Coal Slag 20 mesh

Understanding Coal Slag 20 Mesh for Blasting

Coal slag is a by-product of coal-fired power generation, processed into a hard, angular abrasive with a consistent particle size distribution. The 20 mesh grade is a medium-coarse grit that balances cleaning speed with surface profile. It is widely used in outdoor blasting where containment and recycling are not practical, and the abrasive can be expended after a single use.

This material is valued for its low free-silica content compared to silica sand, making it a safer alternative for operators when proper respiratory protection and environmental controls are in place. Its angular shape provides an aggressive cut, while the density ensures good impact energy transfer to the workpiece.

Typical Applications

• Structural steel preparation: Removing mill scale and rust before painting.
• Shipyard and marine blasting: Hull cleaning and maintenance in open environments.
• Concrete surface profiling: Roughening surfaces for overlay or coating adhesion.
• Tank and pipeline exteriors: External corrosion removal and coating preparation.
• General fabrication: Pre-paint preparation in workshops without media recovery systems.
