Metalock's recommendation was to orbitally machine the 1200mm diameter, 600mm long journal and remove sufficient material to clean up the shaft. This was accepted and following removal of 3mm from the diameter, the mill was re-assembled using a new white metal bearing to suit the revised shaft dimension. On site machining capabilities

Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills.. Fig. 24 Attrition ball 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.
Damaged Shaft Repair. Shafts repaired from 80 to 1500mm diameter in any situation (subject to access). Examples include: Ball mill trunnions, Journals on steel making vessels, waste management percolators, ventilator fan shafts, cement …
