Grinding and Classification Circuit

 · Ore from the belt feeder enters a 10′-6″dia. x 13′-0″ ball mill, which grinds the -5/8" ore to 70% minus 200 mesh. Barren solution is added to the ball mill to produce a slurry of 60% solids. The solids content of the ball mill discharge is controlled by a ratio control loop, whereby barren solution addition is proportional to the ...

Ball Mill

8.3.2.2 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 1–1.5 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.
