AFC offers round, flat, knife edge spirals for peak efficiency.
SPIRALFEEDER flexible screw conveyors from process equipment manufacturer Automated Flexible Conveyor feature a choice of spiral types to ensure the screw design promotes highly efficient material transfer when conveying nearly any type of powder, pellet, flake, or other bulk material. Specified based on the properties of the material to be transferred, the AFC screw conveyors are offered with either round, flat, or the company's proprietary knife edge spiral types as standard, along with custom spirals if necessary.
The round spiral shape minimizes friction for transferring sensitive materials such as coffee beans with a gentle conveying action on a durable platform for long life and low maintenance. The flat spiral shape acts as a rotating shelf to transfer large volumes of materials with low bulk densities at high flow rates such as cake mixes and mica. 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.
