When to Choose a Belt Conveyor Over a Screw
When a screw conveyor is used as a metering device, it is considered a screw feeder. Screw feeders are used to initiate a material process by metering product from a bin or hopper. Screw conveyors are very compact and adaptable to congested locations. Screw conveyors do not have a return similar to a belt or drag conveyor. Screw conveyors are totally enclosed to contain the product and prevent spillage.
