For successful sieving of fine powders with critical separation cuts of ≤ 300 µm NEXOPART offers you the ultrasonic frequency variation for test sieves. An important tool for you if you want to analyze your fine bulk material using a vibrating sieve shaker.  With a few simple steps you can excite the sieve mesh with a continuously varying ultrasonic frequency
 
  1. step: Tighten the clamping ring around your NEXOPART test sieve.

The high-frequency vibrations that are generated reduce the frictional resistance between particles and sieve mesh. Your result:
 
  • minimized clogging tendency,
  • destruction of agglomerates,
  • higher screening capacity and a shortened screening time,
  • low mechanical load on the screen bottom + side effect cleaning of the screen mesh,
  • Parallel handling of several test sieves with only one generator (enables connection with two converters, twin operation)
For some bulk materials, sieving with vibration sieving machines becomes possible for the first time.

Analog or digital ultrasonic frequency variation.


As a "plug-and-play" solution, you can attach the NEXOPART UFA in an analog or digital version conveniently, quickly and safely to all standard test sieves. The digital device allows you to excite several test sieves simultaneously with only one generator. With the help of the twin unit, it is even possible to connect two converters.
