Cutting Mill SM 400 XL

Data sheet


Cutting mills are suitable for the grinding of soft, medium-hard, tough, elastic, fibrous, and heterogeneous mixes of products. The Cutting Mill SM 400 XL is ideally suited for pre-cutting of large sample pieces but, depending on the application,  may also achieve the required fineness in one step.

The high torque of the new 3 kW drive allows for an exceptionally effective preliminary size reduction of heterogeneous mixtures, such as waste or electronic components.

The cutting mill is used successfully for a great variety of materials. The sample is only moderately warmed up during the grinding process so that the mill is perfectly suitable for grinding temperature-sensitive materials.  Due to the large open surface of the 240 mm x 240 mm bottom sieve, it is possible to grind large sample quantities and to increase the throughput.

When operated with the optional cyclone-suction-combination, the SM 400 XL is also suitable for grinding light sample materials. In combination with the wide choice of bottom sieves, hoppers and collecting vessels, the mill can be easily adapted to varying application requirements.

Application Examples

animal feed, bones, cables, cardboard, feed pellets, foils, food, hay, leather, lignite, material mixtures, paper, PET preforms, pharmaceutical products, plant materials, plastic toys, plastics, polymers, refuse derived fuels, resins, rubber, spices, straw, textiles, waste, wood, ... continue to application database

Function Principle

Size reduction in the Cutting Mill SM 400 XL takes place by cutting and shearing forces. The sample hits the rotor and is comminuted between the blades and the stationary cutting bars inserted in the housing.

Thanks to the wide range of accessories, the SM 400 XL can be easily adapted to different application requirements
