1. Summary of the high frequency ore screen
The high frequency ore screen refers to the high frequency screen, which is one of the classification equipments for dressing plant. It is mainly composed of the exciter, mash distributor screen frame, bracket, hanging spring, screen mat and other components.
2. Performance Characteristic of the high frequency ore screen
The high frequency ore screen produced by Henan Hongxing Mining Machinery Co., Ltd. has obvious advantages of high efficiency, small amplitude, and high separated frequency. Its working principle is different from ordinary screening equipments. Because of the high frequency, this equipment can destroy the tension of the mash surface and make the fine material 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 material with a high ratio and mash come across the mesh together.
3. Working principle of the high frequency ore screen
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 above two points, the equipment separates the material. In the grinding circuit, the high frequency ore screen controls the grinding equipment to do the classification. First of all, the machine screens out of the coarse grain and sends it back to the grinding equipment. Then, the fine grain material, namely the screening material, will be discharged in time to avoid the 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 them back to the grinding mill to do regrinding and select the screening material, and improve the grade of concentrate.
