The high frequency ore screen refers to the high frequency screen which is one of the classification machines for dressing plant. It is mainly composed of exciter, mash distributor screen frame, bracket, hanging spring, screen mat and other components.
The high frequency ore screen produced by Henan Hongxing Mining Machinery Co., Ltd. has obvious advantages of high efficiency, small amplitude and high screening frequency. Its working principle is different from that of ordinary screening machines. Because of its high frequency, this equipment can destroy the tension of the mash surface and make the fine materials vibrate with a high speed on the screen surface, increase the separation effect of the useful minerals with high density and improve the probability of smaller granularity contacting with sieve pore. Therefore, this kind of high frequency ore screen has a better screening condition which makes the materials in a small separation size, especially for the materials with a high ratio and mesh come across the mesh together.
The screening principle is that the width of the screen surface grate seam is different and the particle size of the material is also different. According the above two points, the equipment separates the materials. In the grinding circuit, the high frequency ore screen controls the grinding equipment to do the classification. First of all, the machine screens out the coarse grain and sends it back to the grinding equipment. Then, the fine grain materials, namely the screening materials, will be discharged in time to avoid over crushing. In addition, the screening material can meet the requirement of fineness, which can improve the mill production, reduce the energy consumption and increase the benefits. What’s more, installing the high frequency ore screen in the grinding circuit can screen out the coarse concentrate and send it back to the grinding mill to do regrinding and select the screening material and improve the grade of the concentrate.
