A trunnion (from Old French trognon 'trunk') [1] is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. [2] Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion ...

WhatsApp: +86 188380728291. If a person is looking for a higher load machine where the surface area is restricted, Trunnion Bearings works the best. However, in the case of selfaligning and compressive loads, Slide Shoe Bearings are the bestsuited ball mill bearings. 2. Trunnion Ball Mill Bearings are widely used in many industries due to their popularity owing from ...
WhatsApp: +86 18838072829The 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.
WhatsApp: +86 18838072829Ball Mill Trunnion Bearing also known as the ball mill trunnion, is an important part of the ball mill that carries the rotation of the cylinder of the ball mill.

WhatsApp: +86 18838072829The 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.
WhatsApp: +86 18838072829Trunnion bearing ball mills are a type of ball mill characterized by their use of trunnion bearings, which are large cylindrical bearings encased in housings that support the mill's rotating components. The trunnion bearing is installed at the periphery of the ball mill trunnion.
WhatsApp: +86 18838072829The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
WhatsApp: +86 18838072829Two 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.

WhatsApp: +86 18838072829Depending upon available handling facilities, the head or shell can be lined separately ina repair bay, or alter assembly of the mill proper in the trunnion bearings. In the case of ball mills, all internal wearing parts will pass through the manhole, whereas in the case of open end rod mills they sill pass through the discharge trunnion opening.
WhatsApp: +86 18838072829Crushed 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.
