Ball Mill - an overview | ScienceDirect Topics
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.
TiC Coated Bearing Balls - BryCoat Inc.
About TiC Coated Bearing Balls: Steel balls – typically 440C. Coated with thin film of TiC (Titanium Carbide) ceramic. Hard and inert surface layer. Low friction surface.

Bal-tec - Ball Material Selection
Ball screws are very similar to ball bearings in that they generally use either chrome steel or type 440C hard stainless steel. A peculiarity of ball screws is that they typically have a load ball and the next ball is a .001-inch undersized spacer ball, and so on. One half of the balls are load balls and one half are spacer balls. Exotic ...
