RETSCH SM 200 Cutting Mill

RETSCH SM 200 Cutting Mill

The RETSCH Cutting Mill SM 200 is a universal and powerful instrument for the efficient size reduction of various materials. Whether you need to grind soft, medium-hard, elastic, fibrous or heterogeneous mixtures of products, this cutting mill is the right tool. For applications requiring mixing and homogenizing by pressure and friction, consider the RETSCH Mortar Grinder RM 200. The SM 200 can process materials up to 60 x 80 mm in size. It is designed for both primary and fine grinding and is suitable for many applications.

With its 2.2 kW strong drive and 1,500 rpm rotor speed the mill is the standard model within the RETSCH cutting mills family. It is suitable for larger quantities of sample material. The net weight of the SM 200 is designed for easy transport and installation. The protection code (IP rating) ensures dust and water protection for safety and durability. With the optional cyclone-suction-combination it is suitable for grinding light sample material or smaller quantities.

Cleaning the mill is easy and hassle free. The fold-back hopper, smooth surfaces and push-fit rotor make cleaning quick and thorough so you can always keep the instrument in perfect condition.

The cutting mill works on the principle of cutting and shearing forces. The sample is comminuted between the blades on the rotor and the stationary cutting bars. The 6-disc rotor with hard metal plates cuts in sequence. The parallel section rotor comminutes with a powerful cutting action.

The mill is highly adaptable to your application requirements. It can be easily adjusted to your needs with the wide range of bottom sieves, hoppers and collecting vessels. The standard hopper is included as a universal feeding component and is suitable for various sample sizes and types. This flexibility makes it the perfect choice for laboratories and research institutions that work with different sample materials.

In addition to its powerful grinding capabilities the mill offers many advantages. It ensures optimal cutting effects with double acting cutting bars, defined final fineness with bottom sieves of various mesh sizes and complies with the highest safety standards with features like engine brake, central locking device, electronic safety check and safety base frame.The RETSCH Cutting Mill SM 200 is a robust and efficient instrument for many materials and applications. Whether you work with aluminium slag, animal feed, cardboard, pharmaceutical products or wood, this cutting mill delivers precise and reproducible size reduction. It is suitable for hard, tough, elastic, fibrous, medium hard, tough, elastic, as well as soft, medium, hard, tough materials, so it’s versatile for many industries and applications.

Cutting mills are suitable for grinding soft, elastic, fibrous and heterogeneous mixtures of products. The new cutting mill SM 200 is a powerful and easy to operate instrument for primary and fine grinding. Cleaning is made very easy.

Within the group of the RETSCH cutting mills it is the universal standard model which covers a wide range of applications with its 2.2 kW strong drive and 1,500 rpm rotor speed. For different requirements, the RETSCH Ultra Centrifugal Mill ZM 300 offers advanced features for the rapid size reduction of a broader variety of materials. When operated with the optional cyclone-suction-combination the SM 200 is also suitable for grinding light sample material or smaller quantities. Together with the wide range of bottom sieves, hoppers and collecting vessels the mill can be adjusted to different application requirements.

Function Principle for Optimum Cutting Effects

Size reduction in the Cutting Mill SM 200 takes place by cutting and shearing forces. The sample comes into contact with the rotor and is comminuted between the blades and the stationary acting cutting bars inserted in the housing.  In the 6-disc rotor spirally arranged reversible plates cut in sequence. The knives of the parallel section rotor 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 and collected in the receptacle. The rotorspeed of 1.500 min-1 ensures gentle and rapid size reduction.  The optional cyclone-suction-combination not only has a cooling effect on the sample but also improves the discharge of material from the grinding chamber.

Operation with Bottom Sieves

The RETSCH SM 200 cutting mill stands out for its precise and efficient size reduction thanks to the bottom sieves. By using a wide range of bottom sieves with different mesh sizes the SM 200 allows to achieve a defined final fineness according to your application. This flexibility is essential for laboratories and industries which need consistent results for many different materials, from soft and medium-hard to tough, elastic and fibrous samples.

In the heart of the SM 200 is a push-fit rotor with double acting cutting bars and reversible hard metal plates. This design ensures optimum cutting effects and heavy metal free grinding, so the instrument is suitable for sensitive applications. The double acting cutting bars work together with the sieves for powerful size reduction and the reversible hard metal plates extend the lifetime of the grinding tools and maintain high performance over time.

Flexibility is a key feature of the mill. The system can be easily adjusted with different hoppers, collecting vessels and sieves for many sample types, including heterogeneous mixes, aluminium slag, non-ferrous metals and refuse derived fuels. So the mill is a universal standard model which covers a wide range of applications in agriculture, recycling, pharmaceuticals and materials science.

Safety is a top priority in the design. Features like central locking device, electronic safety check and engine brake provide robust protection for the user and ensure the instrument meets the highest safety standards during operation. The easy to operate instrument is designed for fast size reduction and fine size control, so it’s a reliable choice for demanding environments.

aluminium slag, animal feed, bones, cables, cardboard, electronic components, feed pellets, foils, food, leather, lignite, material mixtures, non-ferrous metals, paper, pharmaceutical products, plant materials, plastic toys, plastics, polymers, refuse derived fuels, resins, rubber, spices, straw, textiles, waste, wood, ...
