Cutting Mill SM 300
Cutting mills are suitable for the dust-free grinding of elastic, fibrous, and heterogeneous mixes of products. The new Cutting Mill SM 300 excels especially in the tough jobs where other cutting mills fail.
The high torque of the new 3 kW drive with additional flywheel mass allows for an exceptionally effective preliminary size reduction of heterogeneous mixtures, such as waste or electronic components. Analytical fineness is often achieved in one working run.
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. Another innovation is the wide, freely selectable speed range from 700 to 3,000 min-1. 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

Function Principle
Size reduction in the Cutting Mill SM 300 takes place by cutting and shearing forces. The sample comes into contact with the rotor, and is comminuted between the blades and the stationary double acting 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. An additional flywheel mass on the drive shaft produces the exceptional performance of the SM 300. Thanks to the variable speed from 700 to 3,000 min-1, the SM 300 can be easily adapted to different application requirements
