SPIRALFEEDER Flexible Screw Conveyors for Bulk Handling
SPIRALFEEDER flexible screw conveyors are enclosed tubular conveyors designed for conveying powders, granules, blends, crystals, flakes, and a wide range of other bulk materials. Typical applications include the conveying of bulk solids into overhead surge hoppers or the conveying of materials from one processing point to another, efficiently, quietly, and dust-free.
These conveyors feature a variety of spiral types based on the properties of the material being transferred: round, flat or knife edge spiral types. Custom spirals can be requested if necessary.
The round spiral shape minimizes friction for transferring sensitive materials such as coffee beans with a gentle conveying action. The flat spiral shape acts as a rotating shelf to transfer large volumes of materials with low bulk densities, such as cake mixes and mica, at high flow rates. The knife-edge spiral shape is designed to transfer challenging materials that cake, pack, stick or smear without clogging the system or degrading the material.
All spiral types feature carbon steel or optional stainless steel construction for sanitary processing and can be specified in a wide range of lengths to fit the installation.
