Introduction
High frequency vibrating 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. This creates a good separation environment in which the materials smaller than the separation granularity and especially the materials and pulp with big proportion all can go through the screen holes.

Structure and Working Principle

High frequency vibrating screen is composed of exciter, pulp distributor, screen frame, rack, hanging spring and screen mesh and so on.High frequency screen is short name of high frequency vibration fine screen 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. In the return circuit of the ore grinding process, this machine is used for controlling and grading the grinding ore product,  screening 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.
