Application of Reactor Transfer Melt Pump in Plastics and Chemical Industry

The main function of the melt pump is to pressurize the high temperature plastic melt from the extruder and feed the flow into the extruder head steadily after stabilization. Its ability of stabilizing melt pressure and flux is superior to that of various types of extruders. When it is used in series with a single screw or co-rotating twin screw extruder, the benefit of the whole production line is significantly increased. The main advantages of using melt pumps are:

1. Reduce the dimension tolerance of extruded products to the minimum, so that more products can be produced from materials per unit weight. When the dimension tolerance of extruded products is strict or the cost of raw materials is expensive, it is more necessary and valuable to use melt pump.

2. Combining co-rotating twin-screw extruder and melt pump into a mixing extrusion granulation production line, its mixing quality and output are greatly improved compared with the single twin-screw granulation unit. The energy consumption for processing per kilogram of materials can generally be reduced by about 25%.

3. Adding melt pump and extruder heads such as tubes, plates and membranes to the original single-screw or co-rotating twin-screw extruder can save the granulation process for direct extrusion products. This system is very suitable for extrusion products where materials need to be blended and modified. In addition to the advantages of Article 2 above, the melt pump system can save energy by simplifying the production process of extruded products and shortening the production cycle.
