Performace of this kind of two chanel screen filter for polymer melt filtration
1, It can match with extruders of different design. It is applicable to process with most polymers at high output.
2, Double-channel nonstop screen changer work alternatively, which can change the screen with minimum melt pressure fluctuating and production interrupting.
3, Two stages air vent for the hydraulic system to eliminate bubbling in polymer flow.
4, Superior sealing system completely eliminates polymer leakage.
5, External safety cover gives better appearance and safe protection.
6, It is equipped with circular\elongated or U- shaped screens, for enlarged filtration area.
screen chaning process of this two chanel screen filter for polymer melt filtration
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
