Ultrasonic Sieve Machines for Fine Powder Screening

In modern industrial processing, handling micron-level fine powders often leads to serious issues such as mesh clogging, agglomeration, and electrostatic adhesion. Traditional vibrating screens are often inefficient when processing materials finer than 200 mesh.

Sanyuantang has developed an advanced ultrasonic sieve machine (ultrasonic vibrating screen) that introduces high-frequency, low-amplitude ultrasonic vibration as an efficient fine powder screening solution, effectively solving these industry challenges.

What Is an Ultrasonic Sieve?

An ultrasonic sieve, also known as an ultrasonic screening machine, is an advanced screening device built on the basis of a conventional rotary vibrating screen, combined with a high-frequency ultrasonic mesh cleaning system.

It converts electrical energy (220V/50Hz or 110V/60Hz) into high-frequency energy (36–38 kHz). Through an ultrasonic transducer, this energy is transformed into mechanical vibration, generating micro-amplitude ultrasonic waves on the screen surface.

This technology effectively eliminates mesh clogging (mesh blinding) and keeps materials suspended on the screen surface, significantly improving high precision sieving efficiency and throughput.

Sanyuantang Ultrasonic Sieve: Advantages in Fine Powder Screening

Eliminates Mesh Blinding and Mesh Clogging Issues

Designed for materials with high adsorption, strong static electricity, easy agglomeration, or low density, the ultrasonic system ensures that the mesh remains continuously open.

Its self-cleaning function eliminates the need for bouncing balls, avoiding secondary contamination of materials.

Improves High Precision Sieving Accuracy and Capacity

Compared with conventional vibrating screens:

• Screening accuracy can be improved by 1–100% 
• Processing capacity can increase by 0.5 to 10 times 

It performs especially well when processing silicon carbide, alloy powders, pigments, and pharmaceutical intermediates.

Protects Material Properties

The smoother screening process reduces material residence time on the mesh surface, effectively preventing heat-sensitive materials from degradation due to friction.

Intelligent Control System

Sanyuantang adopts a new-generation ultrasonic controller with automatic frequency tracking. It adjusts output power based on load conditions, ensuring stable performance during 24/7 continuous operation.
