Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. Within the group of RETSCH cutting mills, the SM 200 is the universal standard model which covers a vast range of applications.

It is equipped with a strong 2.2 kW motor and operates at a rotor speed of 1.500 rpm. In combination with the optional cyclone-suction-combination, the SM 200 is also suitable for, grinding light or heat sensitive sample materials. A heavy-metal-free version is available to avoid cross-contamination. 

For universal applications

  • Feed size <60 x 80 mm
  • Defined final fineness due to bottom sieves with aperture sizes from 0.25 - 20 mm
  • Optimum cutting effects thanks to double acting cutting bars
  • Quick and easy cleaning due to smooth surfaces, fold back hopper, push-fit rotor and sieves
  • Operation with gravity outlet or optionally available cyclone unit possible
  • Wide range of accessories including various hoppers, collection systems, rotors and sieves
  • Highest safety standards due to engine brake, central locking device, electronic safety check and safety base frame

Ideal for light & heat-sensitive materials

Instead of the gravity outlet, an optionally available cyclone separator can be connected to the SM 200. The use of the cyclone-suction-combination is advantageous, for example, for light and heat-sensitive samples. 

  • Increased throughput
  • Improved sample discharge from the grinding chamber
  • Efficient cooling of sample and cutting tools
  • Collecting vessels with 0.25 - 0.5 - 1 - 2 - 5 and 30 liters are available for the cyclone unit

Double acting cutting bars

Double acting cutting bars

The SM 200 is equipped with double acting cutting bars which substantially increase the number and effectiveness of the cutting events. The parallel section rotor, for example, generates 18 cutting events per rotation.

Operation of the SM 200 is exceptionally simple and safe. A safety switch prevents the mill from being switched on with the door open. An electronic safety check ensures that the door cannot be opened when  the motor is running – the motor brake makes the rotor come to an immediate standstill after the mill has been switched off.

The hopper can be folded back to get full access to the grinding chamber which, in combination with the smooth surfaces, greatly facilitates cleaning the mill. The push-fit rotor can be removed without tools.

Rotor Types

Rotor Types

A parallel section rotor and a 6-disc rotor are available in stainless and heavy-metal-free steel for optimum adaptation to sample properties.

Hopper Types

Hopper Types

The SM 200 can be equipped either with the universal hopper, which is suitable for most samples, or the long-stock hopper which is specially designed for long samples.

Bottom Sieves

Bottom Sieves

The bottom sieves with trapezoid or square holes are made of stainless steel or heavy-metal-free steel.

Режеща мелница SM 200 Принцип на работа

Намаляването размера на частиците в режещата мелница SM 200 се извършва с помощта на силите на срязване. Пробата се смила между ножовете на ротора и неподвижните двойно-действащи ножове на статора.

В 6-дисковият ротор са инсталирани спирално последователно твърди пластини с режещи накрайници. Ножовете на паралелния ротор са по-мощни и раздробяват пробата с усилен режещ ефект. Времето за смилане е много кратко; след като пробата стане по-малка от отворите на дънното сито, тя преминава през него и се събира в колектора.

Скоростта на ротора от 1.500 об./мин. подсигурява внимателно и бързо маналяване големината на частиците. С помощта на опцията Циклон пробата може да се охлади допълнително, както и да се ползва за по-бързо отвеждане на смояната проба от смилащата камера.
