New Cyclone Mill for Sample Preparation to NIR Analysis

Retsch’s new cyclone mill TWISTER is specially designed for the processing of foods and feeds for subsequent NIR analysis. The optimised form of rotor and grinding chamber generates an air jet, which carries the ground sample through the integrated cyclone into the sample bottle.

The air jet prevents the material from heating up, thus preserving the moisture content. The provided sieves guarantee an optimum particle size distribution so that it is not necessary to recalibrate the NIR spectrometer.

The rotor speed can be adjusted in three steps allowing for perfect adaptation to the sample requirements. Cleaning the mill is quick and easy as the air jet affects a complete discharge of the material from the grinding chamber.

This new cyclone mill in proven RETSCH quality optimises the reproducible sample preparation to NIR analysis thus allowing for meaningful and reliable analysis results.

Advantages include: ideal for grinding feeds, grains, forage and similar products; three controlled speeds; including rotor, grinding ring and sieve sections (1mm and 2mm); cyclone separator with 250ml collecting bottle for quick extraction of sample; no cross contamination thanks to easy cleaning; convenient operating panel; and professional industrial design with long lifetime.
