The small wire mesh through-type shot blasting machine belongs to continuous pass-through processing equipment. Conventional shot blasting equipment fails to thoroughly clean irregularly shaped workpieces, while the wire mesh through shot blaster perfectly remedies this drawback. It adopts a wire mesh conveyor belt to automatically and continuously convey workpieces into the shot blasting cleaning chamber. The machine removes mill scale, oxide layers and other contaminants on workpiece surfaces, restores the natural metallic luster of parts, increases surface roughness, and greatly improves the corrosion resistance of finished workpieces.
The cleaning and strengthening process conducted by the wire mesh through-type shot blasting machine is a cold working treatment. The motor drives the blasting wheel, and countless tiny spherical steel shot continuously impact the workpiece surface. Each steel shot strikes the metal component like a tiny hammer, forming tiny pits and 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 strong compression force. Countless overlapping indentations create an even residual compressive stress layer, which further elevates the apparent hardness and fatigue resistance of workpieces and greatly extends their service life.
