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
커팅 밀 SM 200 Superiority in Detail
The SM 100 can be equipped with different rotors, hoppers and bottom sieves. The mill and accessories, including cutting bars and cutting plates, are also available in versions for heavy-metal-free size reduction.
광 & 열 민감성 시료에 이상적
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.
- 시료 및 절단 도구의 효율적 냉각
- 개선된 분쇄실의 시료 배출
- 대용량에 특히 적합
- 사이클론은 0.5 / 1 / 2 / 5 및 30 리터 시료 용기 장착 가능
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.
커팅 밀 SM 200 간편한 운영과 세척
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.
커팅 밀 SM 200 안전 및 효율적 분쇄 공정을 위한 액세서리
The SM 200 can be equipped with different rotors, hoppers and bottom sieves. The mill and accessories, including cutting bars and cutting plates, are also available in versions for heavy-metal-free size reduction.
로터 유형
A parallel section rotor and a 6-disc rotor are available in stainless and heavy-metal-free steel for optimum adaptation to sample properties.
호퍼 유형
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
The bottom sieve는 스테인레스 스틸 재질로 되어 있으며 사다리꼴 및 사각형 공극으로 제작됩니다.

커팅 밀 SM 200 작동 원리
커팅 밀 SM 200의 분쇄는 절단 및 전단력에 의해 발생됩니다. 시료는 로터와 접촉 후 칼날과 하우징에 삽입된 고정 커팅 바 사이에서 분쇄됩니다.
6 디스크 로터는 가역 가능 경질 금속판이 나선형으로 배치되어 순서대로 절단에 사용됩니다. 수평 날 로터의 칼날은 강력한 절단력으로 분쇄를 수행합니다. 분쇄실에서의 시료 체류 시간은 매우 짧습니다. 시료가 bottom sieve의 공극을 통과하기에 충분히 작아지면 즉시 배출되어 용기 내에 수집됩니다. 로터 속도 1,500 min-1은 부드러우며 빠른 분쇄를 보장합니다. 선택 사항인 사이클론 흡입 조합은 시료의 냉각 효과와 분쇄실의 시료 배출을 향상시킵니다.
