4.Feature and advantages 

image

Provide all kinds of accessories to ensure the application of diversification 

The final fineness less than 100μm 

Speed adjustable from 6000-18000rpm 

Two stage rotor-ring sieve system to realize quickly grinding. 

95mm rotor diameter and 99.43m/s peripheral speed ensure the high efficiency of grinding process. 

Touch control panel, convenient and quick. 

The specifically 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 double anti-blocking hopper can effectively prevent feed stock blocking and reduce noises. 

Special adapters can be equipped to perform large-capacity

The motor is equipped with the function of overload protection, and it can keep running after restarting due to overload.

 

5.Working Principle

image

The Ultra Centrifugal Mill FM200 can realize two-stage crushing for samples with the rotor and ring sieves. Samples are feed 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 preparation 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.
