Ultra Centrifugal Mill FM200 applies to a wide range of samples. Based on its high efficiency grinding technology and rich accessories, with secondary grinding of rotating knife – ring screen system ,it can process dry grinding and frozen ground in a very short time for the soft, hard, brittle, fibrous samples.
 
Work Principle
The fast mill can realize two-stage crushing for samples with the rotor and ring sieves. Samples are fed from the hopper with anti-splashing design. Under the effect of high speed centrifugal force, the falling samples and the high speed rotor generate a giant impact force to perform pretreatment for samples; then the samples are sheared, extruded and rubbed again between the rotor and ring sieves. The samples sizes less than the aperture of ring sieves enter into the collecting pan . The two-stage crushing can form moderate and efficient crushing results. Due to the high crushing efficiency, the period of samples staying in the grinding chamber is quite short so as to avoid changes of sample natures.
