Ultra-Centrifugal Mill UCM1100 applies to a wide range of samples. Based on its high efficiency grinding technology and rich accessories, with two-steps grinding of rotating knife – ring screen system, it can process dry and wet grinding in a very short time for the soft, hard, brittle, fibrous samples.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 impacting force to perform pretreatment for samples; then the samples are sheared, extruded and rubbed again between the rotor and ring sieves.
