Retsch Knife Mill GRINDOMIX GM 300, 220–230 V, 50/60 Hz
Complete with grinding container 5 litre of autoclavable plastic, standard lid, knife and scraper

The new knife mill GRINDOMIX GM 300 is the ideal instrument for the grinding and homogenization of foodstuffs. It allows to process sample volumes up to 4.5 liters quickly and reproducibly.

With four sharp, robust blades and a powerful motor which can reach temporary peaks of 3 kW, it is ideal for homogenizing substances with a high water, oil or fat content as well as for grinding dry, soft and medium-hard products. The GRINDOMIX GM 300 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.

Application Examples:
candy, cereal bars, cereals, cheese, coated tablets, cocoa nibs, deep-frozen products, dietary supplements, dried and fresh fruit, feed pellets, fish, ham, lettuce, meat, nuts, ...

Product Advantages:
- Efficient size reduction of up to 4,500 ml feed quantity due to a powerful 1.1 kW motor (peak power input >3 kW)
- Pre- and fine-grinding in one mill: cutting action in regular mode, grinding by impact in reverse mode, pre-grinding in interval mode
- All parts which come into contact with the sample material are autoclavable
- Perfect adaptation to application requirements by variable speed from 500 to 4000 min-1 with an increment of 100 min-1
- Optional gravitation lid for automatic reduction of the grinding chamber volume
- 10 SOPs can be stored
- Grinding jar in plastic and stainless steel available

Function Principle:
Four 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 knifes are protected with a counterblade from damages by hard sample materials.

The knife is indirectly driven by a powerful motor of 1,1 kW which can reach temporary peaks of 3 kW. A pre-selectable speed which is maintained electronically ensures reproducible grinding results.

Knife Mills GRINDOMIX GM 200 / GM 300
The Knife Mills Grindomix GM 200 and GM 300 are suitable for the rapid and reproducible size reduction and homogenisation of food and feed materials. They can process substances with a high water, oil or fat content just as quickly and reliably as dry, soft and medium-hard products.

Features:
-Very fast and reproducible grinding and homogenisation of foodstuffs, final fineness < 300 µm
-Speed-controlled industrial motor
-Autoclavable grinding tools
-For sample volumes up to 700ml (GM 200) or 4500ml (GM 300)
-Digital display of grinding time and speed
-Interval operation possible
-Optional gravity lid for automatic adjustment of grinding chamber volume
-10 parameter combinations can be stored (GM 300)
-Drive power : ~ 900W (GM 200); continuous 1.1kW, short term peak 3 kW (GM 300)
-Electrical supply data: 220-240V, 50-60Hz
