• The bearings of the gear reducer (failures on input bearings are the most common) have a life time of down to 3 to 4 years mainly reduced due to the starting 'stress' . The change of the bearings is linked to a major overhaul. • The life time of gear reducers are not matching the life time expectations of the mill and need to be replaced.

The Texrope drive employs a driven sheave mounted between the outboard bearing and one of the bearings adjacent to the pinion. The driving sheave is mounted directly on the motor shaft. Such a drive is flexible and economical both in initial cost and in maintenance, repair and replacement. ... Rubber regrind mill liners are an obvious solution ...

The ball mill is 13-ft-6-in diameter by 18-ft, and was originally intended for a rod mill application. It has a large diameter trunnion and an oversized motor. To bring the ball mill speed up to 75% of critical from 66%, the 24-tooth pinion was replaced with a 27-tooth one. Equipment selection using SPI data was deemed a success.

Wear of pinion bearings There is a double row spherical roller bearing on both sides of the pinion bearing. After a period of use, the bearing parts wear out, the gap between the inner ring, the outer ring and the roller increases, and radial runout occurs when the pinion shaft rotates, which will cause the gear tip clearance to change ...
