SELF-CLEANING MIXING DEVICES AND METHODS OF USING THE SAME

摘要

The invention relates to mixing devices, methods of operating mixing devices, and methods of blending a granular substrate with a coating material. The invention provides for a method of operating a continuous mixing device comprising the steps of (a) operating rotational elements of the mixing device in a forward rotational direction for a duration of time; and (b) operating the rotational elements of the mixing device in a reverse rotational direction for a duration of time shorter than the time the rotational elements are operating in the forward direction, wherein said rotational elements are mixing solids, viscous liquids, or combinations thereof, and wherein the operation of rotational elements in the reverse direction is for a time sufficient to substantially prevent agglomeration of solids, viscous liquids, or combinations thereof on the rotational and/ or static elements.
