The equipment is used forHSurface cleaning of section steel, suitable for mass production in large-scale manufacturing enterprises, utilizing roller conveyors to transport the section steel into a shot blasting room for rust removal treatment. The main chamber in the image is for installing the shot blaster, with the equipment designed for8Twin-tower shot blasting machine, with two at the top, two on each side, and two at the bottom, capable of evenly covering and cleaning H-beams; roller conveyor type shot blasting machine for large-size H-beams.HHigh-section steel structural components are stress-relieved and surface-rusted cleaned. The roller conveyor through-type shot blasting machine transports steel structural components or steel into the blasting chamber via a variable-speed roller conveyor controlled electrically during the cleaning process. All surfaces are struck and abraded by a dense stream of high-velocity shots from various directional coordinates, causing the oxidation scale, rust, and dirt to rapidly dislodge. The steel surface is left smooth with a certain degree of roughness. Workpieces are loaded and unloaded at the inlets and outlets on both sides of the cleaning chamber. The shots and rust dust that fall onto the steel are swept up by a blowing device, and the mixture of shot and dust is conveyed to the hopper of the chamber by a recovery spiral. It is then collected by a longitudinal and transverse screw conveyor and lifted to the separator at the top of the machine. The clean shots fall into the separator hopper for reuse in the blasting cycle. Dust generated during the shot blasting process is channeled to the dust collection system through exhaust pipes, where it is purified and the clean air is released into the atmosphere, while the particulate dust is captured and collected.
