Abstract
A high-efficiency, tandem biaxial dynamic sorting and return powder milling device with automatic baffle regulation, which is used for the sorting of a gas-solid two-phase fluid of an air-powder mixture, is provided. A circle of milling gears for staged milling of return powders is mounted in an annular cavity between an outer conical housing and an inlet pipe; an axial flow airfoil-type vane is fitted on an outer side of a lower part of an inner conical body which is, as a whole, driven into rotation by a variable frequency motor; a movable vane rotor for centrifugal sorting is fixedly fitted on an outer side of a top cone; and the degrees of opening of first-stage baffles and second-stage baffles are respectively controlled and regulated by an automatic baffle regulating mechanism.
