The hydraulic screen changer for extruder is an auxiliary machine for extrusion production line equipment, and the prices vary greatly. How to choose a hydraulic screen changer that suits your needs?

First, consider the characteristics of your own raw materials. Because each raw material has different melting points, melting points, corrosivity, and fluidity, the requirements for the screen changer are naturally different.

Second, considering whether the raw material used is new or old, if it is old, what is the impurity ratio of the old material? What is the recommended filter area for the equipment manufacturer?

Third, consider that the requirements for production continuity vary depending on the products being produced. For example, the requirements for drawing and granulation are that the production process cannot be interrupted, while for casting film production, the requirements are that the pressure fluctuation of the screen change is small.

These requirements should be determined based on the actual production situation. Fourth, consider whether the extruder used is a single screw or a twin screw, as well as the model of the extruder. Typically, the diameter of the filter screen should not be less than that of the screw.

Considering the output of the extruder is how many kilograms per hour, we cannot match it with a large one, which will waste funds; If the size is too small, it will not only reduce the life of the host, but also increase the frequency of screen replacement. It is necessary to stop at the right time.

know what the maximum pressure of the material flow is in Mpa. If this point is ignored, the configured hydraulic screen changer may easily experience leakage or difficulty in pushing and pulling.

In summary, when selecting a hydraulic screen changer, users should not blindly pursue cost savings or functionality. What is suitable is good.
