First, the working principle of the high-frequency high-frequency screen sieve surface tension and adhesion of the particles to damage by high-frequency vibration between the slurry can be reduced agglomeration force between the fine material, the loose material to achieve fast, hierarchical, increasing the fine Reap the opportunity through the sieve. And by high-frequency vibration can increase the contact material with the screen surface, reduce the clogging of the sieve, to increase the probability of penetration sieve. High frequency screen works as follows: the pulp evenly through the feeder to the sieve of curved segments through continuous shear and vibration of the curved screen, in addition to some fine sieve and water. Entering the straight section engaging portion, the solid-liquid mixture velocity decreased, causes the pulp aggregates, and thus form a "pool", in the high-frequency vibration of the screen surface, the slurry of solid particles drop quickly, due to the contact surface of the screen continue through fine sieve, and gradually form a coarse surface of a thin barrier fine filter layer, but the micro-fine filter layer and moisture can still penetrate through the sieve filter layer, in order to achieve solid-liquid separation. Set by the discharge end of the weir plate blocking material, make the material thicker layer of material on the screen, and further through high frequency, high-intensity exercise throwing water removal. Second, the high frequency characteristics of the current screen, high frequency screen in domestic concentrator has been applied, and achieved good results. Through the practice of producing concluded: high frequency vibrating screen is not only a significant effect of graded dehydration, and played off the mud down the effect of the ash can to a certain extent. High frequency screen features are as follows: 1, vibration parameters: high frequency mechanical vibration sieve general vibration frequency 24Hz, vibration intensity of 5 ~ 7g, amplitude of 2 ~ 3mm: high frequency screen vibration frequency of 50Hz, vibration intensity of 8 ~ 10g amplitude of 2 ~ 3mm. 2. Reliability: high frequency screen does not move because of the screen box, screen vibration, less moving parts, the whole long life and screen life. 3, a small device footprint, high frequency screen in the height direction of small size, compact structure. 4, the initial investment and ongoing maintenance costs, high frequency screen basic body does not move, mainly in vibration sieve, so the plant, the foundation strict, small initial investment. High frequency screen is simple to use, less moving parts, low maintenance, the amplitude is also available online stepless, in daily use on the screen to require periodic replacement. Third, the impact of factors affecting the screening effect of an upper sieve sieve product moisture product moisture is generally between 23% to 26% feed concentration and particle size on the larger screening product moisture and normal feed concentration should between 40% to 50%. Feed concentration is too low will not be formed when the value of the screen surface material layer, the screen will cause the water is high, lower recoveries. High frequency screen screening process must ensure a reasonable feed concentration. 2, feed particle size on the screen, the higher the proportion of coarse particle size, the lower the water screen on the product, the higher the contrary. Because the length of the mounting angle of the screen surface of the screen surface of the water is also a great influence on the material, so the selection and installation of high frequency screen to choose the appropriate installation angle and the length of the screen surface. Hongxing machine is a professional manufacturer of mineral production, good quality circular vibrating screen, high-frequency screen, magnetic separation, flotation machine equipment, long life, welcome you need to consult.
