Mode of Operation
High-Speed Mixers Typ TSHK, operate on the principle of friction mixers. Due to the geometry of the mixing container, in coordination with specially shaped mixing elements and optimal speed, the mixing product is accelerated both radially to the outside and in an upward spiral to produce a clearly defined  vortex. The three dimensional product movement, with intensive friction, heats the entire batch gently and uniformly in the shortest possible time. The selection of mixing elements depends in each case on the field of application. Product heated in this way is cooled gently within the cycle by downstream vertical (KGU) or horizontal (HKB) cooling mixers designed for each project in accordance with the user specification.

TSHK/KGU Heating cooling combination (Horizontal cooler)

In the vertical KGU cooler, a three-arm mixing element rotates close to the wall with minimum clearance from the bottom of a vertical mixing container. The special shape of this element and its peripheral speed are coordinated in such a way that the mixing product is circulated as a vortex and thereby accelerated horizontally and vertically. This mode of product movement assures rapid, intensive mixing, even in the case of components with widely varied rheological features or mass fractions. If necessary, a separately driven chopper backs up the mixing effect and disperses lumps.

In the horizontal HKB cooler, Ploughshare® shovels rotate in special arrangement along the horizontal shaft inside a horizontal, cylindrical mixing drum. The size, number, positioning, geometric shape and peripheral speed of the mixing elements are coordinated for three-dimensional movement of the components inside the mixing drum. The resultant turbulence, with constant, total product mobility caused by the mixing elements, prevents the formation of dead or static zones and results in precision mixing within the shortest possible time.
