High frequency ore screen is also used in fine-grained classification operation for the concentrator grinding and classification process, whose screening efficiency can reach to more than 70% under one condition like that the rational feeding concentration, discharging granularity (-200 Mesh size fraction content), and the demand under the screen size to the difference between feed size less than 30 percent under the conditions.Powder-grinding equipments maily include raymond pulverizer,micro powder mill,bucket elevator and belt conveyor.

The high frequency ore screen produced by Hongxing has obvious advantages of high efficiency, small amplitude, high separated frequency, etc. Its working principle is different from ordinary screening equipments. Because of the high frequency, on the one hand, this equipment can destroy the tension of the mash surface and make the fine material vibrate with a high speed on the screen surface, which can increase the separation effect of the useful mineral 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 material small separation size.

In the grinding circuit, the high frequency ore screen controls the grinding equipment to do the classification. Firstly, screen out of the coarse grain and send them back to the grinding equipment. Then, the fine grain material, or the screening material, will be discharged timely, avoiding the over crushing caused by the regrinding. The width of the screen surface grate seam is different and the particle size of the material is also different. The equipment separates material according to the abovementioned two points.

In addition, the screening material can meet the requirement of fineness, which can improve the mill production, reduce the energy consumption, and increase the benefit. 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 regrind and select the screening material, so as to improve the grade of concentrate.
