New generation continuous screen changer for plastic extruder

This new generation continuous screen changer is our patent owned product. it developes based on the screen changer with four screen recycled , in the past time, the screen changer with four screen was very popular, but it's not very easy to operation,   and our engineer invented this new generation continuous screen changer. with higher performance and easier operation.

This kind of new generation continuous screen changer DHBL series consists of the screen changer body, the hydraulic unit and electrical controlling pack.

This kind of screen changer now is widely used for the XPS/EPS/EPE foaming products extrusion machine.
And  also used for the plastic recycling granulator. and our customer feedback that the effect is very good.

The advantages of this new generation continuous screen changer

1, no need to stop the working machine when change the screen
2, no interrupted the production when change the screen.
3, air vent system improve the quality of the products, no any bubble in the product, and make the surface of the products smoothness.
4, easy to operation, less labor interference.

Technical Data:

The new continuous screen changer is especially applicable to foaming plate products such as XPS, EPS, EPE and cast film. It ensures the screen changing without machine halt or production interrupt, which has been widely tested and verified in production practice.

Do you want to know how does this kind of new generation continuous screen changer work?
The following schematic diagram shows the screen changing process

Performance characteristics:

1,No need to stop the working machine when changing the screen, no material explosion, noiseless, no material leakage, or production interrupt while working.

2,This screen changer (self-owned patent ) is characterized by the convenience and safety to change the filtering screen with it. It is time-saving to install the filtering screen with the screen changer, and there is no need to manually disassemble the machine, adjust the para-position screen, or install the lock pact between different screens, thus the screen changing operation will be reduced by 90%.

How long does one set of screen changer could  be used?

This kind of screen changer adopt the high quality of the alloy steel, high pressure resistant , high wear resistant, high temperature resistant. generally said , one set of this kind of screen changer could be used for 5 or more years.
