Ultrasonic Frequency Variation for sieving is significantly shortened

HAVER UFA Ultrasonic Frequency Variation for Test Sieves

The HAVER UFA is especially designed for the sieving of powders at critical particle size cuts of ≤ 300 micron. The screen is excited by means of ultrasonic wave at continuously varying frequency. The tendency to block is reduced, the performance of the sieve is increased and the time required for sieving is significantly shortened.
