Kellve - Screw Conveyors
Screw conveyors are usually used for transport of dry and wet materials, e.g. wood chips, smaller fractions of limestone, granulate, biomass and powder-like material. Our screw conveyors are usually included as units in a larger plant and we always adapt them according to your needs.
Screw conveyors have a simple and well-proven design, which makes them both reliable and durable. However, use of screw conveyors consumes more energy and needs more maintenance in comparison with belt conveyors, though their design can be an advantage in transporting, for example, materials that produce dust.
Screw conveyors are less sensitive than belt conveyors when it comes to gradient, it is generally possible to incline them more than a belt conveyor. From a capacity point of view, this way of moving material is not as effective as a belt.
