Steel structure shot blasting machine is an industrial equipment used to remove rust layers and oxide scales on the surface of steel. It is mainly used for rust removal and strengthening treatment of steel structural components in fields such as bridges, ships, construction, machine tool beds, grid structures, engineering machinery, and bridge manufacturing. The equipment achieves uniform and consistent metallic luster on the surface of steel through strong shot blasting, improving the quality of coating and anti-corrosion effect. The dust removal and shot supply system consists of a three-stage pulse filter cartridge dust collector and an air controlled shot supply gate valve. The motor speed is controlled by a frequency converter to ensure smooth operation. The pellet circulation system includes a screw conveyor and a full curtain separator to achieve automatic recycling and reuse of steel pellets. With the implementation of environmental protection policies, this equipment is gradually replacing the pickling process and will develop towards intelligent remote monitoring and customized solutions in the future
