grinding media charging in ball mill

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.

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 (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.

Grinding Media Growth Steel

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput. Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising operational cost.

Choosing the Best Media Mill For Your Wet Grinding Application

Jul 01, 2003· Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes.
