The Robson Airglide Belt Conveyor is a development of the traditional belt conveyor, but instead of carrying idlers it employs a cushion of air, being the means of supporting the loaded belt between the feed and the discharge.

The design uses the latest sheet metal fabrication t h l ith t b t li ht i ht

technology with strong but lightweight construction. These sections are generally pre-assembled and delivered to site as head, tail, 3m intermediate, and make-up, casings, all designed to bolt together to form the requisite length of conveyor.

Each casing section is sealed with self-adhesive sealing tape between the joints to ensure continuity of the air plenum without leaks. The loaded Airglide belt is supported on a cushion of air supplied by the longitudinal air plenum.

Air is injected at regular intervals along the "U" shaped bedplate to the underside of the belt, generating a low friction support cushion. A small blower unit supplies the low-pressure filtered air to the plenum, which in most instances is sufficient to s ppl the total belt lengthto supply the total belt length.

The unique Airglide Conveyor weatherproof design ensures the product is safe from weather degradation and suitable for Open or Tubular Gantries. With lengths in excess of 100 metres.

Airglides are available ATEX rated for use in explosive atmospheres and flammable dusts.

Robson have a specialized dedicated team in the design and construction of Screw Conveyors.

Each Conveyor is bespoke to the customer's requirements,with infinite choices for the Size, Speed, Material or Application.

Screw conveyors have a variety of uses. Variations in the flight design allow Screws to:

•Convey

•Mix

•Feed

•Elevate

Materials such as Sugar, Cement, Biomass, Effluent, Sludge Cake, Food stuffs, Animal Feed, Ash, Refuge, Glass Cullet, Granules, Limestone, Meals, Salt, Sand, Wheat and Barley.

With the bespoke construction of the screw conveyor it is possible to have multiple in feeds and a single out feed

Made for heavy duty the Robson Screw Conveyor is robust and reliable.

Robson have the capability to fabricate not only the screw conveyor but Silos, Bunkers, Staging, Structural Steel Work and all forms of Conveyor Equipment
