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 …

When the ball mill is running, impact vibration occurs, and a great impact sound is generated, and the wear between the tooth surfaces is aggravated. Vibration caused by the displacement of the transmission parts. After the ball mill works for a long time, the anchor bolts of the motor, reducer and pinion bearing seat in the transmission …

The axial thrust bearing, located on the gearbox input pinion shaft, carries the combined axial force (in a forward direction towards the GT) from the single helical gear train end thrust and that resulting from the cold prestretch of the high-speed coupling shaft. ... Ball mill diameter = 4.57 m (inside liner diameter = 4.39 m) Ball mill load ...

Adding more coal to the process changes the load of the mill but the ball charge stays constant. The amount of ball charge in the mill is a function of the condition of the mill liners. The mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear.

The pinion is a small gear with a matching tooth profile to the ring gear on the ball mill. From a bearing point of view, there are two bearings at the end of the shaft on the pinion and there are ...

Solution: replace the pinion of the ball mill, add two anchor bolts on the inner side of the pinion and the meshing side of the big gear, and reinforce the base again. After the operation, the ...
