Substitution Several abrasive agents may be used as substitutes for silica sand during sandblasting. Some of the abrasives studied are steel grit, specular hematite, nickel slag, copper slag, crushed glass, garnet, staurolite, olivine, and coal slag. Most of these abrasives work as well as silica sand and cost about the same or even less. However, the use of a substitute may have other ...

 · Coal Slag is generally used in a pressure or siphon blaster when paint, rust, and scale have to be removed from steel, such as car/truck frames, tanks, heavy machinery, farm equipment, etc. Coal slag is superior to silica because it contains or less silica. Coal slag is moisture free and will not pack or absorb moisture. Coal slag is generally used once and is not recommended for use in a ...

Wet abrasive blasting (also known as vapor abrasive blasting) removes coatings, contaminants, corrosion and residues from hard surfaces. It's similar to dry sand blasting, except that the blast media is moistened prior to impacting the surface.
