Pneumatic hammer

When no compressed air (standard air pressure: 3–7 kg/cm²) is supplied to the pneumatic impact hammer, the magnetic piston is firmly attracted to the base plate by strong magnetic force. After the solenoid valve is energized, compressed air flows into the hammer body and raises internal pressure. Once the pressure exceeds magnetic attraction, the magnetic piston separates rapidly from the base plate and generates powerful impact force from magnetic reaction. The high-speed piston strikes the base plate, transferring impact energy to the silo and removing adhered dust. When the solenoid valve is de-energized, compressed air inside the hammer exhausts. The return spring pushes the magnetic piston upward slowly until it reattaches tightly to the base plate via magnetic force and returns to standby status. The periodic impact force effectively solves problems such as material adhesion, hanging residue, blockage and bridging of powder materials.
