Working Principle

A spiral screw (or two, three screws according to specified application) inside of the DP PerMix PNA series Conical Screw Mixer rotates by its own axle parallel and near the wall of the cone vessel. It lifts the powders around it from bottom to the top, and then the powder falls down due to the gravity. At the same time, the spiral screw rotates around the center of the cone like a planetary, so that the powders in every corner of the cone can be mixed by the screw.
