Abstract
Disclosed is a system and method for controlling a continuous mixer having a gear pump discharge or an extruder screw discharge. The continuous mixer, which includes a charging orifice spaced apart from a discharge orifice, feeds material fed through the charging orifice through a melter/mixer. The material is caused to move through a chamber by one or more bladed rotors which are controlled by a motor. The discharge of this material through the mixer is controlled by the gear pump, and the RPM of the pump gears is controlled in relation to the torque produced by the motor which drives the bladed rotors. A change in torque produced by this motor will result in a change in the RPM of the pump gears, thereby maintaining the rotor torque and consequently the mixing energy exerted on the material being mixed in the mixer.
