### how to estimate the wear rate for Ball mill - Page 1 of 10

Dec 08, 2009 · Re: how to estimate the wear rate for Ball mill. Hey; Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

### Ball Mill - an overview | ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L: D is, usually, accepted in the range 1.56–1.64.

### A discussion on the measurement of grinding media wear ...

Jul 01, 2016 · The volumetric theory of ball wear states that the wear rate of a ball is proportional to its mass and, therefore, it is also proportional to the cube of its diameter (that is, to its volume). The origin of this theory considers that most comminution events result from impact mechanisms–which do not occur in laboratory mills, given their reduced diameter as compared to industrial mills.

Type “D” Ball and Pebble Mills. One of the most popular designs, the Type D mill is available as a steel ball mill with or without steel plate wear-liners, or as a lined ball or pebble mill utilizing Alumina, Buhrstone or stone linings. Type D ball and pebble mills are available in a variety of standard sizes from 15 inch to 8 foot diameters.

### Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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. A ball mill consists of a hollow cylindrical shell rotati
