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.

This high frequency screen equips nylon or stainless steel sieve which is the necessary equipment for fine iron ore. At present the rich ore reserves are growing poor and poor, we should fully use of the limited mineral resources to create more wealth, using high-frequency vibrating screen, we can improve the fine ore powder 3-5 grade, and bring the good economic benefits and social benefits

1. High efficiency, small amplitude and high screening frequency.2. Since our high frequency screen does not contain rotating parts, there is no need of lubrication.3. Simple structure.4. Convenient to repair with low fault rate.5. Driving power of this machine is small, so with a small starting current and low noise.6. Adjustable of the body, and the size of the product can be controlled.7. Stable value.8. The sieve gap is not easy to block material.

customersHigh frequency screen are widely used in mineral processing, chemical, coal washing and other industrial, for the 0.074-1.5mm fine particles, it applicable for wet classification, dehydration and slag removal, can improve classification Efficiency and control of selected particle size, also improve the concentrate grade. Eat iron ore concentrator can use it deslagging before the strong magnetic machine.

High frequency screen consists of vibration exciter, ore pulp distributor, screen frame, machine frame, suspension springs and sieve, etc. This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.

It differs from the conventional screens with breaking of the surface tension of pulp and high speed vibration on sieve cover and accelerates the separating of large-density useful mines, and it increases the contacting probability of the materials smaller than output granularity and the sieve pore. Therefore, it results into good condition and makes the materials smaller than the output granularity, especially the big-density materials and pulp get through the sieve pore together.

High frequency vibrating mesh screen consists of base, frame, and rubber damping spring, low frequency electromagnetic vibrator, screen box, mesh screen, high frequency electromagnetic vibrator, support, angle adjustment bar and electronic control box. When the machine operates, the low frequency electromagnetic vibrator vibrates the feeder and outputs part of the mesh screen directly to move the whole screen. At the same time, the high frequency electromagnetic vibrator shakes the middle of mesh screen through the rubber cushion. The mesh screen is composed of three stainless steel screen layers; the lowest screen layer is high strength primary screen which is connected with the shake motor; the other two layers are workable screen in mine processing.

High-frequency screens are widely used for screening or grading iron ore, gold ore, copper ore, and silica sand. It is especially suitable for the screening of fine-grained powder materials. The graded particle size is 0.074~1mm; the fineness is up to 300 mesh; the sieve surface vibration frequency is 50Hz; and the amplitude is 0~2mm. The screen area is 4.5-8.1 square meters, and the running power is 0.72. -2.2kw.

Adopting the new principle design, it is a new type of high-efficiency screening machine with a screening efficiency of over 70%, small amplitude, and high screening frequency. Different from the principle of general screening equipment, the high-frequency screen uses high frequency and it can destroy the tension of the slurry surface and the high-speed oscillation of the fine material on the sieve surface, accelerate the separation of large-density useful minerals, and increase the probability of separating the material in a smaller particle size.
