Laboratory Cutting Mill
Model SM 100

The cutting mills reduce soft, medium-hard, elastic and fibrous materials fast and with minimum damage to the substance. They are particularly suitable for preliminary pulverization of dry materials such as plant parts, plastics, fodder, spices and drugs, lignite, paper, cardboard, etc.
Long-fiber goods such as straw and large volume items such as plastic cups can be prepared in a single step, without preliminary chopping. Maximum feed item size for thinwalled plastic containers, for example, is 60 x 80 mm when using the standard hopper. Ultimate fineness is dependent in each case on the bottom screen used and the nature of the product. When handling plastics, for example, this may be between 2 and 4 mm whereas dry spices can be pulverized to as small as 0.25 to 1 mm.

ADVANTAGES
  • Fast pulverization with minimum damage to the product

  • Three hopper models for a variety of materials
  • Low thermal loading for the product
  • Low-dust pulverization
  • Cutting elements easily replaced
  • Design complies with CE requirements for superior safety
  • Ttwo-year-warranty

SM 100 TECHNOLOGY
Size reduction inside the cutting mill is effected with cutting and shear action. The feed product passes through the hopper and into the grinding chamber. There it is engaged by a rotor fitted with 3 knives and is reduced between these blades and the cutting strips inserted in the housing. The dwell period inside the grinding chamber is short; as soon as the product is reduced to a size smaller than the perforations in the bottom screen it is discharged for collection in the container. Rotor speed at 1430 r.p.m. at 50 Hz ensures fast and gentle pulverization with a minimum of dust. The motor is rated at 1500 watts.
The fine product is quickly discharged thanks to the use of a filter bag or ring-type filter. The housing for the mill is made of aluminum. The hopper, rotor, motor flange, door insert, 5-liter receiver and the bottom screen are made of stainless steel. The 30-liter receptacle is made of plastic. The knives are made of a special-alloy steel (12 % Cr), the cutting bars of stainless steel (14.5 % Cr). The door for the mill housing is opened with a key; a safety switch shuts off the motor before the door is opened.
