When screen change
1), Cooling – water (8 –20 degrees C) is circulating in the entrance and exit blocks. This creates a pressure tight Polymer Plug or seal at both the screen Entry port – keeping the polymer in and air out and at the Exit port. At the Screen Exit the water-cooling maintains a sold Polymer Plug (seal) that contains the filter screen.
2). Heating – When a screen change is needed the two cartridge heaters at the exit, heats the tip of the Polymer Plug permitting it to move. Four high quality cartridge heaters maintain temperature levels in the main section of the auto continuous screen changer
3). Screen Advances - The Polymer Plug (containing the screen and impurities) that is under pressure moves out of the exit for a predetermined length determined by the timer or pressure regulator or manual operation. This also moves the contaminated screen across the flow of plastic and a fresh screen section enters.
