This machine is a high-efficiency, continuous surface treatment equipment specially designed for cleaning, derusting, and stress-relieving LPG steel cylinders before painting/coating. It adopts a monorail overhead hanger conveying system, enabling automatic, continuous, and all-round shot blasting for cylinders.

1. Surface Cleaning & Derusting
   • Removes oxide scale, rust, welding scars, and dirt from cylinder surfaces efficiently.
   • Achieves surface cleanliness up to Sa2.5–Sa3 (ISO 8501-1).
   • Creates a uniform rough surface to enhance paint/coating adhesion.
2. Mechanical Performance Enhancement
   • Relieves residual stress from welding and heat treatment.
   • Improves cylinder fatigue strength and corrosion resistance.
3. Production Efficiency
   • Continuous monorail conveying: 200–500 cylinders/hour (model-dependent).
   • Fully automated operation: reduces manual intervention and labor costs.
4. Environmental Protection
   • Closed-loop dust removal system: controls dust emission, meets environmental standards.
   • Abrasive recycling: lowers consumption and operating costs.
5. Applicable Workpieces
   • Standard LPG cylinders: 12kg, 15kg, 50kg (Φ320–Φ680mm, height 600–1800mm).
   • Other steel cylinders/bottles with similar dimensions.

• Monorail Hanger System: Overhead monorail with automatic hanging/loading/unloading; cylinders rotate during blasting for 360° coverage.
• High-Efficiency Turbines: Direct-drive, linear-blade turbines with high projection speed and density.
• Abrasive Recycling: Closed-loop system (elevator, separator, screw conveyor) for continuous reuse.
• Dust Control: Multi-stage filtration ensures low emissions and clean working environment.
• Safety & Automation: Interlocked doors, emergency stop, fault detection, and remote monitoring.
