Aug 21, 2021 The optimum mill speed increases with the charge volume, as increased weight of charge reduces the amount of cataracting taking place. Ball mills are often operated at higher speed than rod mills, so that the larger balls cataract and impact on the ore particles.
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.
Aug 23, 2021 Here we list 17 signs to mention you that the ball mill is running and needs to be checked in. Find the abnormal signs early is very important to prolong the ball mill service life. 1. The sign of swollen belly . Just like a bloated stomach, if the amount of grinding exceeds the maximum capacity and discharge capacity, it will cause the mill.
The starting point for ball mill media and liquid charging is generally 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 45 to 50 above the ball charge for total of 58.
