• ### Mill Steel Charge Volume Calculation

Jun 19, 2015 We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below or approximated from the equation and calculation Steel Charge Loading in Mill

• ### How To Estimate The Wear Rate For Ball Mill Page 1 Of 10

Dec 08, 2009 Re how to estimate the wear rate for Ball mill. Hey Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

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. So as a rule of thumb we use 25 solid loading.

• ### Optimization Of Continuous Ball Mills Used For Finish

The LD ratio of the ball mill was varied in four steps of 1.75, 2.1, 2.79 and 3.49, and the ball charge filling ratio was varied in three steps of 15, 20 and 25. The experiments clearly indicated that the optimal LD ratio and the optimal ball charge filling ratio are different for each feed fineness.
