Roll-ex gear extruders from Uth GmbH are specially designed for economical fine mesh straining of rubber compounds in a manner that is gentle on the materials, as also to the precision extrusion of tire components.
The modularly structured roll-ex system makes fine mesh straining possible in many ways, especially in mixing lines, says Uth. 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. This machine technology also stands out thanks to the ease of cleaning and comfortable operation. Throughputs of up to 15,000kg/h are possible.
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 tire industry, a Two-Roll Plastisizing unit has been developed. If needed, a strainer unit can be integrated. The roll-ex gear extruder system will be exhibited at Tire Expo 2013, to be held from February 5-7 in Cologne, Germany.
