Trunnion bearings find wide-ranging applications across various industries, serving as critical components in machinery where rotational motion is essential. In the mining industry, trunnion bearings are integral to the operation of grinding mills and ball mills, where they support the heavy loads and facilitate the grinding of ore or minerals.
Based on the MPT TITAN™ design, the Mills are girth gear & dual pinion driven with self-aligned flanged motors, running on hydrodynamic oil lubricated bearings. The TITAN design enables you to run full process load & 40% Ball charge at 80% critical speed – Max grinding power for every shell size. Standard Mill Types Available: Overflow Ball ...
If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
To ensure smooth and efficient operation, high-quality ball mill bearings can withstand heavy loads and reduce friction during the process. Common ball mill bearings mainly include ball mill trunnion bearings and sliding shoe bearings.
