Why does melt pump increase product output in unit time?

In order to improve the extruder's output, after adding the batte PUMP melt pump, the pressure fluctuation of the extruder is in the rear of the pump, which can reduce the pressure inside the extruder, decrease the shear strength of the melt, slow the temperature curve and decrease the temperature rise. In particular, a few years after the operation of the old extruder, the internal screw between the screw and the barrel will produce a lot of wear and tear, leading to the gap is too large, the return of the melt will increase, the output will be reduced because of this effect. The use of batte PUMP melt pump will reduce the flow and energy consumption, which means that the volume of extruder in unit time can be greatly improved.
