High Frequency Screen

High frequency vibrating ore 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. This machine works in a re-circulating network with ball mill, which can upgrade the fineness of ferrous and nonferrous metals. Its efficiency is twice that of spiral classifier. It adopts the high frequency and low amplitude vibration for the processing of powder in coal, metallurgy, electricity, construction and chemical industry.

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. 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.
