ELASTOMER ROLL-EX® EXTRUSION SYSTEM The roll-ex® extrusion system from Uth GmbH is engineered for high-volume fine mesh rubber straining and for processes requiring high output stability. Modular in design and built with a smaller footprint, this system is widely used for mill room mixing or within a mixing line. The roll-ex® is capable of reducing scrap and producing higher quality rubber with minimal to zero defects. Models are available for processing .45 to 6 metric tons (990 to 13,000 pounds) per hour. At A Glance • Compact design and efficient operation. Up to 70 percent energy savings. • Stable temperature levels under high pressure. • Improved quality for specialty applications. • Simplified maintenance and improved material changeover cycle times. • High degree of amortization. www.davis-standard.com

ROLL-EX® EXTRUSION SYSTEM cont. SYSTEM ADVANTAGES Based on the gear pump principle, the roll-ex® system generates extrusion pressure by two interlocking rotors. Material is gently processed due to a short retention time within the unit and a constant temperature is maintained at pressures up to 500 bar. Due to the volumetric conveying process, the pressure is uniform to provide precise extrudate output. The minimal volume of the system reduces the amount of waste when changing over compounds, and limits energy demand which is up to 70 percent less when compared to that of a single screw...
