high frequency vibrating screen with hydraulic pump drive

High frequency vibrating screen has the characteristics of high frequency, strong amplitude, fast processing, widely used in working conditions with strict requirements on screening particle size, and it has important application value in the fields of construction aggregate, mining selection, chemical materials and so on.

The structural characteristics of high frequency vibrating screen:

1. Hydraulic drive system: high-frequency vibrating screen adopts hydraulic vibration pump as the driving source, with a wide frequency range (0-4200 rpm), and the flexible adjustment of vibration frequency can be realized by adjusting the flow of the hydraulic system.
2. Accurate grading: the screening principle is scientific, the coarse material is thrown up due to intense vibration, while the fine material moves close to the screen surface, so as to get more screening opportunities and improve the passing rate.
3. Beat vibration beam design: the core vibration is completed by the beat structure, which can realize higher instantaneous acceleration and impact frequency, and effectively reduce the problem of screen hole clogging.
4. Tensioned screen structure: the screen is tensioned and fixed, with even tension, easy to replace, short maintenance cycle and high screening stability.
5. Compact structure: the whole machine has a compact structure, small footprint, suitable for mobile crushing plant, modular production line or compact layout site.

Advantages of high frequency vibrating screen:

1. Efficient dry screening: no need to add water, adapt to water scarcity areas, to solve the wet screening can not be realized application scenarios.
2. Low energy consumption, flexible adjustment: the hydraulic system output is smooth and fast response, which not only ensures the efficiency, but also saves energy.
3. High-frequency and high-intensity vibration: adjustable high-frequency vibration to ensure that the fine materials quickly through the screen, suitable for fine screening below 5mm particle size.
4. Low rate of screen plugging: frequent vibration of the screen surface and the bouncing effect significantly reduces the material adhesion and the chances of screen hole plugging.
5. Strong application versatility: can be configured in different specifications of the screen (polyurethane, stainless steel, etc.), to adapt to different material characteristics.

The working principle of high frequency vibrating screen:

Through the hydraulic pump drive the flapping vibration beam installed on the screen body, forming high frequency vibration. After the material enters from the feeding end, the vibration prompts the coarse particles to be suspended and thrown up, and the fine particles are close to the screen surface due to their own quality, and frequently get the opportunity to be screened. Compared with ordinary low-frequency screen, high-frequency screen surface vibration more times, in the unit time to complete more classification operations. The tapping method of excitation not only improves the amplitude, but also clears the screen holes to a certain extent, improving the screening efficiency and screen surface utilization.

Application areas of high frequency vibrating screen:

1. Artificial mechanism sand industry: fine sand dry classification, stone powder separation.
2. Mining processing: pre-screening or fine screening of fine materials in the ore dressing process.
3. Coal industry: dry screening of coal powder, pre-screening treatment of de-mediation screening.
4. Metallurgy and building materials: limestone, talcum powder, quartz sand and other powdery materials screening.
5. Chemical materials: calcium carbonate, silica micropowder, ceramic raw materials particle size classification control.
