Steel grit of application:
Cleaning: peen-forming cleaning, body.they, die casting cleaning, casting peen-forming cleaning, forgings peen-forming cleaning, forgings body.they castings rust-removing steel cleaning, steel plate cleaning, cleaning, h-beam cleaning, steel structure cleaning. Derusting: peen-forming derusting, shot peening derusting, casting, forging, steel derusting rust rust, forgings except oxide skin, steel derusting, h-beam derusting, steel structure rust.
Conslidation: shot peening strengthening, heat-treated pieces shot peening, gear shot peening.
Shot peening: steel shot peening, sections of sandblasting, presented.the peen-forming, steel plates, steel shot peening shot peening.
Peen-forming: plate peen-forming, steel shot bla, sections peen-forming.
Play sand: play sand treatment.
Steel shot pretreatment: before painting processing, coating pretreatment, surface pretreatment, presented.the pretreatment, steel pretreatment, steel pretreatment, steel pretreatment, steel structure pretreatment.


Various hardness steel grit:
GP steel grit: new made, be pointed leng shape, in use process edges was soon ground round, especially suitable for the descaling and surface preparationg applications.
GL steel grit: although this type of hardness of the steel grit than GP steel grit, some high during shotblasting also loses its sharp edges, particularly suited to descaling and surface preparationg applications.
GH steel grit: such a high rigidity, in steel grit sandblasting assignments will always maintain edges and corners, to the formation of these rules, the surface of the wool is especially effective. GH steel grit shot peening machine for homework, should consider the construction requirements prior to price factor occasions (e.g. abrasion rolling processing). This steel grits are mainly used for compressed air shot peening equipment.
