The hook-type shot blasting machine uses two hooks to load workpieces alternately into the shot blasting cleaning room. The shot blaster is used to throw 0.2~0.8 projectiles to the surface of the workpiece, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to increase its service life. This model is widely used for surface cleaning or strengthening treatment of medium and small castings and forgings in foundry, construction, chemical industry, motor, machine tool and other industries.
