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. Cuttings mills offer a high level of operational safety and convenience. The wide selection of accessories allows for easy adaptation to different application requirements.
*depending on feed material and instrument configuration/settings
Size reduction in cutting mills is effected by cutting and shearing forces.
The sample passes through the hopper into the grinding chamber where it is seized by the rotor and is comminuted between the rotor blades and the stationary cutting bars inserted in the housing.
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.
