Polishing and drying media are important process aids, for achieving consistent mass finishing results.
Stainless steel balls, ballcones or satellites, and stainless steel pins are used for burnishing and deburring ferrous and non-ferrous parts. Corn cob drying media is used in rotary dryers and drum dryers in which parts can be dried without water spots, cleaned, or polished. Glass beads are also used for polishing. Anti-adhesion balls are used to prevent flat, thin parts from sticking together.
