Abstract

The present invention is directed to a mixer for mixing at least two free-flowing, reactive or unreactive substances comprising PA1 (a) a casing having at least two inlets and at least one outlet, PA1 (b) a rotatable shaft extending through the casing, PA1 (c) at least one rotor disc attached to the shaft such that the rotor disc is perpendicular to the shaft, PA1 (d) at least one stator disc attached to the casing such that the stator disc is parallel to the rotor disc and has an opening such that shaft can pass through the stator disc, PA1 (e) optionally at least one running wheel attached to the shaft and containing openings such that when the shaft is rotating, the running wheel provides a pumping effect to the mixture passing through the mixer, PA1 (f) at least one inlet through the casing for introducing a first substance axially to the shaft and against the rotor disc and PA1 (g) at least one inlet for introducing a second substance against a rotor disc at a point which is radially outward from the introduction of the first substance.
