Non-stop double-plate hydraulic screen changer series: ● the use of advanced pressure seal technology, through the polymer in the net driving pressure sealing element to achieve the optimum sealing effect, and for network more quickly. ● high quality alloy steel after nitrogen treatment, significantly extend the product life cycle. ● alternating mode, to ensure that the process for network streams continuous, stable and reproducible process parameters. ● After rheological optimized honeycomb panels, effectively reducing the extrusion process fluid shear. ● The internal heating device, safety and energy conservation. Closed traces, nice. ● Modular combined mode, suitable for different standard extruder, and easy to clean.
