Ball Mill

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

Ball Mill Loading

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% ...

Fishing weights as ball mill media

27/08/2009 · 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.

The effect of ball size distribution increased with increasing mill filling and for the mill filling of 35%, the ball size distribution had the maximum effect on the power draw. When the mill charge contained monosized balls, the ball flow regime inside the mill transited to the aracting and impact breakage was the main breakage mechanism.
