Ultra Centrifugal Mill FM200 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.

○  Sample type：
Soft, elastic, fibrous, water-bearing, oily, fatty, dry sample

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.

Features and advantages

○  The final fineness less than 40μm.
○  Touch control panel, convenient and quick
○  Low noise, reliable operation, easy cleaning.
○  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.

Technical highlights

○  The specially designed air passage can guarantee that the grinding chamber has constant airflow to cool rotors and samples.
○  There is a double layer wear proof seal ring between the grinding chamber and the driving motor to prevent dust from entering the motor.
○  The electronic lock and the mechanical lock form double protection for operators.
○  The anti-splashing hopper can effectively prevent feedstock blocking and reduce noises.
○  Special adapters can be equipped for large-capacity collections.
○ The motor has the function of overload protection, and it continues to run after restarting due to overload.

Automatic feed device and large sample receiver

○  Ultra Centrifugal Mill FM200 can be equipped with an automatic feed device , which can guarantee highly homogeneous grinding results and avoid the risk of sample feed overload.
○  The ground samples are collected in a collecting pan, which is convenient for collection without sample loss and prevents cross contamination of samples.
