Rotor-Stator Systems

Perfectly suited for the required task: Effective processing of each medium by application of shearing stress in the gap between rotor and stator using very high circumferential speeds (up to 54 m/s).

Always the best adaptation

High flexibility. Well proven. Excellent durability. Up to now, our systems have been used successfully in more than 6,000 processing plants featuring a vast number of modifications. A broad selection of different materials ensures an adaptation with optimised service lives. For the selection of the suitable rotor-stator system an intensive product evaluation is required: Characteristics such as density, degree of hardness, consistency and composition have to be evaluated. Temperature sensitivity, agglomeration behaviour or surface reactions can also affect on the correct configuration to achieve the desired processing result. While hard to brittle products can be crushed by impact, pressure and friction, soft and elastic materials can often be reduced only by cutting and shearing effects. If necessary, a patented silhouette arrangement of the tooth flanks allows a unique cutting effect for the size reduction of elastic media.

With power and precision – the special functional principle

The core of each of our machines is characterised by its variable structure: Rotor and stator consist of up to four coaxially arranged rotor and stator rings (stages) each. They each have a toothed design and feature radial channels and/or bores. The number of channels as well as their shape, width, depth and alignment varies. Rotor and stator can be arranged either planeparallelly
or step by step.
The resulting vast selection of different rotor-stator systems allows the Trigonal®-Machine to always be optimally adapted to the required task.

The unique operating principle of our systemsquerschnitt-maschine
The medium initially enters the centre of the rotorstator system in an axial direction and is centrifugally accelerated towards the outside (“forced feeding through the gap”). The medium has to pass through up to four stages. During this process the medium is continually exposed to various physical effects:

  • Separation of the medium into many separate currents
  • Frictional, shearing, cutting and/or impact loads
  • dden acceleration and deceleration of the medium, which cause shock pressure waves with compression and decompression processes, which then cause micro-activities
  • Turbulences transfer their frictional processes onto the medium.

These following effects can be further adjusted by changing the geometry and alignment of the slots (in or against the flow direction), by changing the speed and flow rate, as well as by changing the infinitely adjustable gap size between stator and rotor. As neither rotor nor stator have a continuous channel, no particle passing through the machine remains unprocessed!
