The equations describing the movement of the trunnion points of the ball mill are derived. The stressstrain state of the trunnion of the ball mill was determined depending on the temperature of the inner and outer surfaces of the trunnion. Deformations and stresses arising on the surface of a pin are investigated by numerical methods.

The ball mill trunnion is located at both ends of the ball mill cylinder and plays the role of supporting and connecting the mill cylinder. 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.
