| The grinding art for special samples |
○ Plastic and rubber samples will become brittle and easy to grind in liquid nitrogen condition.
○ The distance ring sieve and automatic vibratory feeder can be used for grinding heat-sensitive samples such as paint, resin.
○ The rotor and ring sieve with wear-resisting coatings can be used for grinding rigid and corrosive materials such as fertilizers,chemicals.
| 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 guaran-tees moderate and efficient grinding results. Due to the high crushing efficiency, the perod of samples staying in the grinding chamber is quite short so as to avoid changes of sample natures.

| Technical highlights |
○ The specially designed air passage can guarantee that the grinding chamber has constant airflow to cool rotors and samples.
○ Real display of temperature in grinding chamber on control screen.
○ 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 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 FM300 can be equipped with an automatic feed device , which can guarantee highly homogeneous grinding results and avoid the risk of sample feed overoad.
○ The ground samples are collected in a collecting pan, which is convenient for collection without sample loss and prevents cross contamination of samples.
○ When using a cyclone or a filter bag, the ground samples can be cooled via airflow and leave the grinding chamber quickly via the collecting pan with an exit, if a vacuum cleaner is connected, the process can be faster and more efficient, The cyclone can be used in coniunction with 250ml or 500ml sample bottles; for large volume samples, the cyclone with the capacity of 3L or 5L can be selected.All parts contacting samples can be removed manually without any tools, and it is quite convenient to clean and install such parts.

Spups
There are 3 kinds of rotors for choice, 24 teeth, 12 teeth and 6 teeth. The 24 teeth is for the crushing of fine sample, while the 12 teeth for general sample and the 6 teeth for coarse massive sample.
Ring sieves
Final fineness depends on the different aperture ring sieve. We also provide the reinforcing screen to enhance the stability of the ring sieve.
○ The material of all the rotors and the ring sieves not only has stainless steel but also the heavy-metal-free for choice to meet different laboratory requirements.
○ The rotor and the ring sieve are chosen according to the properties of the samples, the required final fineness and subsequent analysis.
○ We offer a special ring sieve with shear function, for most materials, about 80% of the samples can reach the fineness of less than the half aperture size of the sieve used.
