Due to the high screening efficiency of the high-frequency screen, it can greatly reduce the circulation load and the qualified particle size content in the screened material, thereby improving the processing capacity of the mill (generally, it can be increased by 5 to 10 percentage points).
The screening process strictly controls the particle size of the underscreen, eliminating the adverse effects of over-coarse ore particles on the concentrate grade; in addition, under the high-frequency and small-amplitude vibration of the screen surface, the ore pulp has the effect of layering according to density, and high-density small particles are easy to Settling to the sieve surface and passing through the sieve, so the grade of the undersieve can be significantly improved.
High-frequency screen is an effective equipment for screening and grading fine-grained materials, and is widely used in screening or grading operations in iron ore, tin, tungsten, tantalum, niobium sand and other concentrators.
It is used for the fine particle classification operation in the grinding and classification process of the concentrator, when the appropriate feed concentration, feed particle size (-200 mesh particle size content), and the difference between the particle size under the required sieve and the feed particle size is less than 30 percentage points Under these conditions, the screening efficiency is as high as 70%.
