Working Principle
The Ultra Centrifugal 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 sample will enter into the collecting pan when the size is less than the aperture of ring sieves. The two-stage crushing guarantees moderate and efficient grinding 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.

○ Rich accessories for choice ensure the application of diversification.
○ The fineness depends on the ring sieve.
○ Speed adjustable from 6000-18000rpm.
○ Two stage rotor— ring sieve system to realize quickly grinding.
○ Rotor diameter 95mm and peripheral speed up to 94.2 m/s ensure efficient grinding.
