Harden produce standard models of hydraulic screen changer in mass, we specially produce for manufacturer of extruding plant. Short-term delivery, firm durable, integrated organism, quickly screen change without line stopping, using electric heating, standard connection port, wide range of applications. There is less effect on extrusion work when using hydraulic screen changer to screen change. It can be applied to most plastic or rubber extrusion work. Normally rapidity of changing from 1 to 1.5 seconds per times, depending on the size of the filter.

The distance between Screw and breaker plate can stay10 mm recently, thereby reducing the possibility of polymer degradation. The screw can pulled out through the screen changer after removed the breaker plate, suitable for single extrusion and co-extrusion production line. All-metal sealing system easy to adjust that ensure screen changer sealing and run without leaking. Applied to melt temperature up to 300 º C and melt pressure up to 40MPa. option of horizontal or vertical installation.

Specific of hydraulic screen changer

• Seal structure, pressure activation.
• Easily maintain, durable sealing ring.
• Working temperture achieve 300^oC.
• Melt pressure achieve 40MPa without leaking.
• Standard flange connect.
• Can work with shield, to prevent crush and scald.
• Low capital and operating costs.
