1, high frequency screen is widely used in mineral processing, coal, chemical industry, brick, food, pharmaceutical, alkali, chemical fertilizer, paper and other industries of all kinds of material of dry and wet screening, grading and dehydration. Used in the grinding classification process of concentrator in fine particle classification work.
2, in the proper feed concentration, feed particle size fraction content (200 meshes), as well as the requirements under the screen size and feed particle size under the condition of less than 30%, the difference between the screening efficiency is as high as above 70%.
3, due to the high screening efficiency, can greatly reduce the cycle load and oversize of qualified grade levels, so as to improve the processing capacity of mill (usually 5 ~ 10%) can be improved.
4, strict screening process for undersize material granularity control, eliminate coarse grain of adverse impacts on the concentrate grade; Other pulp in high frequency under the action of small amplitude oscillations of screen surface, has the effect of density stratified sampling, the high density small particles are easy to fall into through sieve sieve surface, thus can obviously improve the grade of the undersize material. The grade.
