The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11).The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.


The pulp weight in the mill is obtained by subtracting the mill weight during the test from the empty mill weight, including the ball charge, at the start of the test. How to Decide the Quantity of Grinding Media-FAQs. In a 54" x 60" Steel Ball Mill, for example, the difference between the weight of a one-third and one-half ball charge is ...


The starting point for ball mill media and liquid charging is generally 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 45% to 50% above the ball charge for total of 58% ...


Aug 18, 2019· The ball mill ball ratio should be judged according to the effective length of the mill, whether it is equipped with roller press, feed size, lining material and structure, and the number of rotation speed. After installing the ball mill, ball mill size gears need to be meshed and the amount of processing is also gradually increasing.


Aug 27, 2009· Posted 28 August 2009 - 12:26 PM. Check the other "Ball Mill Media" threads here. Pure lead is too soft, and you'll get significant wear (and contamination of your BP with Lead). Use an alloy of lead that contains Antimony (preferred) or Tin. I'm pretty sure fishing weights are almost pure Lead.
