Smart.

The Fluxion Mixer is the smart choice of processors in todayÕs economy because it meets the cost reduction demands from global competition and because it provides the ability to perform low shear, high intensity mixing of polymer blends and of multiple polymers in recycling.

Economic & Efficient.

The Fluxion Mixer allows processors to color polymers in-house by blending natural resin with color concentrates at the machine or injection lines, thus allowing processors to reduce costs, implement new colors quickly and better control a wide ranges of colors.

Versatile.

When used for injection molding, the Fluxion MixerÕs design can incorporate a non-return valve. This eliminates the valve as a separate component and increases the available mixer length, a significant advantage since many injection machines offer limited screw length.

Flow Path

A row of radial rings divides the Fluxion Mixer sleeve into sections. Each section has a series of perpendicular holes that extend through the sleeve base, as shown below. The radial rings prevent material from flowing directly into an adjacent section. As material enters the first section, it is forces through the series of holes in the sleeve towards the rotor. The rotor outer diameter has corresponding grooves or slots that transfer the material under the ring and into the next section of the sleeve. This flow pattern is repeated a number of times until the material exits the mixer. Fluxion Flowpath

High Level Mixing at a Reduced Cost

A low shear floating sleeve cavity transfer type mixer. Random speed of sleeve rotation yields random mixing. Right angle flow paths from rotor to dynamic stator and back to rotor create maximum flow diversion.

Design

The Fluxion Mixer consists of a rotor and a dynamic stator (sleeve). The rotor can be machined as an integral part of the screw or supplied as a separate piece. The sleeve is a ring that is fitted over the rotor, allowing it to ÒfloatÓ in the barrel and rotate at much lower revolutions per minute than the rotor. This difference in velocity creates a complete random transfer of material between the rotor and the sleeve, which produces a high degree of distributive mixing. Dynamic Stator

Mixing Study

A major material supplier performed a study to compare the mixing performance of a conventional injection screw fitted with a standard non-return valve (NRV) and a Fluxion Mixer NRV, with a BARR Energy Transfer screw fitted with the same configuration. The goal of this study was to experimentally evaluate the mixing performance of the different hardware configurations at high color concentrate let down ratios. The table below summarizes the results. The results indicate that the Fluxion Mixer significantly improves the mix qualitym regardless of the type of screw used, without impacting the melt temperature or processing performance.
