The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3. Table 1-11 The Relation between Steel Ball Diameter and Material Size
A particle size distribution indicates the percentage of particles of a certain size (or in a certain size interval). These intervals are also called size classes or fractions. A simple example is shown below. Here, a mixture of grinding balls has been separated by size: 5 mm, 10 mm, 15 mm and 40 mm: 5 mm. 10 mm.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
r2, where r is the distance measured perpendicularly from the rotation axis. The evaluation of this integral for various of cases of interest is a common exercise in multi-variable calculus. In most of our problems we will only be using a few basic geometrical shapes, and the moments of inertia for these are given in Figure 1.2 and in Figure 1.3.
'generate' the shape of the lens into the blank, getting close to its final shape, size, and curvature. Although an outdated process, one generation technique that is still used today is loose abrasive grinding. This involves using various grit sizes mixed with water (this mixture is called a slurry) to remove glass.
