Cicloni per trasporto pneumatico | F.T.A. srl



Cyclone scrubbers are ideal for pre-filtration where there is great concentration of dust and the reduction of coarse particles. Versatile for all types of dust. Filter maintenance and replacement is favoured by access to the filter unit through large walkable covers aided by gas pistons in filters with top cartridge removal. Access is through a hinged maintenance door with seal for the maintenance and removal of cartridges in the lateral version. On request, the filters can be made with various types of sheet metal with the option of paint only the outside or inside-outside and anti-corrosion treatments.

  • High efficiency for coarse particles, reduction of fine particulate although with low efficiency;
  • Simplified maintenance given the lack of moving parts;
  • Simplicity of the dust recovery;
  • Need for limited space for the implementation of the system;
  • Low implementation and use costs;
  • Option of working at any temperature;
  • Option of working with damp fumes;
  • Good operational flexibility.
Operating principle

Cyclones are reduction systems which enable the separation of polluting particles without the use of moving parts exploiting appropriately shaped entrances. In detail, the gas and dust stream is passed into a system of two concentric cylinders. Gas entering is forced into a spiral movement from top to bottom in the cavity between the two cylinders. The gas can then leave passing through the internal cylinder, lower than the external one. The particles with higher inertia than the gas tend to strike the walls of the external cylinder and fall to the bottom of the system where there is a dust recovery hopper. The dust can then be recovered for the next stage of treatment. Ideally, a cyclone can be a cylindrical structure with a funnel-shaped exit, consisting of an inlet for the gas to be treated and an outlet. The ability to treat particles with more or less fine granulometry depends on the diameter of the cyclone.

Pneumatic transport

For trimmings of paper, cardboard, aluminium, plastic film, glass veils, etc. to be aspirated by
coiling and winding machines, cutters and retractors.

Transport takes place after the trimmings have been broken up with a centrifugal fan for scrapping. After the air-material separation, there is disposal on pallets, bale presses, pulpers etc. We supply the individual components up to turnkey installations.

The removal of the waste from the machines creating trimmings enables them to be used better and valorisation of the scrap. After the air-material separation with dynamic (cyclones) or static network separators, the trimmings can be compacted using an auger-press, bale press or recycled in the pulper.
