Choosing the Right Blast Media for Abrasive Blasting

Coal Slag Coal slag is by-product of coal-burning power plants, considered a “green” abrasive because it would otherwise be disposed of as waste. It is a relatively cheap, low dusting abrasive with low free silica, but is considered a dirty abrasive and not widely used in wet abrasive blasting because the high amount of “fines” (fine particles) mud up on the surface.
