,The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.
Jyoti Ceramic Industries Pvt. Ltd.,Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks. Formula to be used is M = 0.000929 x D2 x L D = 180 - 10 = 170 cms L = 180 - 10 = 170 cms Therefore M = 0.000929 x (170)2 x 170 Grinding media quantity = 4564 kgs.
