    2021-4-20 · Horizontal screw conveyors are the most widely used type of screw conveyor. Used to convey bulk materials from one part of a process to another horizontal screw conveyors are available in a wide range of sizes lengths configurations and materials of construction. Screw conveyors 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. Trough loadings of 15 and 30-percent are typically used for denser sluggish and more abrasive bulk materials. The inlet of a screw conveyor is always control fed by another device such as The recommended location for the drive unit is on the discharge end of a screw conveyor which pulls the bulk material to the drive end. with this arrangement each screw section is put in tension as the bulk material is conveyed toward the discharge of a screw conveyor
