Pumice Grit 30/60 mesh

Lightweight Mineral Cleaning Grit for Industrial Blasting

Pumice Grit 30/60 mesh is a naturally occurring, highly angular, lightweight abrasive. Its low bulk density and moderate hardness make it an excellent choice for cleaning sensitive substrates, removing light rust, scale, and surface deposits, and preparing surfaces for coating or bonding. The 30/60 mesh particle size distribution provides a balanced combination of cleaning speed and surface finish uniformity.

Unlike heavier metallic or mineral abrasives, pumice grit imparts minimal residual stress to the workpiece. It is commonly used in air blasting and wheel blasting equipment where controlled material removal is required. The media is chemically inert, non-toxic, and free of crystalline silica, making it a safer alternative for many industrial cleaning operations.

Typical Industrial Applications

• Precision cleaning: Removes light oxidation, carbon deposits, and surface stains from machined components, molds, and dies without dimensional change.
• Surface preparation: Prepares aluminum, brass, copper, and other non-ferrous metals for painting, anodizing, or adhesive bonding.
• Textile and stone finishing: Used in the denim finishing industry and for achieving matte finishes on natural stone and glass.
• Electronics and aerospace: Suitable for delicate cleaning tasks where substrate integrity must be preserved.

Selection and Handling Guidance

When specifying Pumice Grit 30/60 mesh, consider your blasting pressure, nozzle distance, and desired surface finish. The friable nature of pumice means it fractures upon impact, continuously exposing fresh cutting edges. This self-sharpening characteristic provides consistent performance but also generates dust; adequate dust collection is recommended. The media can be recycled a limited number of times depending on blast pressure and impact angle. For optimal results, consult with our team about your specific blasting parameters.
