Smaller sizes offered.

Highest density material available for milling applications. Available as small pellets (not spherical), satellites (balls with bands) and round balls. Cost, medium to high, varies with roundness and size.

Various alloys available (low carbon, high carbon, chrome steel, stainless steel, etc.) in a variety of forms:

The first of the “engineered” class of grinding media, glass beads (small balls) and balls were developed specifically for grinding applications where sand wasn’t available.
