Hydraulic screen changer is an auxiliary machine for extrusion production line equipment, and its price varies greatly. How to choose a hydraulic screen changer that suits your own needs?
1、 Consider the characteristics of your own raw materials
Because the melting point, melting point, corrosiveness, and flowability of each raw material are different, the requirements for the screen changer are naturally different.
2、 Considering whether the raw materials used are new or old
If it is old material, what is the impurity ratio of the old material? What is the recommended filter area for equipment manufacturers?
3、 Consider the products you produce yourself
The continuity requirements for production vary depending on the product. The requirement for stretching and granulation is that the strip cannot be broken, and the requirement for changing the screen and reducing pressure fluctuations when making a cast film depends on the actual production situation.
4、 Consider using your own extruder
Is the extruder a 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.
5、 What is the output of the extruder in kilograms per hour
We cannot allocate large amounts, as it would be a waste of funds; Being too small not only reduces the lifespan of the main engine, but also increases the frequency of network replacement. It is important to be moderate.
6、 What is the maximum pressure of the material flow in Mpa
If this point is ignored, the configured hydraulic screen changer is prone to material leakage or inability to move.
In summary, for users, the selection of hydraulic screen changers should not blindly pursue cost saving or functionality. What is suitable is good.
