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).
