A generator produces high-frequency electrical signals. These signals are converted into ultrasonic vibrations by a piezoelectric transducer attached to the sieve frame. The vibrations are transmitted directly to the sieve mesh, keeping it free from particle blockages. This enables continuous sieving with higher throughput and finer precision.

Retrofit Design – Can be installed on new or existing sieve machines. Mesh Anti-Clogging Technology – Prevents screen blinding and improves throughput. Wide Frequency Range – Typically operates at 36 – 40 kHz ultrasonic frequency Compatible with Fine Meshes – Works efficiently with meshes up to 20 microns Digital Generator Control – Stable output with adjustable power settings. Energy Efficient – Optimized ultrasonic power consumption. Durable Build – Long-lasting stainless steel and robust transducer assembly. Safe for Sensitive Materials – Gentle ultrasonic action avoids damage to fragile powders.

Higher Sieving Efficiency – Up to 200% improvement in throughput for fine powders. Prevents Mesh Blinding – Keeps sieve mesh clear for longer operation cycles. Improved Accuracy – Enables sieving down to very fine particle sizes. Reduces Product Loss – Ensures clean separation and maximum material recovery. Low Maintenance – Longer screen life due to reduced mechanical stress. Versatile Applications – Suitable for dry powders, wet materials, and difficult-to-sieve substances. Easy Integration – Compatible with most vibrating sieve brands and designs.
