THE OPTIMAL BALL DIAMETER IN A MILL. Let us look back at the optimal ball charge in a mill. The necessary number of balls having the definite diameter N b in a mill should be proportional to grain number N having the definite diameters which they can grind N b ~ N. (7) The number of grains of the material with determined diameters depends on the grain size distribution.

Aug 23, 2021 High temperature of the ball mill will affact the efficiency 3 For every 1 increase in moisture, the output of the ball mill will be reduced by 8 -10 . 4 when the moisture is greater than 5 , the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons.
Aug 10, 2020 Ball mills are a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using a ball mill.

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.
