Cyclone Separator


Cyclone separators are a very widely used system for reducing the amount of dust in the air from the aspirator cleaners. They are characterised by their intrinsic simplicity, which has promoted their diffusion.

Metalmont CI Series cyclones are suitable for cleaning cereals, seeds and their derivatives. In designing these products, Metalmont has scrupulously applied the latest and most stringent standards with regard to operator safety, reliability in the most arduous working conditions and construction quality, with the aim of reducing energy consumption and maintenance costs.

Metalmont CI Series cyclones are also available on request with ATEX 22 certification. The standard operating temperature range is 0 to 40 °C.

Information on our past installations and customer portfolio is available on request.


he range of Metalmont CI Series cyclones comprises 2 models, differentiated by their typical air flow rate. The main indicative properties are:

Model Air Flow Rate Material Load Capacity Discharge Diameter
  m3/h t/h mm
CI 060 4.500 60 260
CI 120 7.500 120 320


Metalmont CI Series cyclone separators do not have specifically dedicated accessories, but use other components produced by Metalmont (valves, fittings, pipes) that facilitate their effective installation in the plant.

The only recommended device is the star valve at the material discharge outlet, available in the Metalmont catalogue, for use in combination with specific fittings where applicable.

This valve uses a 0.75kW Motovario gearmotor with IP 55 protection rating.

Metal joinery components: in addition to specific accessories for the correct installation of its machines, Metalmont is also a long-standing supplier of more general but equally useful plant access and structural solutions such as staircases, rest platforms, inspection platforms, walkways, frameworks and bracketing of all kinds, from simple brackets to backstays for supporting long sections of piping, shelves and stands.
