Discuss why melt pumps are rarely used with twin-screw extruders

What will be an ideal response?


The purpose of the melt pump is to insure that a specific and dependable amount of material is moved through the equipment downstream of the melt pump. It is a positive displacement pump. The action of a twin screw extruder is also that of a positive displacement pump, although not as positive as a melt pump.
Nevertheless, the action of both is similar and, therefore, not needed together.
