High Purity River Garnet Sand Abrasives Sand 80Mesh Garnet Sand for Rust Removal
1. Garnet Introduction
Garnet abrasive is most generally used as a high-performance blast media, for the cleaning of aluminum and fiberglass structures. Because it is an inert, non-toxic, naturally occurring mineral, garnet abrasive is also used in places where water contamination is a concern, such as dry docks, bridges, and harbors.
2. Garnet Specifications

3. Garnet General advantages
Extremely hard (8 MOH Hardness) blast abrasive
Very low dust generation
Recyclable up to 5 times
Used for Dry Blasting, Slurry Blasting, and predominately the predominate media for Waterjet
Available in grit sizes of including 80 & 30x60 to #120 (2-4 mil profile)
Lower consumption rates as compared to conventional abrasives
By recycling and lowering lbs/sq.ft. consumed, greatly reduces abrasive cost and waste
< .5% Free Silica
4. Garnet Characteristics
| Color | Type | Mohs Hardness | Production Process | Applications | Available Sizes |
| Dark brown color garnet sand | Rock sand. | 8.0 | Crushing and washing process. | Sandblasting, rust removal, Water filtration, etc. | 8-14#,10-20#,16-20#,20-40#,30-60#,80# |
| Brown color garnet sand (Red) | Rock sand | 7.5-8.0 | Crushing and washing process. We wash rock sand up to 6 times. So it’s of high purity. | Sandblasting, rust removal with low conductivity, water filtration, etc. | 8-14#,10-20#,16-20#,20-40#,30-60#,80#,120# |
| Pink color garnet sand (light) | River sand | 7.5-8.0 | alluvial garnet sand was scouring and washing by river water. It is Cleaner and with less sharp edges than rock sand. | Sandblasting, water jet cutting with less blocking in nozzles. | 10-20#,20-40#,30-60#,80# |
| Pink-red color garnet sand | Sea sand, | 8.0 | It is alluvial garnet sand. The sand source was formed by the ancient rock near the sea. So it’s very clean and with high purity. | Especially for water jet cutting without blocking in nozzles. | 60#,80# |
5. Garnet Applications
Garnet Abrasive has the following benefits for almost all applications.
Clean – Garnet abrasive creates less dust than most other abrasives, making it suitable for use in confined spaces like tanks.
Cost-Effective – Garnet abrasive is so effective that lower volumes overall are required for most jobs and last a long time.
Garnet Abrasive is a reusable media and can be reused several times under the right conditions. It does break down quicker than fully reusable abrasives such as aluminum oxide grit.
Optimum Surface Clarity – garnet abrasives results in a superior surface for coating.
Environmentally Friendly – Garnet is non-toxic and inert, making it safe for use around bodies of water. It is also easy to clean, while its durability reduces the formation of dust.
