Retsch Ultra Centrifugal Mill ZM 300


Retsch developed the first Ultra Centrifugal Mill ZM 50 years ago. The latest model ZM 300 comprises the essence of German engineering expertise combined with high-quality materials and the latest software technology. The powerful Ultra Centrifugal Mill ZM 300 provides maximum grinding performance at high speed while, at the same time, ensuring operator convenience and safety.

The Ultra Centrifugal Mill ZM 300 is used for the rapid pulverization of soft, medium-hard, brittle, and fibrous materials. Size reduction is effected through impact and shearing forces between a ring sieve and the horizontal rotor. The maximum feed size is 10 mm. Especially with maximum speed, a final fineness of 40 μm (d90) and below may be achieved, depend-ing on the material. This is the maximum achievable fineness amongst all rotor mills in the market. The revolution speed of the ZM 300 ranges from 6,000 to 23,000 min-1, which makes it faster than any other Ultra Centrifugal Mill. Compared to the predecessor model ZM 200 with a maximum speed of 18,000 min-1, it is, on average, 28 % faster. The high speed also has a positive impact on the grinding efficiency and the sample throughput.

Additional advantages of the ZM 300:

  • Maximum speed for high final fineness and increased throughput
  • Increased reproducibility through temperature monitoring via integrated temperature sensor
  • Convenient operation and easy cleaning
  • Suitable for cryogenic grinding of tough sample materials
  • Great versatility thanks to wide range of accessories, The ZM 300 can be equipped with different rotors and ring sieves
