High frequency screen is composed of exciter, pulp distributor, screen frame, rack, hanging spring and screen mesh. High frequency vibration fine screen is called high frequency screen for short and it is a type of classifying machine used in the ore dressing plant. The gap width of the grating of the screen is different, so that it classifies materials according to the material sizes.

High frequency screen has high efficiency, small amplitude and high screening frequency. Different from the working principle of common screening equipment, high frequency screen uses high frequency, which on the one hand breaks the tension of the ore pulp surface, and on the other hand, the fine particles vibrate with high speed on the screen surface, thus accelerating the separation of big density and useful minerals and increasing the probability that the materials smaller than the separation granularity contact the screen hole.

In the return circuit of the ore grinding process, this machine is used for the control and classification of the grinding ore product and screen out the coarse particles and the raw materials on the screen and return them to the grinding mill for re-grinding. The fine particles under the screen can be timely discharged to avoid re-grinding and over crushing. Timely screening the materials that reach the fineness requirement can improve the output of the grinding mill, reduce the energy consumption and improve the economic benefits. Installing a high frequency screen in the dressing return circuit can screen the coarse ore concentrate and send it to the grinding mill for re-grinding, and the fine particles under the screen are concentrated to improve the taste of the ore concentrate.

The high frequency vibrating screen is referred to as a high-frequency screen, which is composed of a vibration exciter, a slurry distributor, a screen frame, a frame, a suspension spring, and a screen. It is widely used in mineral processing, coal preparation, chemistry, brick making, food, pharmaceutics, alkali, fertilizer, paper, and other industries.

3. The side plate of the screen box is formed by integral bending of the steel plate, which not only improves its overall rigidity and working reliability but also makes the shape of the equipment more beautiful.

high frequency screening: from piles to profit - quarry

high frequency screening: from piles to profit - quarry

The underlaying features of high frequency screens have remained constant, that is, their highly efficient ability to separate particles from around 25mm down to 0.425mm and the capability to handle wetter, stickier materials. What has now developed is the means at which this capability is deployed.

Astec has now produced three track-mounted systems, to be used for a variety of applications. The FT2618VM is the system with the most runs on the board, as it typically runs in-line with Astecs FT2650 tracked jaw crusher and FT300 tracked cone crusher as a final screen for producers wanting to screen for a specific manufactured sand profile. Recently, the high frequency range has increased to include the GT205 multi-frequency tracked screen and the GT165 multi-frequency tracked screen.

{{image2-a:r-w:300}}The GT205 is a direct feed screen with a conventional top deck to screen off top size overs but also includes high frequency technology on the second and third decks to allow a more efficient product cut.

Recent use cases have seen the GT205 being fed recycled gypsum, recycled glass and topsoil. The most intriguing use case has been the processing of otherwise waste material to produce low grade road base that meets local council specifications.

Astec has recently launched the GT165. In this configuration, the multi-frequency screen with its mix of conventional screening on top deck and high frequency lower deck has been arranged for scalping. The benefits of using the multi-frequency configuration in the scalping function is that raw feed (larger rock) can be handled on the top side deck, while the second deck can run a much finer screen cloth that can handle a stickier type of materials often found in scalping applications.

Apart from mobile track-mounted applications, Astec has also sold different sized high frequency screens that have been mounted in a modular frame. With minimal dynamic loading, the structures are modest, robust and can be used for a wide variety of applications. The most common use cases for high frequency screens in static applications include operations processing crusher run of dust into manufactured sand.

To accommodate unique site requirements, static applications of high frequency screens can be configured with multiple decks and differing lengths and widths. One of the strengths of running the high frequency screen is the ability to change the screen angle, frequency and stroke of the individual screen decks. This control allows tuning of the screen to the properties and size of the material being screened, giving precise stratification and optimal screening outcomes.

To date the high frequency screen has been successfully used in manufactured sand, concrete stone, agricultural lime, recycled materials and topsoil. To assist producers in scoping the high frequency screen for their application, Astec offers a complimentary material testing service where customers can test their specific materials on a demo screen at the Astec head office in Brisbane, Queensland.

The high-frequency screens manufactured by Midwestern can be utilized in many screening applications from rugged quarry and rock sizing to sand and gravel processing and high volume fine mesh screening. With a variety of sizes and screening decks, the versatile MEV Screener can fit numerous applications.

The MEV High-Frequency Screener is a rectangular screener that utilizes an elliptical motion to convey material across itsscreening surface. Available in sizes three-foot by five-foot (3 x 5), four-foot by eight-foot (4 x 8), and five-foot by ten-foot (5 x 10) with the availability of one to five screening decks gives the MEV Screener the versatility to meet your screening needs.

The MEV Screener is designed to retain material at the feed end for a longer period of time and then gently slops the material near the discharge end, assisting itoff the screening deck and into production. This is achieved by the screeners unique parallel-arc configuration. Crossbars support the end-tensioned screens tocreate a flat screening surface, thus maximizing the screening area.

The end-tensioned screens used in the high-frequency screener simplify changing screen panels. End-tensioning permits the use of square-opening and slotted screens and is accurately maintained by a spring-loaded drawbar. Users can make screen changes in 1015 minutes.

Midwesterns commitment to providing our customers with outstanding screening products continues with our full line of replacement rectangular screens. Our screens are manufactured to fit all makes and models of screeners.

TCI high frequency screens, commonly referred to as "PEP screens", come in a variety of sizes, frequency levels and configurations. Fine material is best separated with high speed and a small stroke. They are available in single or double deck configurations, and are equipped with either electric or hydraulic vibration. The ratchet-type screen tensioning makes for easy screen panel changes.
