TORE® is a compact, one-piece construction with no moving parts. A central discharge tube is enveloped by a swirl chamber, which tapers down to an outer tube, creating an annulus with the discharge tube. An inlet tube connects tangentially to the swirl chamber. A specially designed flange or foot is attached outwardly on the discharge pipe.

How TORE® works
Liquid is fed, or pumped, into the swirl chamber through the inlet tube. It then accelerates through the tapered section, continuing to swirl along the annulus section, before exiting both radially and axially out over the “foot”, creating a vortex.
This vortex known as a precessing vortex core (PVC) is a 3-dimensional time-dependant instability, which lies directly beneath the discharge tube. When it occurs, the central forced vortex region of the flow becomes displaced from the axis and starts to precess about the axis of symmetry.
The frequency and amplitude of precession are both regular, which is known to encourage fluidising of solids. The precessing vortex core lifts the fluidised solids, swirling like a tornado, up through the discharge tube. This motion creates a liquid boundary layer between the slurry being discharged and the internal pipe wall, eliminating erosion in the discharge pipe.
