The high frequency screen can be classified into the following three types according to the different usage and application of the raw material, one is high frequency mineral screen and the other is high frequency ore screen, and today we will introduce some basic information about the two frequency screens. High frequency mineral screen also called mineral high frequency screen is one machine which is used to screen the qualified material from the raw materials at a high speed.
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.
High frequency mineral screen has high efficiency, small amplitude and high screening efficiency and other features, and its principles is different from that of ordinary screening equipment. The high frequency of the high frequency vibrating screen can undermine the tension on the slurry surface and the high-speed oscillation of fine material on the screen surface, speed up the separation effect of useful minerals with big density (specific weight), and increase the contact probability between sieve mesh and materials, resulting in a better separation.
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.
