Abrasive sand

Introduction
Every waterjet cutting operation using abrasive generates a slurry of spent garnet, fine metal particles, and water that settles in the cutting tank. Without an automated removal system, this sludge must be manually shovelled out — a time-consuming and physically demanding process. WAMIT abrasive removal systems automate the extraction, saving hours of labour per week and keeping the tank at the correct water level for consistent cutting performance.
System Types
| Type | How It Works |
| Screw conveyor (auger) | Rotating auger moves settled abrasive to a collection bin outside the tank. |
| Vacuum pump system | Motorised vacuum lifts abrasive slurry to a settlement tank. |
| Drag conveyor | Chain-driven flights sweep the tank floor continuously. |
Key Benefits
- Reduces manual cleaning from 2–4 hours/week to under 30 minutes
- Maintains consistent tank water level — critical for accurate Z-axis height sensing
- Reduces operator back-injury risk from manual shovelling
- Garnet collected in one bin for easy disposal or recycling
- Timer-controlled automatic cycles — runs during breaks or overnight
