Trunnion Bearing Assembly Ball Mill & Rod Mill
Ball Mill PINION SHAFT BEARINGS. Pinion shaft bearings are of the SKF anti-friction type mounted in a common twin bearing assembly. Bearings are fixed in place so that the pinion shaft of the mill is always in alignment with the drive components. V-belt driven mills are furnished with an outboard bearing of similar construction.
Ball Mill Maintenance & Installation Procedure
If everything is clear, the mill can be run for from six to eight hours, observing any abnormal reactions at the trunnion bearings, pinion bearings, and gear and pinion mesh. It should be noted that with an empty mill the reactions and operating characteristics of the bearings and gearing at this point are somewhat different than when operating with a ball or rod charge.
