Steel media is used for bright lustre burnishing and deburring of ferrous and non-ferrous parts for handling purposes where surface refinement is not critical. Steel media is a popular choice in that in that it virtually does not wear.
Corn cob drying media is used in rotary dryers and drum dryers in which, parts can be dried without water spots, cleaned, or polished.
