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: Matching blasting nozzles are installed on the top and bottom sides and run synchronously. This delivers uniform surface roughness, cleanliness and surface finish across workpieces, eliminating the need for follow-up secondary cleaning procedures.
- Precise Parameter Control:Controlled by PLC, key operational parameters are fully adjustable: blasting pressure ranges from 0.2 to 0.8 MPa, abrasive flow rate from 50 to 200 kg per hour, conveyor speed between 0.5 and 5 m/min, and nozzle swing frequency from 0 to 30 cycles per minute.
- Intelligent Automatic Operation: The PLC control system realizes automated execution of the whole production workflow, including workpiece feeding, positioning, blasting treatment, dust extraction and finished part discharging.
- High Abrasive Recycling Rate: Combining a cyclone separator with a pulse dust collector, the system attains an abrasive recycling rate as high as 90%. It separates usable abrasives from contaminants, cutting operational costs while meeting environmental protection requirements.

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
