Rappers are time-controlled systems provided for removing dust from the collecting plates and the discharge electrodes as well as for gas distribution devices (optional) and for hopper walls.
Rapping systems may be actuated by electrical or pneumatic power, or by mechanical means. Tumbling hammers.
We supply 2 types of Rappers
- Tumbling Hammer
- Electro Magnetic Top Rapper(110V /220 V)
TUMBLING HAMMER :
Typically used in conjunction with rigid frame discharge electrodes, are highly efficient , when employed in a moving gas stream. Hammers are connected to a rotating shaft. As they revolve, the hammers collide with a beam, causing a vibratory shock to dislodge caked-on dust. The hammer's weight and mounting arm length control the intensity of the rapping. Adjusting the speed of the rotating shaft alters the frequency of rapping.
Electro Magnetic Top Rapper :
It is an electromagnetic device with the plunger being the only moving part. The vertical configuration is supported from the precipitator roof, eliminating rebound related failures and maximizing acceleration response to the electrode system.
