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
•t 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.
•t 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.
•t xcellent feeding of warm rubber strips from the two-roll mill by the
E
independently driven and controlled TRF.
•t mall footprint for simple integration into existing mixing lines without
S
additional operators.
