Melt pump and screen changer

As a manufacturer engaged in the production of plastic industry, how to choose a suitable for their own production line of net changer? If you are just entering the line, it is estimated that everyone is echoing the cloud. If you want to choose a suitable network changer, as a user you should clearly know your needs, please grasp the following points:

First, consider the characteristics of their own raw materials, because each raw material melting point, melting fingers, corrosion, liquidity is different, the requirements of the net changer is naturally different.

Second, considering that the raw materials they use are new materials or old materials, if it is old materials, how much is the impurity ratio of old materials? What size filter area is recommended by the equipment manufacturer?

Third, consider their own production of products, different products for the continuity of production requirements are different, the requirements of rod granulation can not be broken, do casting film requires small fluctuations in the pressure of the net, etc., which should be determined according to the actual situation of their own production.

Fourth, consider whether the extruder you use is single screw or twin screw and the model of the extruder, usually the diameter of the filter screen is not less than the diameter of the screw.

Five, considering the output of the extruder is how many kilograms/hour, we can not match large, so waste money; With a small, small horse cart, not only reduce the life of the host, but also increase the frequency of network change, to stop.

Six, know the maximum pressure of the material flow is how much Mpa, if you ignore this point, the configuration of the net changer is prone to leakage or push and pull the phenomenon.

For users, suitable is the best, neither the pursuit of high appearance level, full function, but also do not blindly pursue money saving. Configuration of the net changer is not an article can express clearly, just like you can not learn to give medical treatment through an article is a truth, the need to seek truth from facts, specific problem specific analysis, the accumulation of professional knowledge and practical experience precipitation.
