Capacity is defined as the weight or volume per hour of a bulk material that can be safely and feasibly conveyed using a screw conveyor. Screw conveyor diameter is determined by multiple factors including capacity. The following steps are required for proper screw conveyor selection Calculate required capacity in cubic feet per hour (ft 3 /hr).

Basic Theory and Design Screw conveyors are volumetric conveying devices. With each revolution of the screw a fixed volume of material is discharged. The purpose of a screw conveyor is to transfer product from one point to the next. Screw conveyors are always control fed at the inlet by another conveyor
