The Screw Conveyors are a mechanism that uses a rotating helical screw blade, called a flighting, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. They are typically designed to convey bulk materials at 15, 30 or 45-percent trough loading, depending upon material characteristics of the specific bulk material. As a general rule, trough loading of 45-percent can be used for light, free-flowing and non-abrasive bulk materials. The offered Screw Conveyors are also more economical alternatives to a belt, pneumatic, or aeromechanical conveying device.They are very efficient and easy to install.
