Features included
1,In the normal working time, The two filter screen of this two chanel screen exchange filter for PP sheet extrusion line work in the same time . And when screen changer is required, one screen is pushed out, and the other one is still on the working position, thus without interrupting the flow of material and production. also , this screen exchange process without stopping the going-on extrusion machine.
2, This type of two chanel screen exchange filter for PP sheet extrusion line equipped with air vent system, which can fully defuse the gas mixed in the materials when change the screen , then improving product quality.
3, this two chanel screen changer we have several type to meet different product capacity.
to increase the filter screen area, we have the oval screen , and square screen is wrapped on the slide bar.
4, for some customers large capacity extrusion line, we have the large screen area type of two chanel screen changer, or we can design tailored products for them ,for example, two sets of screen changer installed side by side. I will show you as follows.
How to work of this two chanel screen exchange filter for PP sheet extrusion line
To change the screen, the pistons are ejected from the housing one after the other using hydraulic cylinders. Once replaced, they are returned to their production position in the same way. During the brief screen change process, the melt flows continuously through the other piston, thereby ensuring the system's constant operation
