It has intercepts 1, 1, ∞. Inverting these values gives us (110), the Miller index of the plane. And the plane in Figure 11.64 c has axial intercepts ∞, ∞, 3. Inverting these values gives us 0, 0, 1 / 3. Clearing the fraction gives us (001), the Miller index. We articulate it as "oh-oh-one.". Figure 11.64 d contains two planes.

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.
