Product Description

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

Double-sides automatic sand blasting machine processing thin metal sheets

Typical Applications

This equipment is widely used for surface treatment of stainless steel sheets across multiple industries:

Kitchenware and Sanitary Ware Industry: Stainless steel kitchen cabinets, sinks, range hood panels, bathroom mirrors, and shower room frames
Building Decoration Industry: Stainless steel decorative panels, curtain wall panels, elevator car panels, and handrails
Home Appliance Manufacturing: Surface roughening treatment of stainless steel shells for refrigerators, washing machines, microwave ovens, and water heaters
Automotive and Aerospace Industry: Surface cleaning and roughening of stainless steel structural parts, exhaust system components, and aircraft interior panels
Electronic and Electrical Industry: Surface treatment of stainless steel shells for precision electronic instruments, switch cabinets, and distribution boxes
