How are powders and bulk solids discharged from the Circle Feeder (Mass Flow Feeder)?
A simple experiment will explain the principle. Place a cylindrical container with an open bottom on a flat surface. Fill the cylinder with a powder. Next, lift the container a few millimeters from the flat surface. A small amount of powder will flow from the cylinder between the edge of the cylinder and the flat surface. A larger gap between the cylinder and the flat surface will allow for more powder flow. Next, insert a wire on the flat surface lengthwise across the cylinder opening. As the wire is rotated, powder is moved to the periphery and the cylinder can be completely emptied. This is the concept behind the Circle Feeder.
