The grinding media is actually alumina particles held in place by an SiO2 glass phase. Sizes from 400 microns to over 1 inch in beads, balls, satellites (ball with bands) and cylinders. Low to medium cost, small sizes are more costly. Fused Zirconium oxide Grinding Media (sp.gr. 3.8) Smooth surface leads to low mill wear and longevity.
Ball end mills produce a radius at the bottom of pockets and slots. Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Flutes Spiral-shaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket.
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.
Ball Mills Discussed Small experimental ball mills can also be completely enclosed in an inert gas glove box. As a consequence, the contamination with Fe-based wear debris can be reduced to less than 12 at. and oxygen and nitrogen contamination to less than 300 ppm.

The difference in the surface roughness produced by the two different mills was attributed to the different breakage mechanism. Shear and compression are the two main mechanisms of comminution in the stainless-steel disc mill, while impact crushing and abrasion predominate in ceramic ball mill (Kratky & Jirout, 2011). Magnesite in the stainless ...
