Rotary Clearner - PR Series

Presentation

The rotary cleaner is a grain pre-cleaning system consisting of a central body containing a rotating drum formed by an inclined drive shaft, connected to spoked wheels that act as a support for the various perforated sheets.
 
Product is fed into the machine through an in-feed pipe connected to a spout that carries it into the rotating drum. The material is kept in the centre of the drum by two shakers and passes through the various sheets, before exiting through a discharge hopper. At the end of the machine is another hopper which is used to collect waste deriving from the cleaning cycle.

Metalmont PR Series cleaners are suitable for cleaning 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 PR Series cleaners 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 PR Series cleaners are available with a series of accessories that facilitate their effective installation in the plant.

Mezzanine platforms: at the customer’s request, Metalmont can build intermediate floors for ideal positioning of the cleaner inside the plant, accompanied if necessary by other machines such as PA series aspirator cleaners.

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.
