Add-on mixing device improves screw performance

A new floating ring mixer utilizes a rotor and dynamic stator to fully re-orient the melt for a high degree of mixing without adding excess shear. Each stator and rotor element consists of a series of holes or slots that are located parallel to the axis of the screw. The rotors are fixed to a central shaft and rotate with the screw. The dynamic stators are located between each rotor and are not allowed to rotate at the same velocity as the screw due to the clearance of the stator and barrel inside diameter. The material enters axially through the holes in the rotor and is only able to transfer to the stator when momentary alignment of the holes occurs. The degree of mixing can be controlled by the number of elements that are added to the end of the screw. This modular approach to mixing allows the molder to have complete control over the process.
