Pharmaceuticals
** Ensures accurate particle size distribution for active ingredients and excipients.
Use ultrasonic vibration to help sieve fine powders.
How it works
- 01
A generator produces high-frequency electrical signals.
- 02
These signals are converted into ultrasonic vibrations by a piezoelectric transducer attached to the sieve frame.
- 03
The vibrations are transmitted directly to the sieve mesh, keeping it free from particle blockages.
- 04
This enables continuous sieving with higher throughput and finer precision.
Industry applications
An Ultrasonic Sieving Attachment is an advanced add-on device designed to enhance the performance of vibratory sieves and screening machines. By applying high-frequency ultrasonic vibrations to the sieve mesh, this attachment prevents mesh clogging, agglomeration, and blinding, ensuring finer and more accurate separation of powders.
