Screw Conveyor - CA Series

Presentation

Screw conveyors are one of the most widely used systems for moving bulk materials in general, along horizontal or moderately inclined paths up to 17°.

Their intrinsic simplicity has led to them being adopted for the most diverse industrial applications throughout the world. Metalmont screw conveyors are suitable for conveying granular materials, particularly 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 CA Series conveyors (CA series open auger horizontal conveyor) 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.

Accessories

Metalmont CA Series conveyors are available with a series of accessories that facilitate their effective installation in the plant.

Loading and discharge: for loading and discharge of material, various hoppers are available for connection to the tail (loading) or head (discharge). The connections can be round in different diameters, with or without flanges or with square flange.

Universal joint: to carry material along a slightly inclined flight, the spiral can be made in two sections that are connected to each other by means of a universal joint (suitably supported by specific intermediate members).

Cradles and stoppers: cradles are floor-standing, height- adjustable mounts for the different sizes of screw. Stoppers are used on silos, to seal the profile of the screw on the wall.

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.
