A sand blasting machine is the use of high-speed rotation of the impeller, the high-speed projectiles thrown workpiece surface, to clean up the surface of the device. Roller-through shot blasting machine using new efficient pulse jet bag filter, the dust filter wind speed (3-6m/min), small size, low resistance of the device, a small change in air volume, dust emissions far below 150mg / m3 standards. Roller-through shot blasting machine is mainly used in the manufacture of steel before (ie raw state) surface shot blasting. Shot using a large amount of high-speed projectiles direct-coupled centrifugal blast wheel. High cleaning efficiency, the quality of the surface cleaning up Sa2 ~ Sa2.5. Later by blasting steel processing, surface roughness must improve the adhesion of the film and the surface of the material, thus improving the corrosion resistance of the product. While also optimizing the production process of steel surface condition, reduce stress, increase the service life of metal parts.
