What is the typical reason a ball mill trunnion needs to be replaced unexpectedly? It is unclear if the trunnion damage was known ahead of time and planned for a change-out during the shell reline or if it was discovered during the reline work. While, not knowing if this is the feed or discharge end trunnion, there ...
Data on ball charges for Ball-Rod Mills are listed in Table 5. Further information regarding grinding balls is included in Table 6. ... Self-aligning main trunnion bearings on large mills are sealed and internally flood-lubricated. Replaceable mill trunnions. Pinion shaft bearings are self-aligning, roller bearing type, enclosed in dust …
On a 11'-6" x 22'-0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill. System monitors including pressure switches and flow monitors are provided, along …
The ball mill will be equipped with different ball mill bearing systems based on its scale and work requirements. The most common ones are trunnion bearings and sliding shoe bearings, which correspond to trunnion bearing ball mills and sliding shoe bearing ball mills, respectively. Both types of ball mills have wide applications and …
