High-frequency Vibrating Screen range is specifically designed and manufactured for the mining industry, building and construction industry. Of course, the final products can also be used into other fields depending on actual demands of our clients. High-frequency screen is high efficient sieve with high intensity vibration excitation, which is combined with international advanced manufacturing technology as well as based on the twenty years' shaker design experience of our company. 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 Working Principle

This series of high-frequency vibrating screen beneficiation machine with eccentric block as the excitation source to drive the sieve box for circular vibrating, its working principle is the screen box through the elastic support on the base (or base), the eccentric block is mounted on the spindle, the spindle through the bearing and the bearing seat is arranged on the side of the screen box. Motor driven by triangle with intermediate shaft, intermediate shaft drives the rotation of the spindle, spindle rotates to drive an eccentric block to rotate, inertia force of the eccentric block to produce forced vibration sieve box. With the motor running, the approximate circular locus motion high-frequency screen, realize continuous screening operation.

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.
