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:
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.
The baffles contribute to a thorough mixing of the sample.
This knife has 2 blades and is a must for cryogenic grinding. It is also well-suited for cutting hard samples.
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.
RETSCH has developed a gravity lid for the GRINDOMIX knife mills which reduces the volume of the grinding container, preventing the sample from escaping the homogenization process by clinging to the container walls. The lid drops under its own weight during grinding and always rests directly on the sample. The result is thorough homogenization of the complete sample material. The gravity lid is also available with overflow channels. It ensures that the cell liquid released by the sample during grinding is returned through these channels to the center of the container, allowing for perfect homogenization.
A range of different containers, lids and knives makes the GRINDOMIX GM 200 a truly universal device, suitable not only for processing food and feed samples but a wide range of materials.
Automatically adjusts the grinding chamber volume to the changing sample volume.
Ideally suited to homogenize samples with a high water content.
Minimum wear when hard sample materials are processed.
The baffles contribute to a thorough mixing of the sample.
Reduces the chamber volume to 0.5 or 0.3 liter for optimum homogenization of small sample volumes.
Used for particularly tough samples such as fatty, streaky meat.
With 2 blades, it is suitable for cold grinding and cutting hard samples.
For homogenizing sticky samples with dry ice
RETSCH knife mills are suitable for a vast range of applications. Typical materials include candy, cereals, cheese, coated tablets, cocoa nibs, dietary supplements, dried and fresh fruit, feed pellets, fish, frozen products, ham, lettuce, meat, nuts, oil seeds, pharmaceutical products, plant materials, sausages, soap, spices, vegetables etc.

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.
