Target group: operators Machine type designation: GM 200

This device is suitable for analytical grinding, homogenisation and mixing of soft to medium-hard, aqueous, fatty, fibrous and dry materials in seconds. This device is designed for quantities of approximately 700ml, large volume materials up to 1000ml.

The feed size is < 30 - 40 mm. The device is specially designed for the grinding of the following materials : Fish, meat, vegetables, cheese, preserves, seeds, bacon, sausage, dry baked

goods and pastries, all aqueous, fatty and fibrous products and similar materials. The device is designed as a laboratory device for 8-hour one-shift operation with a

30% ON duration. It is not intended for use as production machine and not intended for the mixing

and homogenisation of liquids with low viscosity (emulsions and suspensions) .

The grinding process of the device is effected through cutting and, in reverse operation, through impact effect.

The cutters are straight and are arranged at right-angles to the direction of rotation. The cutters are slim with a cutting angle of 15° and a pre-cut (pre-grind) of 30°. With this cutting geometry the entire inertia resulting from the speed difference

between the sample material particles and the cutters can be used as cutting force. The speed is between 2000 - 10000min-1 and is altered in stages of 500min-1 and

displayed digitally. The preselected speed is kept constant during grinding by a speed regulator. Interval operation has proved to be advantageous in the pre-grinding and

homogenisation of large-piece, tough, fibrous and very soft and elastic products. The grinding duration can be set up to 3 minutes. After expiry of the grinding

duration the motor automatically switches off and the housing lid opens. 3 memories permit the storage and retrieval of frequently used speed/time

The grinding chamber of this device is interlocked by a resistant protective hood. It is only possible to start the device when the protective hood is closed. The motor

must have come to a standstill to open the device. In the event of fault there is also an electric emergency brake which brings the

cutters to a standstill in fractions of a second from the highest speed. If the achievable current speed deviates from the setpoint speed by more than 5%
