The Mill Trunnion Liner fits inside the bearing to protect it from wear caused by the ore being washed over the liner and through the bearing as it is fed to or discharged from the mill.. The difference in the trunnions at each end of the mill isn't in the trunnions themselves. The trunnion liner on the feed end of the mill may have a WORM to assist the ore into the mill.

As is well known, trunnion bearing play a crucial role in ensuring the efficient and reliable operation of cement plants. The use of ball mill trunnion in cement mills is because they enable the mills to operate smoothly and economically. These bearings are also able to withstand the abrasion from the grinding materials used in the cement production process.

trunnion and the bronze bushing of a hydrostatic bearing. The lack of lubrication was originated by a logic failure which allowed the mill to start and run over the trunnion bearing bushing without the lubrication system to be turned on, that is, without oil film. The logic failure was caused by an operator fault.

A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for …

A SAG (Semi-Autogenous Grinding) mill is a giant rotating cylinder filled with grinding media and the ore being reduced. As the mill rotates, the grinding media lifts and the impact crushes the feed material. SAG mill control refers to the practice of managing the mill load, which is the amount of material inside the mill at any given time.

Thus, with condition monitoring of the SAG mill behaviors employing vibration, acoustic and thermal signals, the relevant parameter can be diagnosed and monitored. ...

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.

Ball Mill Trunnion Bearing Lube System View Larger Image 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.

Low Pressure /High Flow oil is circulated from a reservoir to the top of the Trunnion bearing. The low pressure oil coats the journal and other bearings surfaces, helping with oil wedge formation when rotation has been achieved. The high flow circuit will deliver the filtered and cooled oil to the bearing. LIFT & LUBE SYSTEMS
