Technical data

CAUTION

1.V0004

Risk of explosion or fire

Changing sample properties – Consider that the properties and therefore also the hazardousness of your

sample can change during the grinding process.

• Do not use any substances in this device which carry the risk of explosion or fire.

CAUTION

Risk of explosion or fire

– On account of its design, the device is not suitable for use in hazardous

(potentially explosive) atmospheres.

• Do not operate the device in a hazardous atmosphere.

CAUTION

Danger of personal injury

Dangerous nature of the sample – Depending on the dangerous nature of your sample, take the

necessary measures to rule out any danger to persons.

• Observe the safety guidelines and datasheets of your sample material.

Target group: operators 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.

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

Technical data

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
