IKA - SIEFER TRIGONAL®- Machines
The TRIGONAL®- Machine - Functional Principle
SIEFER developed and supplies the TRIGONAL®- machine, a high shear mixer for wet size reduction.
The TRIGONAL®- machine operates on the flow method, functioning in accordance with the principle of kinematic high frequency technology. The material to be processed enters the center of the rotor-/stator-system axially and is centrifugally accelerated.
The size reduction is the result of shearing stress in the gap between rotor and stator. The intensity of processing is decisively affected by the rotor-/stator-system that is selected.
Currently, over 420 combinations are available which are individually adjusted to the medium and the end product.
The comminution zone is of stepped construction. As many as four coaxial arranged operating rings can be placed one behind the other. Rotor and stator have a toothed design and feature crossover openings in the form of grooves with varying depths in a radial direction which we refer to as channels. As a result, the flow is deflected in each step, forcing feeding via the gap (between rotor and stator).
The medium is compressed in the channels between the tooth profiles of the rotor-/stator- system. 1/1000th of a second later the chamber opens because it meets the next-larger rotor ring, the medium relaxes abruptly and flows into the next channel away from the center. The dwell time of the product in the machine can be controlled by the respective arrangement of the tooth profiles of the rotor and stator. Due to a circumferential velocity which varies between 20 and 54 m/s, depending on the application, this process is repeated up to 500 million times per second.
The efficiency of the SIEFER TRIGONAL®- machines is the result of the different types of processing of the product taking place simultaneously:
- Division of the material being processed into a number of individual flows
- Reduction of the cross section of the groove and chamber when the product passes through the operating rings prepares it for the last and finest stage on the periphery.
- The medium in the chamber is either accelerated if there is a passage available when it meets the next-larger operating ring, or decelerated if there is no opening available. Acceleration and delay result in abrupt changes in pressure with decompression and compression processes thus creating microcavities.
- Due to the turbulences in the effective space, internal frictional forces are transferred to the product.
