Recommended Steel Grit/Shot Blast Media
Key Points:
-
Top quality steel blast media (shot and grit) is critical to the performance of ROBO-BLAST.
-
We provide top quality grit/shot to provide 30X or more recycles before the grit is expelled as dust along with coatings and rust scale. While the cost of steel grit/shot is approx. 4X that of garnet, copper slag, Black Beauty, etc., only 1% by volume is required, therefore an average blast media savings of 95% is achieved!
-
A typical, 35,000 m3 manually blasted tank project requires 80-90 tons of single-use mineral grit (garnet, copper slag, Black Beauty, etc.). The same project using a ROBO-BLAST only requires 1-2 tons of steel grit/shot therefore costs of disposal/ testing/transport of the used grit waste stream is reduced by an average of 95%!
-
Steel grit/shot provides a superior blasted surface for paint and coatings, ensuring longer coating life.
-
Because ROBO-BLAST attaches to surfaces by suction, all dust and debris is vacuumed off during blasting, therefore no compressed air blow-downs or rinsing of surfaces are required. Blasting & Painting can occur at the same time and reduce project schedules by an average of 80%!
GS-25 Steel Grit
Random and angular in shape. Etches/erodes surface. Wear is similar to steel shot, while providing a slightly less smooth surface.
- Hardness: 40-50 Rc
- Size: 0.42-1.0 mm
- Weight: 4800 kg/m3
GS-25
S-330 Steel Shot
Spherical in shape. Does not etch or erode surface as aggressively as steel grit, while providing a smoother surface.
- Hardness: 40-50 Rc
- Size: 0.71-1.19 mm
- Weight: 4800 kg/m3
S-330
S-390 Steel Shot
Spherical in shape. Does not etch or erode surface as aggressively as steel grit, while providing a smoother surface.
- Hardness: 40-50 Rc
- Size: 0.84-1.41 mm
- Weight: 4800 kg/m3
