Ultrasonic Sieving Machine for High-Precision Fine Powder Screening
Our ultrasonic sieving machine provides an efficient solution for fine powder screening. By applying ultrasonic vibration, it helps prevent mesh clogging and improves screening accuracy for powders that are difficult to separate. It is suitable for pharmaceutical, food, chemical, and other industrial applications.
What Is an Ultrasonic Sieving Machine?
The ultrasonic sieving machine is developed by upgrading the traditional three-dimensional rotary vibrating sieve. It features a redesigned screen frame structure and an integrated ultrasonic screening system.
With the combined action of the vibration motor and ultrasonic system, the screen surface generates high-frequency, low-amplitude ultrasonic vibration. This keeps the material suspended on the screen surface, reducing problems such as sticking, friction, material blockage, and mesh clogging.
The ultrasonic sieving machine effectively solves common screening challenges of fine and difficult-to-screen materials, including mesh blocking, material adhesion, electrostatic attraction, agglomeration, and low-density material screening. For repeated mesh blockage, learn more about the causes of fine powder screen blinding and how to prevent it.
Принцип работы
1. Conversion of electrical power (220V/50Hz or 110V/60Hz) into 38kHz high-frequency electrical energy via the ultrasonic generator, resulting in high-frequency, high-voltage alternating current.
2. Conversion of electrical energy to mechanical energy: High-frequency power is delivered to the transducer, causing the internal piezoelectric ceramics to rapidly expand and contract upon energization, thereby generating ultra-high-frequency micro-vibrations at a rate of 300,000 to 400,000 cycles per minute.
3. Vibration transmission: Vibrations from the transducer are transferred to the resonance ring and then distributed evenly across the entire stainless steel screen mesh.
4. Continuous high-frequency micro-vibration of the screen mesh breaks up agglomerated fine powders and overcomes electrostatic adhesion; particles do not stick to the mesh or clog the apertures, allowing fine material to pass through rapidly while coarse material is smoothly discharged.
Why Choose an Ultrasonic Sieving Machine for Fine Powder Screening?
An ultrasonic sieving machine is designed to improve the screening performance of fine and difficult-to-screen powders. By using ultrasonic vibration technology, it can reduce mesh clogging, improve screening accuracy, and maintain material quality during the screening process. Compared to vibrating screens without ultrasonic devices, the mesh passage rate increases by 5 to 20 times.
Prevent Screen Mesh Blocking During Fine Powder Screening
Fine powders often cause problems such as mesh blocking, powder sticking, and electrostatic adhesion during screening. The ultrasonic sieving machine creates high-frequency vibration on the screen surface, which helps prevent particles from sticking to the mesh. This allows materials to pass through the screen smoothly and reduces cleaning time and production downtime.
Improve Screening Accuracy for Ultra-Fine Powders
For ultra-fine powders and micron materials, traditional vibrating screens may have difficulty maintaining stable screening performance. The ultrasonic sieving machine provides a more precise screening process for materials with high mesh requirements, including 100-625 mesh powders. It is widely used for pharmaceutical powder screening, chemical powder separation, and other fine powder applications.
Maintain Material Quality During Screening
Эта ultrasonic sieving machine uses low-amplitude ultrasonic vibration to gently separate materials without damaging their original properties. This helps protect sensitive materials, reduce particle breakage, and maintain consistent product quality during the screening process.
Contamination Prevention
Battery materials (such as graphite powder, polysilicon, and precursors) are extremely sensitive to metallic impurities; contact with metals like copper or zinc can trigger oxidation reactions, contaminating the material and degrading battery performance. Ultrasonic vibrating sieves feature a Teflon coating applied to the screen frame and bottom cover, creating a physical barrier that prevents direct contact between the material and steel components, thereby ensuring material purity.

How to Select the Right Ultrasonic Sieving Machine?
Choosing the right ultrasonic sieving machine depends on your material characteristics, production capacity, and screening requirements. A suitable machine can improve screening efficiency, reduce mesh clogging, and achieve stable powder separation performance.
1.Material Characteristics
Fineness
Traditional screening is an option for 100 mesh or coarser; ultrasonic screening is preferred for finer than 100 mesh.
Viscosity / Static Electricity
Ultrasonic anti-clogging technology is required for highly viscous materials (e.g., adhesives) and materials prone to moisture absorption.
2.Capacity Requirements
Select the equipment diameter (e.g., Model 800 or 1200) based on the hourly processing volume (tons/hour).
3.Material Requirements
Choose 304 or 316 stainless steel for food and pharmaceutical applications; for corrosive chemical environments, select materials with acid- and alkali-resistant coatings.
