Ultrasonic Powder Sieve Machine

MAR series ultrasonic powder sieve system is a professional ultrasonic screening system, which is composed of ultrasonic generator and screen transducer. It can meet the use range of 28 ~ 38kHz frequency. The system can automatically track the best resonant frequency and compensate for the detuning caused by heating and other reasons; It can also be added to any new or existing vibrating screen;

The amplitude range of Mar series ultrasonic screening system is continuously adjustable from 20% to 100%, which is different from the shortcomings of traditional generators that are difficult to work with low amplitude. It can remove the easily agglomerated and viscous powder from the screen surface, increase the screening capacity, improve the powder screening efficiency, and reduce the screening mesh to 20 microns (635 mesh);

The whole Ultrasonic Powder Sieve Machine can not only greatly improve the quality of powder products, make the screening particle size more accurate and efficient, but also reduce the screen loss and the time of repair and replacement, which is conducive to good cost control. The main application fields are classification, protective screening, dust removal and typical analytical screening in the laboratory.

FAQ：

Q：What are the factors that affect the screening accuracy of Ultrasonic Powder Sieve Machine?

1, Screen opening rate

Problem: The large opening rate of the ultrasonic vibrating screen mesh affects the screening efficiency of the ultrasonic vibrating screen. The smaller the number of mesh holes per unit area, the larger the mesh holes, and the higher the screening yield. However, it is important to pay attention to the screening accuracy.

Suggestion: When selecting the mesh of the ultrasonic vibrating screen, the selection of the mesh shape should also be similar to the shape of the material particles being screened. For example, for irregularly shaped materials, circular mesh should be selected, while for cylindrical materials, rectangular or circular mesh should be selected. In short, mesh holes with the same size as the material particles cannot be selected.

2, Amplitude and frequency

Problem: The amplitude and frequency of the ultrasonic vibrating screen need to be selected based on the characteristics and particle size of the material. Within a certain range, the amplitude of the ultrasonic vibrating screen can be moderately increased, the frequency of the ultrasonic vibrating screen can be increased, the material layering speed can be accelerated, and thus the screening efficiency of the ultrasonic vibrating screen can be improved.

Suggestion: For larger particle sizes of materials, choose larger amplitudes and lower frequencies, while for smaller particle sizes, choose smaller amplitudes and higher frequencies.

3, Motor power

Problem: The ultrasonic vibrating screen motor, as the source of excitation force, directly affects the strength of the excitation force and also affects the screening efficiency of the ultrasonic vibrating screen.

Suggestion: If you want to increase the screening output, you can appropriately increase the motor power, but remember that the model of the ultrasonic vibrating screen is consistent with the motor power. Simply increasing the excitation force will reduce the service life of the ultrasonic vibrating screen, so please adjust it reasonably when using.

4, Uneven feeding

Problem: When a large amount of material is piled up on the surface of the ultrasonic vibrating screen, the movement speed of the material on the screen surface will slow down, and it will not be fully screened, resulting in uneven material screening and affecting the screening efficiency of the ultrasonic vibrating screen.

Suggestion: The feeding method of the ultrasonic vibrating screen should be uniform and ensure a suitable material layer thickness. A buffer device can also be installed at the feed inlet.

5, Material properties

Problem: The nature of the material is the main factor affecting the screening efficiency of the ultrasonic vibrating screen. Generally speaking, materials with high humidity are prone to adhesion and agglomeration, which may cause blockage of the ultrasonic vibrating screen mesh. Materials with low loose density are not easy to pass through the screen, and the screening effect of the ultrasonic vibrating screen is also slightly poor. The shape of the material particles also affects the screening efficiency of the ultrasonic vibrating screen. Materials with spherical and cubic shapes are more likely to pass through the screen, while those with sheet shapes are more likely to get stuck in the sieve holes, resulting in a decrease in the screening efficiency of the ultrasonic vibrating screen.

Suggestion: When the moisture content of the screened material is high, an ultrasonic vibrating screen with larger mesh size can be selected for screening. For materials with small loose density, secondary crushing can be carried out if necessary before continuing screening.

The above are the reasons and solutions that affect the screening accuracy of ultrasonic vibration screens. As a fine vibration screening equipment, ultrasonic vibration screens can be applied in many fields. When choosing, it is necessary to make reasonable choices based on one's own production process.
