19.06.2015We 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.

Compared with traditional ball mills, the grinding efficiency of the vibration ball mill is increased by 2-5 times and the energy consumption is reduced by 20% – 30%. Vibratory ball mills use high-frequency vibration to make grinding media in the cylinder produce inertial impact force. Raw materials are ground under the impact.
