Sandblasting machines are the "drivers" of surface treatment. Fueled by high-pressure air (or water) from compressors, they channel energy through pressure tanks (for stable mixing) and wear-resistant nozzles (like boron carbide) to deliver kinetic force to abrasives. Whether large-scale pressure-tank systems or precision-focused suction guns, every design ensures abrasives perform at their best: high-speed ejection (50-100m/s), steady trajectories, and smart mixing controls to avoid waste.
Steel Grit and shot are the "tools" that get the job done, each with unique traits to match needs:
- Steel grit (angular, HRC 55-65): Acts like a "cutting force" under high pressure (0.6-0.8MPa), stripping thick rust/oxide and roughening surfaces—ideal for coating prep on bridges or ships.
- Steel Shot (spherical, HRC 40-50): Works as a "precision finisher" at moderate pressure (~0.5MPa), removing thin rust/oil via "rolling impact" while strengthening parts (e.g., springs, gears) for longer life.
Their true strength? Perfect matching. Machines adapt to abrasives, and abrasives thrive on machine settings:
- Coarse grit (e.g., G18) pairs with ≥8mm nozzles to avoid clogs; fine shot (e.g., S110) uses 5-6mm nozzles for uniformity.
- Grit (less fluid) relies on pressure-tank systems to prevent jams; shot (smooth-flowing) works with both pressure and suction setups.
- Recovery systems recycle unworn abrasives (especially durable shot), cutting costs and boosting sustainability.
Together, they deliver 30% better coating adhesion, 50% longer part fatigue life, and doubled efficiency. Choose this duo, and elevate your surface treatment to industrial excellence—where quality, speed, and value converge.
