The knife mill GRINDOMIX GM 200 is the ideal instrument for grinding and homogenizing foods and feeds. With two sharp, robust blades and a powerful 1000 W motor, it allows to process sample volumes up to 0.7 liters quickly and effectively. 

The GM 200 is not only ideal for homogenizing substances with a high water, oil or fat content but is also perfectly suited for grinding dry, soft and medium-hard products. The quick homogenization process without noteworthy temperature rise ensures preservation of volatile sample components.

Thanks to reproducible setting of parameters, programs and sequences, this mill ensures analytical results with minimum standard deviation. These features plus the wide selection of lids and containers, allowing for adaptation of the mill to individual application requirements, make the GRINDOMIX GM 200 a professional device superior to any commercial household mixer.

Knife Mill Grindomix GM 200 - Technical Data

Knife Mill Grindomix Gm 200 Cryogenic Grinding With Dry Ice

To process tough or elastic materials which cannot be homogenized at room temperature, a Cryokit is available to ensure safe and efficient grinding with dry ice. It consists of three components:

  • Cryo lid

The lower part is made of stainless steel, the side openings allow for evaporation of CO2 during cryogenic grinding; the upper part is the standard PP lid.

  • Stainless steel container with baffles

The baffles contribute to a thorough mixing of the sample.

  • Full metal knife

This knife has 4 blades and is a must for cryogenic grinding. It is also well-suited for cutting hard samples. 

Knife Mill Grindomix Gm 200 Easy And Safe Operation

The GM 200 is equipped with a 4.3’’ touch display offering easy parameter setting, SOP storage and direct access to the MyRETSCH web portal via QR code. 8 Standard Operating Procedures and 4 program cycles can be stored for routine operations. Before and after the grinding process, the container with its lid, inserted knife and sample, can be installed and removed as a complete unit.

Gravity Lid Enables Variable Volume Of The Grinding Chamber 

  • Patented gravity lid

Automatically adjusts the grinding chamber volume to the changing sample volume.

  • Gravity lid with overflow channels

Ideally suited to homogenize samples with a high water content.

  • Stainless steel container

Minimum wear when hard sample materials are processed.

  • Stainless steel container with baffles

The baffles contribute to a thorough mixing of the sample.

  • Reduction lid

Reduces the chamber volume to 0.5 or 0.3 liter for optimum homogenization of small sample volumes.

  • Serrated blade knife

Used for particularly tough samples such as fatty, streaky meat.

  • Full metal knife

With 4 blades, it is suitable for cold grinding and cutting hard samples.

  • Cryokit

For homogenizing sticky samples with dry ice


Knife Mill Grindomix GM 200 - Typical Sample Materials

Two sharp, robust blades rotate in the center of the grinding container. Depending on the rotational direction, size reduction is effected with the blunt side (preliminary size reduction) or the sharp side (fine grinding).

The knife is directly driven by a powerful motor of 1000 W. A pre-selectable speed which is maintained electronically ensures optimum adaptation to individual application requirements as well as reproducible grinding results.
