ABSTRACT:
In the operation of a melter/mixer-gear pump system for processing of synthetic thermoplastic materials, the improvement is disclosed which comprises employing the pressure between the melter/mixer and the gear pump as the controlling parameter which affects, in a proportional relationship, the speed of the gear pump, the energy transmitted to and the consequent temperature of the materials passing through said melter/mixer.
