double piston hydraulic screen changer with double working positions
Features include
1, It matches with extruders of different design. it is applicable to process 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, thus eliminate the defects on final products
4,superior sealing system completely eliminates polymer leakage.
5, external safety cover gives better appearance and safe protection.
How to work
The double piston Screen Changer allows for filtration of most all polymers without interrupting production during a screen change. The Screen Changer consists of two pistons with each containing a filter cavity. When a screen change is required, one of the pistons is moved out of the housing while the other remains in the operating position. The dirty screen pack is removed and replaced with a new one. The piston is then moved back into the housing to its venting stages before resuming operation. These steps are then repeated for the other piston. This concept allows for continuous filtration with no interruption or loss of production
