Machine type designation: Cyclone Mill - Twister
This machine is intended for the grinding of animal feed, green feed, cereals and
similar dry materials.
The feed size is 10mm.
The device is designed as a laboratory device for 8-hour one-shift operation with a
30% ON duration.
It is not intended for use as production machine.

This device has been developed to prepare samples of animal feed for final NIR
analysis. The optimised form of the rotor and of the grinding chamber generates an
air current which transports the ground material through the integrated cyclone
into the sample vessel. The air current simultaneously prevents the warming of the
sample so that moisture losses are avoided. The sieves supplied guarantee
optimum particle size distribution. The rotor speed can be adjusted in 3 stages and
can therefore be adjusted to the requirements of the sample. The cleaning

requirements are very low in this device because the sample is transported virtually
completely from the grinding chamber.
Advantages at a glance:
•Ideal for the grinding of animal feed, green feed and similar materials
•3 controlled rotor speeds
•Cyclone with 250 ml collecting receptacle for fast collection of samples
•Simple and fast cleaning, no cross-contamination
