To prevent racing and excessive wear end-liners for ball mills are furnished with integral radial ribs or with replaceable lifters or with both. When a grate discharge is used the grates and wear plates are normally perpendicular to the mill axis while the discharge pans conform to the slope of the mill head.
wear to the mill lining. The mill's direction of rotation can be changed simply with a switch so that wear on the liner is distrib-uted equally from both sides. Shorter maintenance time for mills Simple control of the inching and creeping modes lets you quickly set up mill mainte-nance procedures without endangering employee safety.
Wear-resistant material is selected for use because it's less prone to mechanical failure over time than other materials. It won't pit or fracture when it's repeatedly loaded and unloaded, even at capacity. So you can bet that any part made from wear-resistant material will last longer than one manufactured from non-wear-resistant material.
