2) Single plate hydraulic screen changer with four separate filter blocks:

Product introduction and applications:
◆ It consists of filter body and four separate filter blocks. Filter blocks work by turns.
◆ Small fluctuation of pressure in process can keep production continuous and stable.
◆ With filter plate preheat and exhaust, it can keep pressure, flow and temperature stable. It is especially for high transparency and precision products.
◆ It can change filter plate with no leakage, no damage film, no break thread, no stop.
◆ Filter plates move in one-way, work independently, easy to clean.
◆ It can be used for granulation, pipe, plate, sheet, EPE, EPS pearl wool, xps extruded sheet, PVB bursting disk, space plate, squeeze net, BOPET/BOPP, chemical fibers. In PE, PP, drawbench, PEP, EPS production lines, the effect is stable and remarkable. Improved products can meet drawbench of PET and other polyester products.

Principle of operation:
The below of drawing shows the basic function and specification of the single plate type four working station hydraulic screen changer. The four pieces of square shape filter plate are placed between inlet and outlet. The hydraulic station will supply the necessary power to push each screen move to the working station with proper movement. The stainless filter holes will smoothly move into the flow channel without causing much fluctuation and meantime realize self-cleaning function.

◆ This screen changers for extruder realize non stop screen changing operation by two pillar with double filtering areas.
◆ Designed lead material exhaust structure, during changing screen with material flow no stop, and then realize no stop changing screen.
◆ Suitable for most polymer extruded production.
◆ During changing screen with no stop production, it cannot cause fluctuation to extruders.
◆ It can work well in 25-30Mpa pressure condition.
◆ It is used for chemical, blown film, flat film, cast film, pipe, plate, wire, fiber, cutting line, recycling and so on.

◆ Simple operation, simple screen changing, and continuous working.
◆ Easy maintenance, leak-free processing, endures precise processing, high product quality and reduced waste materials.
