    the starting point for ball mill media and solids charging generally starts as follows: 50% media charge; assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size 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% to 25% product loading. so as a rule of thumb we use 25%

    Ball Mill Loading - Wet Milling - Paul O. Abbe

    charging a wet mill – the general operation of a grinding mill is to have the product impacted between the balls as they tumble. unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product. as with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other.
