As the "power heart" of the shot blasting machine, the impeller assembly achieves efficient surface treatment (rust removal, descaling, strengthening, etc.) by projecting steel shots at a high speed of 70-100m/s. It is suitable for batch processing of large-sized or high-hardness workpieces such as castings, automotive parts, and heavy steel structures. Its performance directly determines the equipment capacity and process quality, and is one of the core competitiveness of the surface treatment industry.
Functional and performance advantages
1 High-efficiency blasting capability
Shot blasting volume: 300-1200kg/min continuously adjustable, suitable for all scenarios from fine cleaning (steel shot Φ0.2mm) to heavy rust removal (steel sand Φ2.5mm).
Precise coverage: Through the impeller inclination angle (adjustable from 15° to 45°) and blade surface optimization, the surface roughness (Sa) of the workpiece is controlled within the range of 2.5-12.5μm.
2 Power transmission innovation
Direct motor design: cancel the traditional belt/chain drive, adopt flange direct connection + spline shaft structure, transmission efficiency> 95%, energy consumption reduced by 20%.
Intelligent speed regulation: support variable frequency motor (IP55 protection level) stepless speed regulation (800-3500 RPM), accurately matching different workpiece hardness and process strength.
3 Extremely long service life
Impeller body life: high chromium cast iron + anti-fatigue design, continuous operation life ≥ 5000 hours, twice as long as ordinary cast iron impeller.
Economy of blades: Symmetrical wear design + reversible use, a single set of blades can process up to 80-120 tons of workpieces, and the overall cost is reduced by 40%.
Comparative advantages in the industry
Efficiency benchmark
1200kg/min shot blasting volume is 1.3 times that of the same specification model, and it only takes 90 seconds to process automobile chassis parts (50kg).
Maintenance cost
Modular quick-release design + long-life material, the average annual maintenance cost is 50% lower than that of traditional impellers.
Process compatibility
By adjusting the speed and shot blasting volume, it meets strict standards such as SAE J2277 (surface cleaning) to AMS 2430 (shot peening).

Operation and maintenance guide
Blade Replacement Conditions
Wear threshold:Single-side wear > 10mm, or pits/cracks with a depth > 3mm on the surface.
Operational recommendations
Replace in groups (8 pieces synchronously) to ensure dynamic balance, and the replacement time is < 30 minutes. Clean the back of the blade before flipping it for use to avoid eccentric vibration caused by residual projectiles.
