Title:
CONTROL SYSTEM AND METHOD FOR CONTINUOUS KNEADING MIXER HAVING MOVING TYPE SURFACE DISCHARGE APPARATUS
Document Type and Number:
Japanese Patent JPS62125832
Kind Code:
A
Abstract:
Disclosed is an apparatus and method for controlling a continuous mixer 10 having a discharge formed as a gear pump 30 or an extruder screw. The continuous mixer 10, which includes a charging orifice 20 spaced apart from a discharge orifice 16, feeds material fed through the charging orifice 20 through at least one chamber 14 by one or more bladed otors 18 which are controlled by a motor 26. The discharge of this material through the mixer 10 is controlled by the gear pump 30, and the RPM of the pump gears 36 is controlled in relation to the torque produced by the motor 26 which drives the bladed rotors 18. A change in torque produced by this motor 26 will result in a change in the RPM of the pump gears 36, thereby maintaining the rotor torque and consequently the mixing energy exerted on the material being mixed in the mixer 10.
