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
Snijmolen 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.
Ideaal voor lichte & warmte-gevoelige materialen
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.
- Efficiënte koeling van monster en maalwerktuigen
- Verbeterde monster-uitvoer uit de maalkamer
- Bijzonder geschikt voor grote volumes
- De cycloon is geschikt voor monsterflessen van 0,5 - 1 - 2 - 5 liter en een container van 30 liter
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.
Snijmolen SM 200 Makkelijke Bediening & Reiniging
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.
Snijmolen SM 200 Toebehoren voor veilige en efficiënte maalprocessen
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.
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.
Trechter 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.
Bodemzeven
De bodemzeven zijn van roestvrij staal en zijn beschikbaar met rasp-vormige en vierkante gaten.

Snijmolen SM 200 Principe
Het malen in de snijmolen SM 200 gebeurt door snij- en scheerwerking. Het monster komt in kontakt met de rotor en wordt gemalen tussen de messen op de rotor en de dubbelsnijdende tegenmessen in de wand van de maalkamer.
Bij de 6-schijvenrotor zorgen 18 trapsgewijze geplaaste mesjes voor een optimale maalwerking. De messen op de parallel-rotor zorgen de evenwijdig geplaatse messen voor een krachtige werking. De verblijftijd in de maalkamer is kort; zodra het gemalen materiaal kleiner is dan de mazen van de bodemzeef, verlaat het de maalkamer naar het opvangrecipiënt.
De rotorsnelheid van 1500 toeren/min zorgt voor regelmatige en snelle maalactie. De optionele cycloon helpt niet enkel bij het koelen, maar verbetert ook het uitdragen van lichtere materialen en kleine volumes uit de maalkamer.
