Advantages of using an extruder and a melt pump in an extrusion granulation production line

The melt pump has the advantages of high precision, no pulsation, and long service life; the extruder system is equipped with a melt pump, which can effectively reduce the tolerance of the extruded product and improve the quality of the final product. For products with strict dimensional tolerance requirements, the use of a melt pump will effectively improve the economic benefits of the enterprise.

In a mixed extrusion granulation production line combining a twin-screw extruder and a melt pump, the use of a melt pump can effectively reduce the self-pressure building function of the twin-screw extruder and improve its production efficiency (the self-pressure building function of the twin-screw extruder is poor, which seriously affects the production efficiency). For a production line composed of a twin-screw machine, a melt pump, an extruder head such as a pipe, a plate, and a film, it not only has the advantage of building pressure, but also can simplify the production process of extruded products, shorten the production cycle, and achieve energy saving. The twin-screw machine and melt pump configuration are particularly suitable for the extrusion of materials that require blending and modification; the materials must be mixed and homogenized as allowed to meet the quality requirements of the product. In this production process, it is generally carried out in two steps; one step is to mix the raw materials into pellets, and then use another device to reheat and melt the pellets, and then extrude them into finished products. In these two steps, the molten material is first cooled to room temperature, and then heated to a molten state for extrusion, which is accompanied by considerable energy consumption. For extrusion equipment using a melt pump, this considerable energy consumption in the traditional extrusion process can be saved, thereby achieving the purpose of high efficiency and energy saving.
