How the pneumatic hammer works

In a state where the pneumatic hammer is not supplied with compressed air (3 Kg/cm or more), the magnetic piston is fixed to the substrate by a strong magnetic force. When the three-way solenoid valve is energized, the compressed air flows into the pneumatic hammer body, and the pressure in the body increases. When the magnetic force is greater than the magnetic force, the magnetic piston is separated from the substrate at a high speed, and a strong counter force is generated due to the reaction force of the strong magnetic force. The high-speed falling magnetic piston hits the substrate, and its impact force is transmitted to the silo, and the attached dust is shot down with a strong impact force. When the three-way solenoid valve stops energizing, the compressed air in the body of the pneumatic hammer is discharged through the three-way solenoid valve, so that the magnetic piston is slowly raised by the return spring and then close to the substrate, and is returned to the initial state by magnetic adhesion on the substrate.

There is a strong magnetic magnet inside the hammer head. Before the action, the magnetic hammer head is tightly attached to the magnetic substrate. When the three-way solenoid valve is energized and the intake pressure is greater than the bonding magnetic force, the magnetic hammer head is separated from the substrate at a high speed and impacts to the bottom. After the impact, the three-way solenoid valve is de-energized, the gas inside the product is removed, and the hammer is reset. The impact of the air hammer is transmitted to the pipe or the silo wall to allow the material to flow smoothly.
