When fine grinding is the main method, the protrusion of the liner is relatively small, the pushing effect on the grinding body is weak, the impact is small, and the grinding effect is strong, so the liner is required to have good wear resistance. The Alloy Steel Ball Mill Liner is capable of withstanding massive impact forces.

A ball mill liner is a type of material that is placed inside a ball mill to protect the mill from wear and tear. The liner acts as a barrier between the grinding media and the material being processed, preventing excessive wear and damage to the mill. Ball mill liners also serve to contain the grinding media and prevent it from spilling out of ...

Then in ballwear formula (25), T = /K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = /Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/ are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.
