The mill trunnion bearings are a key assembly in mill operation. If the trunnion bearings are not reliable the complete mill is not reliable. Various trunnion bearings designs are used, ranging from fully hydrodynamic to fully hydrostatic. The design charge load defined earlier is a direct input in the calculation of the trunnion bearing pressure.
The overflow type of Ball Mill is designed to overflow and discharge materials from the trunnion on the outlet side. By combining it with a mechanical classifier or wetprocessing cyclone, you are able to extensively use this type for grinding in closed circuit or for special applications such as regrinding in open circuit.
The first part of the mill that we will look at is the TRUNNION BEARING. This is a HYDROSTATIC BEARING which is a slow moving bearing that carries a heavy load. Usually it is constructed from Babbitt's metal.

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.
The ball mill trunnion is a special type of steel casting, which is a key component in the ball mill. It plays the role of supporting and connecting the ball mill cylinder and is also a passage for raw materials.

A ball mill is one of the most common equipment items in a mineral processing plant. Its job, to grind rock by tumbling it in a large metal cylinder loaded with steel balls, is highly energy intensive. ... slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge trunnion.
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.

Ball mills and conventional milling equipment are both used to grind materials into smaller pieces. Ball bills can handle materials like ore, ceramics, and paint, whereas conventional milling machines can handle huge ...
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.
