In addition, the low, compact foundation is less sensitive to vibration, which contributes to the continued smooth operation of your ball mill. If the units gear teeth are worn on one side, the symmetrical casing of the MAAG GEAR LGDX Side Drive allows you to flip it over and resume operations from the reverse side of the gearing.
The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and
