The shot blasting machine operates with an adjustable speed conveyor roller controlled by electric power, transporting steel workpieces or steel projectile bodies to the blasting area within the cleaning machine room. The entire workpiece surface is impacted and friction-treated by intensive projectiles from multiple coordinate orientations, effectively removing oxide scale, rust, and surface contaminants. This process creates a uniform roughness and smooth steel surface while maintaining structural integrity.

At the entrance and exit points, roller systems efficiently load and unload workpieces. The spent projectiles, dust, and rust particles are systematically purged through ventilation systems. The resulting shot-dust mixture is transported via screw conveyors to the chamber funnel, where vertical and horizontal screw conveyors consolidate the material below the elevator. The purified projectiles are then elevated to the separator for recycling, while dust generated during the cleaning process is directed to the dust removal system for environmental compliance.

This steel plate shot blasting cleaning machine is specifically designed for roller-type blast cleaning applications. It serves critical functions in building construction, bridge infrastructure, and other industrial sectors requiring large I-beam and H-beam steel structure surface preparation. The machine effectively eliminates surface rust and prepares high-stress structural components for further processing or coating applications.
