Jet filters are used as receiver bin and cyclonic separator for the separation of material & air in pneumatic conveying systems.
The material-air mixture enters the filter receiver at the bottom part of the cylindrical housing or the discharge cone. The jet filter acts as cyclonic separator, solids are partially pre-separated by means of gravitation. The actual separation of the material-air mixture into clean air and material happens in the silo hoses (or cartridges).
Nozzles pressurize the filter hoses individually with air pulses and clean them from the inside, forcing any powder resiude back into the cyclone. This requires oil-free, dry air pressurized with 6 – 8 bars. The controls system activates the nozzles in a periodical sequence.
