Air Blaster


Pneumatic Control Panel

  S.S. Casting Nozzles & Fabrication  




The basic principle of Baani Air Blasters operation envisages introduction of Compressed air at a velocity with kinetically activates dust particles clinging to any surface, with this enrgery making them vibrate and break free from other particles and surface to with they had adhered.

The compressed air is stored in an air receiver which maintains the air pressure at 6 to 7 kgf/sq. cm. This compressed air is fed to the point of discharge through a 100 mm.




Opening through operation of pneumatically controlled valves. The sudden but controlled release of compressed air into the stored material is at a rate faster than the material can absorb it, thereby causing the material to get dislodged and move. The controlled release of air ensures that the reaction is not transmitted to the support structure and also there is minimal effect of noise or vibration. The actuation of the blaster can be effected either manually or through Electronic Sequence Timer.




One Cycle of filling and release is described as follows : Fillings : Compressed air is supplied through air pipeline controlled by a solenoid valve to quick exhaust valve. The diaphragm of quick exhaust valve closes the 3/4 inch outlet. The compressed air flows past the diaphragm into the piston chamber. The compressed air flows past through an opening in the piston into the receiver and fill it with air untill the pressure in it equals that in the pipeline. The pressure in the receiver is maintained and the unit is now READY OR FIRING.

Release : By actuating the solenoid valve, bothe and control air in pipeline and the compressed air stored up behind the piston are released by simultaneous actuation of the quick exhaust valve. The compressed air stored inside the receiver makes the piston to lift off its seat and after moving equal to only a quarter of the outlet pipe diameter release the whole discharge cross section without restriction loss. The air is blown very rapidly within milliseconds into the Bunker, Hopper, Silo, Chutes etc. So that an almost explosive effect is obtained. After this, the spring forces the piston back to its initial position so that the outlet is closed again and no material can get into the interior of the vessel.
Firing sequence is from bottom to top in case of Hopper, Bunkers, Chutes and Cyclones and the sequence is from top to bottom in case of cement pre-heater tower.


The Advantages :
The Baani Air Blasters offer several advantages coupled with diversity of their use or various industries which assume importance in view of greater necessity of uninterrupted plant operation.
