Cutting mills are the first choice for the size reduction of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products.
The SM 100 is the budget-priced basic model among the RETSCH cutting mills. It is suitable for the size reduction of samples which don’t require extremely high forces. The mill has been specially designed for routine applications. It is easy to operate and can be mounted on a solid table or on the optional base frame.

For routine applications
- Feed size < 60 x 80 mm
- Defined final fineness due to bottom sieves with aperture sizes from 0.25 - 20 mm
- Quick and easy cleaning due to smooth surfaces and push-fit rotor
- Gravity outlet for collection vessels of different sizes
- Wide range of accessories including various hoppers, collection systems, rotors and sieves
- Highest safety standards
Cutting Mill SM 100 Accessories for safe and effective grinding processes
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.
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
The SM 100 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 sieves with trapezoid or square holes are made of stainless steel or heavy-metal-free steel.

Cutting Mill SM 100 Functional Principle
Size reduction in the Cutting Mill SM 100 takes place by cutting and shearing forces. The sample comes into contact with the rotor, and is comminuted between the blades and the stationary standard cutting bars inserted in the housing. In the 6-disc rotor, spirally arranged reversible hard metal plates operate by cutting in sequence. The knives of the parallel section rotor carry out comminution with a powerful cutting action. The dwelling time of the sample in the chamber is short; as soon as it is small enough to pass through the openings of the bottom sieve it is discharged through the gravity outlet and collected in the receptacle. The rotor speed of 1.500 min-1 ensures gentle and rapid size reduction.
