The New Clamping  Ring - Lock  with screw knob

The HAVER UFA is especially desi-gned for the sieving of powders atcritical particles-size cuts of 300 <00B5>m.

The screen is excited by means of ultrasonic wave at continuously varying frequency.

These high-frequency vibrations reduce the frictional resistance bet-ween particles and the screen:

The tendency to block is reduced, the perfomrance of the sieve is increased

and the time required for sieving is significantly shortened.

This way of aiding the sieving process makes it possible to reach the end of the sieving process much more quickly.

Only using this method makes automated screening possible at all for some bulk materials.
