The shot blasting machine removes rust, cleans surfaces, and strengthens surface properties by propelling high-velocity abrasive shots at the workpiece surface. Its core operating principle is as follows:

I. Core Workflow

Conveying and Ejection

The workpiece is conveyed into the blast cleaning chamber via an adjustable-speed roller conveyor, where it is subjected to intensive shot blasting from multi-angle nozzles, rapidly removing scale, rust, and surface contaminants.
The shot blaster features a high-efficiency impeller design with adjustable shot flow, enabling it to meet diverse surface roughness requirements.

Pellet circulation

The scattered shot media is conveyed via a longitudinal screw conveyor and an elevator into the separator, where dust and foreign matter are filtered out, allowing the purified shot media to be recirculated.
The dust collection system purifies the air using pulse-jet cartridge filters, with emission levels below the industry’s regulatory limits.

Automated Control

Integrated PLC system supports one-button start-up and continuous operation, with safety interlocks to ensure operational safety.
II. Functions of Key Components
Cleaning Chamber: Large-capacity plate-type structure with double-layer wear-resistant manganese steel protective plates for easy maintenance.
Conveying system: sprocket-and-chain-driven roller conveyor with smooth transmission and an interlock mechanism equipped with protective devices.
Shot blaster: multi-angle arrangement for high-efficiency blasting, enhancing surface adhesion.
Dust collection system: pulse-jet cartridge filter, compact in size and highly efficient.
III. Application Scenarios
