Screw feeders are devices suitable for handling a wide variety of materials that have good flowability characteristics. The screw feeder has a helicoidal surface fitted on a shaft that rotates inside a fixed tube. The material which comes out of the silo is pushed by the helicoid flight along the base of the tube in the direction of transport.
How to Design Efficient and Reliable Feeders for Bulk Solids
The key to proper screw feeder design is to provide an increase in capacity in the feed direction [4]. This is particularly important when the screw is used under a hopper with an elongated outlet. One common way to accomplish this is by using a design as shown in Fig. 1. Uniform discharge through the hopper outlet opening is accomplished through a
