To calculate grinding media charge for continuous type ball mill, M = 0.000676 x D2 x L 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 قیمت را بگیرید How Can I calculate new ball size and weight . Ball Mill Loading Dry Milling Paul O. Abbe,The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (nonspherical, irregularly shaped and mixedsize media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%15% above the ball charge for total of 23%
