Feeding Basics
The elements of a good feeding system are: 1. Adequate on demand supply of material of a relatively uniform density to the feeder; 2. The complete filling of a volume (screw flight) with a uniformly dense material; 3. Striking off the excess material from the screw flight as material enters the feed tube; 4.
