Manufacturer Sandblasting Media Green Garnet Omphacite 20/40 mesh
20/40 mesh Green Garnet Omphacite is a premium natural blasting media professionally produced for industrial heavy-duty sandblasting and surface treatment applications. As a high-hardness, low-dust eco-friendly abrasive, it is refined from high-quality omphacite garnet ore through multi-stage washing, drying, crushing and precise mesh classification, ensuring pure texture, stable particle shape and consistent granularity for long-lasting and uniform blasting performance.

Featuring a Mohs hardness of 7.5 to 8.0 and outstanding particle toughness, this 20/40 mesh green garnet provides strong cutting force and efficient rust removal, scale cleaning and surface profiling. Its unique dense crystal structure resists excessive crushing during blasting, effectively reducing material consumption and improving construction efficiency. Different from traditional quartz sand and brown abrasives, it contains zero free silica, eliminating silicosis risks and fully complying with global industrial safety and environmental protection standards.
The standard 20/40 coarse-to-medium mesh size is the most versatile specification for large-area blasting projects. It can thoroughly remove rust, old paint, oxide layers and welding spatter on steel structures, ships, containers and mechanical equipment, forming a uniform matte surface without excessive surface damage. With low dust emission and excellent fluidity, it ensures a clean working environment and stable blasting effect.
Directly supplied by the manufacturer, this green omphacite garnet features stable quality, high purity and cost-effective pricing. It is a highly reliable blasting media widely adopted in marine engineering, petrochemical, construction and machinery manufacturing industries.
