Steels Media:

Steel is an excellent grinding media as long as the product can tolerate metal contamination and graying.
It is a high value media because of its low cost, high density, hardness and can be removed from the product stream with a magnet. Balls have a very narrow particle size distribution.

NOTE: Make sure that the steel shot being purchased for use as a grinding media has been manufactured for this specific purpose. Standard off-the-shelf shot will tear up a mill and its screen.

Density 7.6
Hardness: 30 HRC up to 65 HRC

Polymers

Polymers are counter intuitive due to the low density for use as grinding media. However, if the product is low viscosity and shear thinning, it can be quite effective.

Silicas

Silicas are one of the oldest materials for use as a grinding media.  They are still used where low viscosity, low temperatures, low wear rates on equipment and lower costs are required.
