Ball mill trunnions and heads are subject to large alternating stresses during operation. Even though trunnions are designed for infi nite life, there is always a risk of cracks developing due to small casting defects, wear of the inner surface of the trunnion or other damage, such as cutting scars or welding in the highstressed areas.
Make sure the bearing caps are not bolted down. ABOUT THE TRUNNION: Remove all of the bolts as a precaution no need to pull the bearing caps completely off. The mill needs to be jacked high enough to get the last shim in place so that when the mill is lowered onto the shims, it is no longer resting on the bearings.

Trunnion 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. These bearings provide smooth operation and low friction ...
The Metso trunnion liner upgrades originated through this process, offering an old for a new replacement of existing onepiece trunnion liners for a new and improved multipiece trunnion liner configuration. The effectiveness of this design has been tried, tested and proven to improve durability, sustainability and serviceability of the mill ...
To help protect bearings against these extreme conditions and avoid possible production headaches, large amounts of grease are used to purge contaminants from trunnion housings. Help is at hand with SKF trunnion support housings that deliver optimal results: Extend trunnion bearing service life. Reduce maintenance costs. Reduce grease consumption.
A generalized SAG mill power draw equation developed by Austin, is given by: where the parameters used in the model are defined as: mp= net mill power (kW) K = a constant (kW/ton ) D = mill internal diameter (m) L = mill length (m) J = fractional volume of mill filled by total charge. εB = effective porosity of the total charge.
