It works, but durability could be better.
Food ANALYSIS
The product is effective in grinding food samples. It achieved high quality and is easy to use. However, after a few years of service, it has issues when it starts and goes through self-check cycle. It fails to start from time to time, and has to be restarted repeatedly.

Cutting mills are suitable for the grinding of soft, medium-hard, elastic, fibrous, and heterogeneous mixes of products. The new cutting mill SM 200 is a powerful and easy-to-operate instrument for efficient primary and fine size reduction. Cleaning is made particularly easy. Within the group of the RETSCH cutting mills, it is the universal standard model which covers a vast range of applications with its strong 2.2 kW drive and 1,500 rpm rotor speed. Instead of the gravity outlet, an optionally available cyclone separator can be connected to the SM 200. The use of the cyclone is advantageous, for example, for light and heat-sensitive samples. In combination with the wide choice of bottom sieves, hoppers and collecting vessels, the mill can be easily adapted to varying application requirements.
PRODUCT ADVANTAGES
- feed size < 60 x 80 mm
- powerful size reduction with 2.2 kW drive
- optimum cutting effects thanks to double acting cutting bars
- 18 cutting events per rotation with parallel section rotor
- quick and easy cleaning due to fold-back hopper, smooth surfaces and push-fit rotor
- maximum peripheral rotor speed 9.4 m/s
- defined final fineness due to bottom sieves with aperture sizes from 0.25 - 20 mm
- 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
Optimized grinding process for smaller sample quantities
Efficient and reproducible sample preparation is a critical prerequisite for high-quality analytical results. However, laboratories working with low-mass or irregular sample types—such as individual children's toys for hazardous substance analysis, lightweight feather samples, or small herb batches—often encounter limitations with conventional cutting mills.
Existing systems either suffer from significant sample loss due to oversized designs or lack the necessary throughput and power to process more demanding materials effectively.
In this appplication note, Retsch describes how its SM 50 Cutting Mill combines the compact footprint of bench-top devices with the performance capabilities of full-sized floor-standing mills. Central to its design is the Total Access Concept—a pioneering approach that integrates:
- EasyInspect for rapid and thorough visual inspection
- Push-fit modularity enabling quick assembly and tool-free configuration
- EasyClean allowing uncompromised, efficient cleaning to minimize cross-contamination
