(under subclass 58) Apparatus including a rotary member such as a plate, disc or cup which throws the material against a receiver such as a conical hopper.
(1) Note. In many of these apparatuses the material is thrown into a receiver from which it falls to another thrower and so on in succession. For other similar apparatus not using centrifugal force, see this class, subclass 165 and appropriate indented subclasses.
