Knife Mill GRINDOMIX GM 200

Knife Mill GRINDOMIX GM 200

In food or nutritional laboratories, in chemical or biological research institutes – suitable sample material is required everywhere for the accurate analysis of food and feed materials. With the Grindomix GM 200 knife mill, RETSCH has designed a size reduction and homogenisation instrument that meets and exceeds all special laboratory and analytical requirements. It can process substances with a high water, oil or fat content just as quickly and reliably as dry, soft and medium-hard products.

Application Examples

cheese, deep-frozen products, feed pellets, fish, food, fruit, ham, meat, pharmaceutical materials, plant materials, sausages, seeds, spices, vegetables, ...

Function Principle

Two straight knives, which are arranged at different heights at right angles to the direction of rotation, rotate in the center of the grinding vessel. The sharp and slim steel blades comminute and homogenize reliably. In order to protect them from damage by hard sample material, they are provided with a counterblade. The powerful industrial motor with its 750 W continuous rating (1200 W for short periods) drives the knives directly. Pre-selectable speeds, held constant by the electronics, ensure that even difficult samples are comminuted and homogenized in only 10 to 30 seconds.
