Feb 13, 2017 Fig. 3. Rubber lining, grate mill. Ball Mill Charge volume. The mill power is approximately directly proportional to the charge volume within the normal range. When calculating a mill 40 charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 are used.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.

Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com- partment. The peripheral wear lining is designed as a lifting or activator plate lining which, with the large balls, achieves a high energy input for comminution. The transfer diaphragm allows.
High ball-to-rock ratios and low overall mill charge levels are now widely used. These practices can result in periodic loss of rock charge and ball-on-liner damage,” said Royston. “Good liner life in aggressive milling environments requires careful mill operation to maintain the mill rock charge and avoid ball-on-liner damage, as well as a.Ball charge is close to 95 kg (209 lb), occupying 34 percent of the mill volume. Balls are used that represent a fully graded charge based on constant wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent ball charge. The drive shaft is torque-metered and records once per second.
