Rotary sifter TurboWitt
High flexibility and optimum disagglomeration results
The TurboWitt is especially well-suited for the disagglomeration and homogenisation of hard and soft products. The range of applications of this rotary sifter make it very polyvalent utile for the Pharma-, fine chemical or food industries. Milling in the TurboWitt is achieved primarily by the particles being suspended and comminutated between the drum surface and the stator. Centrifugal forces act on the product, causing it to flow gently under the two fix-mounted stator arms pressing, through the sieve openings. Due to process the granulometry of the product hardly changes, and the fine particle fraction remains optimal. The size, shape, and distribution of the grains are determined by the type of sieve, sieve opening, speed of the sieve drum rotation, and the distance between stator and sieve. It’s flow rate is variable, from ca. 1000 kg/h to 25’000 kg/h. The secret of the success lies in the fact that the TurboWitt can be easily converted within minutes into a conical sieve mill and just as easily back into a TurboWitt.

Construction
Construction
Due to its modular construction, this sizing mill is ready to operate in no time.
- The sieve or rasping drum and the stator are easily installed or
removed without tools.
- Easy and quick cleaning (WIP)
- Tri-Clamps for attachment of the inlet and outlet funnels
- Continuously variable, manual (hydraulic) height adjustment

Process
The TurboWitt milling process
Centrifugal force acts on the product, causing it to flow gently under the two fix-mounted stator arms, through the sieve openings. Milling in the TurboWitt is achieved primarily by the particles being held and comminutated between the drum surfaces and the stator.
In Contrast to systems with rotary milling tools, the TurboWitt foreign products are excluded from the milling process and easily removed during the controlled sieving process.
