PURPOSE:To prevent sepn. of a mixture by providing a proportional mixer having a low machine height, enabling the direct connection of said mixer to the apparatus, etc. in the succeeding stage, eliminating the need for any transporting machine in between and reducing the distance between said mixer and the succeeding stage. CONSTITUTION:Plural chambers 21 penetrating in a vertical direction are delineated around an approximately perpendicular spindle 18, and dampers 22 are provided in the lower part of the respective chambers 21 to close the lower parts of the chambers 21. A feed port 24 communicating with the upper part of a part among the chambers 21 is provided fixedly right above the chamber 21 and two driving systems 27, 28 rotating at different speeds are made selectively connectable to the spindle 18. An open-shut consisting of a lever 31, a spring 32, a rotor 33, a cylinder 34, a lever 35, a cam 36, etc. is provided engageably and disengageably to the from the damper 22 side and is engaged in the prescribed position with the damper 22 side in a part of the chambers 21 rotating together with the spindle 18 to open the damper 22. |
