30kw Compressed Air Operated Double-Sides Automatic Sand Blasting Machine
Specialized surface treatment equipment designed for high-efficiency, uniform sand blasting of both sides of thin metal sheets and products in a single operation.
Core Capabilities
  • Dual-side Synchronous Blasting: Both upper and lower sides feature identical blasting guns operating synchronously, ensuring consistent surface roughness, cleanliness, and texture without secondary cleaning
  • Precise Parameter Control: Adjustable blasting pressure (0.2-0.8 MPa), abrasive flow rate (50-200 kg/h), conveyor speed (0.5-5 m/min), and nozzle swing frequency (0-30 times/min) via PLC
  • Intelligent Automatic Operation: PLC control enables automatic feeding, positioning, blasting, dust removal, and discharging
  • High Abrasive Recycling Rate: Cyclone + pulse dust collector system achieves up to 90% abrasive recycling, separating reusable abrasives from impurities for cost savings and environmental benefits
