High Frequency Screen

High frequency screen is also called high frequency vibrating screen, which is a kind of separating equipment in ore dressing plants. It separates materials according to their particle sizes. High frequency screen has high efficiency and small amplitude, which is the effective equipment for the screening and grading of fine materials. It is widely used for screening or grading operations in ore dressing plant, such as iron, tin, tungsten, tantalum, niobium sand, etc. High frequency screen results in better separation conditions, which make the material which is less than the separation granularity, especially the large ratio particles get through the sieve together with the pulp.

The Usage of High Frequency Screen:

High frequency screen is widely used for various dry and wet screening, grading and dehydration of materials in coal industry, chemical industry, food, pharmaceutical, alkali making, chemical fertilizer, paper making and other industries. For the grading of fine particles in the grinding process of ore dressing plant, in the conditions of appropriate feed concentration, feed particle size (-200 mesh size), screen size and particle size of less than 30 percentage points, its screening efficiency is more than 70%.

Because the screening efficiency is high, it can greatly reduce the circulating load and screening qualified particle content, so as to improve the processing capability of the mill (generally can be increased by 5 to 10 percentage points). The screening process has strict control of the particle size, which can eliminate the adverse effect on the grade of concentrate pulp caused by coarse particles; in addition, with the high frequency and small amplitude vibration, the pulp on the screen surface will have density stratification effect. The small particles with high density will tend to subside to the screen surface to get through the sieve, which can obviously improve the grade of screened materials.
