Uth promotes gear extruders

Uth is promoting its Roll-ex gear extruders, highlighting that they are specially beneficial for sensitive process steps. According to the company, the use of a gear extruder lends itself to economical fine mesh straining of rubber compounds in a manner that is also gentle on the materials and also to the precision extrusion of tyre components.

Furthermore Uth reports that the modularly structured roll-ex system makes fine mesh straining possible in a variety of ways, especially in mixing lines. Thus, the TRF feeder with two-roll feeding assembly, for example, can be integrated easily in existing plants thanks to the short overall length. Depending on the application, other feeding systems such as conical double-screw extruders or screw extruders can be integrated modularly. 

Precise extrusion is another core feature of roll-ex gear extruders, which distinguish themselves by the sophisticated engineering and applicable working pressures of up to 800 bar. Particularly for the demand of the tyre industry a Two-Roll Plastisizing unit has been developed. If needed a strainer unit can be integrated.
