The through-type shot blasting machine is a piece of equipment used for the continuous removal of scale, cleaning, and pre-treatment of various steel materials. It efficiently processes steel plates, steel bars, steel beams, section steel, steel pipes, and cast steel parts. The machine operates by continuously working without interruption, featuring a cleaning chamber with a large capacity box-shaped welded structure, as well as an indoor conveying roller track for loading and unloading materials. The through-type shot blasting machine is easy to operate; simply load the steel materials onto the machine, press the start button, and after a short cycle, the system automatically discharges the processed materials, completing the entire cleaning process and removing all dust and residual shot.
