mill bearing assembly and drive unit Shell-supported ball mills are becoming the mills of choice over those with trunnion bearings. Depending on the size of the mill, there are two, four or six sliding shoes per bearing assembly. The expected bearing load determines whether hydrostatically or hydrodynamically lubricated bearing shoes are used.

For large mills, using 125 to 140 mm (5 to 5-1/2 in.) feed ball size, conventional new lifter-liner dimensions are around 300 to 350 mm (12 to 14 in.) overall height above the shell, with around 100 mm (4 in.) plate thickness and around 150 mm (6 in.) top width. Detailed design depends on individual mill circumstances. Increasing lifter height usually leads to increased shell liner wear …
