Operating principle of the shot-blasting machine for roll texturing

The operating principle of a roll-texturing shot-blasting machine involves converting the kinetic energy of the shot into impact force against the workpiece surface through a powerful, high-speed stream of media directed at the roll. This process work-hardens the roll surface, resulting in a denser hardened layer. Crucially, it does not damage the metal grain structure at the surface, thereby enhancing the roll's surface fatigue strength. The effectiveness of the shot-blasting process depends on the quantity, size, velocity, and impact direction of the shot media. This treatment improves roll performance and service life while preserving the integrity and strength of the roll surface.
