TwinFlo Prime

The rotor and shaft move together in the axial direction (eliminating any relative motion and preventing contamination of the sliding surface) The fixed connection ensures reliable operation without sensitivity to scaling and eliminates wear on the spline shaft. As a result, rotor jamming is effectively prevented, delivering enhanced durability and stability of the refining action.

Engineered for lowest pressure loss and consistent refining performance, the system features tangential feed and discharge lines that minimize turbulence and flow resistance. A fully symmetrical process design with a dual outlet ensures stable operation and precise control of both refining zones. The optimized flow geometry delivers maximum efficiency and uniform refining results.

Featuring advanced rotor port design with 70% larger openings, compared to conventional refiners and the system ensures optimal pulp distribution to both refining zones. The improved hydraulic conditions enable an even fiber split and consistent refining action, resulting in uniform performance. This balanced flow significantly reduces uneven wear of refiner plates and extends service lifetime.

This bearing technology makes the extremely compact design of the new Prime refiner possible and enables the rotor and shaft to float freely in the axial direction. This leads to a 30% reduction in refiner length and results in a substantial increase in possible energy input, enabling higher overall process performance in a single unit compared to the current TwinFlo refiner.

The symmetrical housing design stabilizes both refining zones and ensures identical performance on each side. The precise refining gap, combined with a shorter, more rigid shaft, improves refining quality while minimizing wear. This results in extended plate lifetime, reduced shutdowns, and consistently reliable operation.

The TwinFlo Prime is suited to all LC refining applications regardless of the raw materials and process set-up used.
