Two ball mill trunnions are installed at both ends of a ball mill, one is the feed trunnion, which is the passage for the material to be transported into the cylinder, and the other is the discharge trunnion, through which the ground material is sent out. The trunnion bearing supports the ball mill trunnion and drives the trunnion to rotate.

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.
The ball mills are rotary equipment used in mining plants in grinding, which uses steel balls to reduce the particle size of the ore as shown in Fig. 1. The rotating assembly of the mill is supported by two bearings, called trunnion bearings indicated in Fig. 2. The bearings are static components having bushings, on which the mill rotates.
