Coal Slag 180 mesh

Why Choose Coal Slag 180 Mesh for Blasting

Coal slag is a synthetic mineral abrasive produced from coal-fired power plant slag. The 180 mesh grade is one of the finer classifications, suited for applications that demand a light anchor profile and minimal material removal. Its angular particle shape delivers a high cutting speed while the friable nature of the media means it fractures on impact, continuously exposing fresh cutting edges.

This grade is often specified for removing light rust, mill scale, and old coatings from surfaces where a fine finish is required before repainting or coating. It is also used for cleaning softer metals, fiberglass, and composite materials where coarser abrasives would cause warping or excessive pitting.

Typical Applications for 180 Mesh Coal Slag

• Fine surface preparation: Creating a light anchor profile on metal substrates before liquid coating or powder coating.
• Delicate substrate blasting: Cleaning aluminum, thin-gauge steel, fiberglass, and composites without dimensional damage.
• Coating removal: Stripping thin layers of paint, lacquer, or light rust from industrial equipment and structural components.
• Outdoor blasting: Suitable for open-air blasting operations where expendable media is preferred over recyclable grit.

Handling and Selection Tips

When selecting coal slag 180 mesh, consider your blast nozzle size, air pressure, and desired surface profile. Finer mesh sizes flow differently through metering valves compared to coarse grades. Always confirm that your blast pot, hoses, and nozzles are rated for fine abrasives to avoid clogging or inconsistent feed.

Store coal slag in a dry, covered area. Moisture absorption can cause clumping, which disrupts media flow and reduces blasting efficiency. If you are transitioning from a coarser grade, purge the blast system thoroughly to prevent cross-contamination that could affect your surface finish.
