Garnet Sand Blasting
Top garnet sand grades which are used in sand blasting surface smoothing, listed below
Garnet Grades:
Size Range (mesh) | Size Range (mm) | Ref. Name |
garnet 12/24 mesh | .710 – 0.850 | |
garnet 20/40 mesh | 0.425 – 0.850 | |
garnet 30/60 mesh | 0.250 – 0.600 | |
garnet 40/100 mesh | 0.150 – 0.425 | #70 |
garnet 50/100 mesh | 0.150 – 0.300 | #80 |
garnet 50/200 mesh | 0.075 – 0.300 | #120 |
All garnets do not yield the same profile, cutting speed, and recycling ability.
The harder, full crystal garnets (Almandite) will generally yield faster cutting speeds and lower dust levels than the more friable, fractured garnets (Andradite).
Garnet Sand for Blasting
In the process of surface preparation, Garnet sand is blasted on to the surface of the steel with the use of high pressure compressed air. This process helps in extending the life of the coating. It is used for oil firms, petrochemical tank works, offshore applications, pipelines, heavy machinery repair, industrial parts cleaning, and shipbuilding companies, as abrasive.
Sand blasting is a machine that uses abrasive garnet with air pressure to clean or prepare surfaces for painting or other coatings. Sand blasting machine can also be used for the destruction of sand, it is also used to remove contaminated substances from metal products, these have been cast or made forged and in some cases have been welded. The media is put in a tank and air pressure is kept under the same pressure as the operator will do sandblasting. The media is then dropped by gravity into a blast hose line, which pushes it out of the blast nozzle, which is the pressure of the air we use.
