Industrial Overview
Selecting the correct abrasive media is the most critical decision in determining the "Cost per Square Meter" of an industrial blasting project. While **Garnet** is the world standard for expendable, high-performance blasting, **Steel Grit** dominates the high-recyclability sector in enclosed facilities.
What is Garnet?
Garnet is a natural gemstone abrasive. It is chemically inert, low-dusting, and provides a sharp angular profile. Ideal for "once-through" open blasting in shipyards and refineries.
What is Steel Grit?
Steel Grit is a manufactured metallic abrasive. It is extremely hard and engineered for high recyclability (up to 200+ times). Mandatory for automatic blast rooms and heavy steel fabrication.
Technical Comparison Table
| Feature | Almandine Garnet | Angular Steel Grit |
|---|---|---|
| Hardness (Mohs) | 7.5 - 8.0 | 8.0 - 9.0 |
| Recyclability | 3-5 Times | 200+ Times |
| Dust Generation | Very Low | Zero (Metallic) |
| Surface Finish | Sharp, Uniform Sa 3.0 | Deep, Aggressive Anchor |
| Nozzle Wear | Moderate | High (Requires B4C) |
| Disposal Cost | Low (Inert) | N/A (Recycled) |
Garnet Logic
- Best for ship hull open blasting.
- Lower setup cost (no recovery floor).
- Superior for stainless steel (no carbon contamination).
Steel Grit Logic
- Mandatory for Automatic Blast Rooms.
- Lowest long-term cost due to recycling.
- Fastest cleaning rate on heavy scale.
