INTERNAL MIXER

摘要

A method and apparatus for controlling the discharge of an elastomeric material from a high intensity mixing machine having a mixing chamber with two rotors and an outlet with a drop door. The drop door is open when the rotors are in a predetermined preferred position for unloading the mixing machine in response to the positions of indicators on the rotor shafts. Sensors mounted in the wall of the outlet determine when the gate is clear after unloading of the mixed elastomeric material whereby the drop door may be moved into the outlet for closing of the mixing chamber as soon as the unloading is completed.
