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.
Ball-nosed endmills are typically more common in most smaller shops and cost less. Using a ball-nosed endmill comes at the price of decreased speed and depth of cut. On a vertical milling machine, the ball-nosed endmill will mean that the cut has to be made from the top down. This will require the barrel to have additional support underneath.
