Crawler shot blasting machine for surface cleaning of various parts. Where the sticky surface of sand casting metal cleaning, surface rust black metal parts, stamping burrs and edges of the back surface of a blunt, forging and heat treatment, surface treatment of the workpiece and the spring surface oxide removal and surface of the grain refinement Dengjun This series of devices can be enhanced technology to achieve shot. The broad range of applications, mainly foundries, heat treatment plant, electrical plant, machine tool factory, bicycle parts factory, power machinery, auto parts factory, motorcycle parts factory, non-ferrous metal die-casting factory. By shot blasting treatment, the workpiece material available to a very good character, but also the surface of metal parts could be black, blue and passivation process before the procedure, while at the same electroplating, paint and other finishes to provide a good base surface . After blasting through the machine can reduce the tensile stress in the workpiece, while the surface grain refinement, so that the surface hardening, to increase their service life. 

 The shot blasting machine and low noise, low dust, high efficiency, while the projectile can automatically recycle, reduce material consumption and reduce costs, modern enterprise is the ideal surface treatment equipment. 
 The shot blasting machine models QPL30, QPL60, QPL100, QPL300 and so on.
