The Perfect Cutting Mill for Every Requirement

The RETSCH cutting mills provide highly efficient primary size reduction of heterogeneous material mixes but are also suitable for grinding soft, medium-hard, elastic or fibrous samples. With the SM 100, SM 200 and SM 300 RETSCH offers three models for different requirements.

SM 100 – The Budget-Priced Basic Model

The SM 100 model is suitable for the size reduction of soft, medium-hard, elastic or fibrous products which can be comminuted without requiring extremely high forces. The mill is particularly suitable for routine applications. It is easy to operate and can be mounted on a solid table or on the optional base frame.

SM 200 – The Universal Standard Model

Within the RETSCH cutting mill family, the SM 200 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. It can be operated with the optional cyclonesuction- combination to improve, for example, discharge of low-density materials. The hopper can be folded back and the push-fit rotor and sieve are easily removed for cleaning without tools.

SM 300 – The High Performance Model with RES Technology

The SM 300 model is characterized by a high torque, maximum cutting effect as well as safe and convenient operation. To allow for optimum adaptation to the sample properties with regards to breaking behavior and temperature sensitivity, the SM 300 features a variable speed from 700 min-1 to 3,000 min-1. Thus it is possible to grind a great variety of products with one mill, including tough and thermally sensitive materials. An additional flywheel mass provides exceptional cutting power reserves, thus enabling the SM 300 to grind many materials to analytical fineness in only one working run (RES technology). The grinding chamber features an optimum geometry. The wide opening of the hopper and excellent feeding properties allow for large sample volumes, resp. pieces, thus increasing the throughput. Just like the SM 200, the SM 300 can be equipped with the cyclone-suction-combination which is especially recommended for fibrous, light sample stock.

The RETSCH Cutting Mills SM 200 and SM 300 excel especially in the tough jobs where other cutting mills fail. They offer a high degree of safety and longevity of the grinding tools.
