High Frequency Screen
Compared with the commonly screening and grading equipments, the High-frequency screen adopts higher frequency. As a result, it is able to damage tension force of the pulp surface. Also the fine particles are able to oscillate speedily on the surface of the screen because of the high frequency, and the big expecting minerals are isolated from the pulp easily.
High Frequency Screen Application
High frequency screen is widely used in mineral processing, coal preparation, chemical, brick, food, pharmaceutical, alkali, fertilizer, paper and other industries in a variety of materials in dry, wet screening, grading, dehydration. Concentrator grinding and classification processes for the fine grading operations. At the appropriate concentration of feed, feed particle size (-200 mesh size fraction content), as well as the needs and conditions under the screen next to the size difference between the expected size of less than 30 percent, screening efficiency up to 70%. Due to high efficiency, can significantly reduce the load on the circulation of qualified material and sieve size fraction content, thereby increasing the mill processing capacity (generally increased by 5 to 10 percentage points). Screening process to screen size under strict control things, to eliminate the adverse effects of too coarse grains of ore concentrate grade; another pulp at the screen surface high-frequency small amplitude oscillation effect, there are stratified according to the density of the role of high-density particles tend to settlement to the screen surface and through the screen, it can significantly improve the quality of undersize material.
