Q69 Series pass-through steel shot blast machine

This series is a kind of multifunctional steel pretreatment equipment for steel plate and profile steel. The blast wheel is multi-oriented and high-efficient adopting word- advanced unit serpentine curve blades, it could throw high-speed and dense shots, which hiton each position of steel plate in original state, to clean soiled and all-directionally, make rust layers, welding slag, roll scale and feculence on surfaceof steel plate shed quickly and obtain smooth surface with certain roughness, which will improve adhesive strength between the paint film and steel surface, promote fatigue strength and corrosion resistance improve the inherent quality of steel and prolong its use life.
