OscilloWitt - the oscillating and rotating sieve mill for gentle size reducion
Excellent for narrow grain size spectrums and the grinding of heat sensitive products<xml></xml>
The oscillating and rotating sieve mills of the OscilloWitt series are especially suited for the size reduction of heat-sensitive products and products that are difficult to process.
The OscilloWitt has been fundamentally redesigned and this results in a substantial increase in utility. The product is gently reduced in size through the infinitely adjustable oscillating or rotating rotor movement, the ever-constant speed and the force exerted. During the milling process, the granules are gently moved through the sieve openings, which reduce the heating of the product to a minimum.
The OscilloWitt sets new standards in terms of modularity, ease of operation and facility of maintenance. It also provides more power and offers an enormous flexibility at a lower cost.

PROCESS
PROCESS
The OscilloWitt consists of a rotor, sieve, sieve tensioner or rigid screen support. The oscillating or rotating cyclical movement causes the passage of the product through the sieve. The functionality of the OscilloWitt and the applied use of the milling forces are particularly suited to the gentle milling of products that are heat-sensitive and difficult to process, and the production of narrow grain size spectrums tolerances without fine materials.
Milling forces
Comminutation in the OscilloWitt is achieved primarily by shearing and comminutation of the particles between the sieve and the oscillating or rotating rotor at a relatively low level of force.

APPLICATIONS
APPLICATIONS
A particle sizing system in universal application
The redevelopment of the OscilloWitt makes "Frewitting" even more successful. Both dry and wet products, as well as those that are heat-sensitive and difficult to process, can be reduced in size and dosed
The OscilloWitt can be used for the production of small quantities, as well as for large-scale production in batch or in-line operations, as standard or customized execution in the pharmaceutical, fine chemicals and food industry.
The OscilloWitt is reliable in processing and fast in processing, protecting the user, as well as the product and also ensures a reduction in production costs. The OscilloWitt - a sieve mill of a very special kind, able to grow with your needs
CONSTRUCTIONS
CONSTRUCTIONS
The OscilloWitt consists of a rotor, sieve, sieve tensioner or rigid screen support.
- Inlet funnel with a protective grill
- Security check at the inlet funnel and doors (default) no external cable
- Large selection of different sieve types (round wire/square wire/rasp and perforated plate)
- Sieve tensioner for direct tensioning of the sieve (classic mode of operation)
- The use of the rigid sieve support and the correct adjustment of the distance between the rotor and sieve prevents contact between metal parts
- Rotor with six bars
- Relevant process parameters can be seamlessly documented
- O-ring seal on doors for highest level of containment
- LCD speed display in M / Sec
- Sieve with round wire for the size reduction of products that are easy to break down
- Sieve with square wire for hard products / fine sieves for wet grinding
- Multi-function mill thanks to quick setting of the milling process to oscillating or rotating
Control options
Control options
Option: Pack 1
Variable rotation / oscillation speed
Switching from rotation to oscillation
Oscillation with a superimposed light rotation ensures that the rotor is used uniformly on all sides. Thus a longer operating life is possible.
Option: Pack 2
Changing the oscillation amplitude via a potentiometer.
Greater angle in the milling area
Oscillation with a superimposed light rotation ensures that the rotor is used uniformly on all sides. Thus a longer operating life is possible.
