After selecting the peening switch the shots will be fed automatically by sound-abrator valves for both the wheels operated by solenoid valve and pneumatic cylinders, opening the mechanism. Shots are propelled on the rotating coil springs at high velocity thereby peening it. Dust generated during peening is sucked with media or shots in a media trap where shots are separated from the fine dust.
The dust further passes in the dust collector and gets trapped in filter bags. Clean air is let out in the atmosphere there by keeping the environment eco friendly.
