The small wire mesh continuous-through shot blasting machine belongs to continuous passing processing equipment. Conventional shot blasting equipment cannot clean workpieces with complex irregular shapes, yet the mesh belt through-type shot blaster perfectly makes up for this shortcoming. It adopts a wire mesh conveyor belt to automatically and continuously feed workpieces into the shot blasting cleaning chamber. The machine removes scale, oxide layers and other surface contaminants, restores the original metallic luster of workpieces, increases surface roughness, and greatly improves the corrosion resistance of finished parts.
Cleaning and strengthening carried out by the mesh belt through-type shot blasting machine is a cold treatment process. The motor drives the blasting wheel, and countless tiny spherical steel shot continuously impact the workpiece surface. Each steel shot strikes the metal part like a tiny hammer hitting the surface, creating tiny indentations. The formation of each indentation stretches the metal surface. Beneath the surface layer, compressed metal grains attempt to rebound to their original shape, generating hemispherical compressive stress under powerful compression. Countless overlapping indentations form a uniform residual compressive stress layer, which further boosts the apparent hardness and fatigue resistance of workpieces and greatly extends their service life.
