Roll-ex Gear Extruders - Fine Mesh Straining - 1

ELASTOMER ROLL-EX® FINE MESH RUBBER STRAINING It has been proven that the quality of rubber compounds can be improved significantly by fine mesh straining. The Davis-Standard and Uth roll-ex® gear extruder with TRF (two-roll feeder) technology provides an economical and efficient processing option. The roll-ex is engineered for straining applications of accelerated compounds because of its non-aggressive material treatment. Modular in design, this extruder can also be used in a single step together with the mixing process for a cost-effective solution. At A Glance • wo-roll feeder (TRF) integrates processing part and strainer head into a compact T two-stage unit, which is linked to the fine mesh straining of warm material. • ow temperature increase when using fine mesh screens and high pressure up L to 500 bar because of gear pump characteristic and TRF feeding combination. • xcellent feeding of warm rubber strips from the two-roll mill by the E independently driven and controlled TRF. • mall footprint for simple integration into existing mixing lines without S additional operators. www.davis-standard.com
