The high-frequency screen (high-grade screen) is excited by a self-synchronous vibrator. Under the action of the vibrator, the screen machine performs high-frequency reciprocating linear motion. The screening frequency is high, the amplitude is small, and the efficiency is high. It is a fine-grained material screen. Classified effective equipment. The high-frequency screen uses high frequency to destroy the tension of the pulp surface and the high-speed vibration of fine-grained materials on the screen surface, which accelerates the separation of useful minerals with relatively high density, and increases the probability of contact between materials smaller than the separation particle size and the screen holes, resulting in Better separation conditions, so that materials smaller than the separation particle size, especially high-density materials, are screened out through the sieve holes together with the ore pulp.

Designed with a new principle, it is a screen surface vibrating screening machine with a new structure, generally using nylon or stainless steel screen plates.
The vibration frequency of the screen surface is 50Hz, the amplitude is 0-2 mm, and the vibration intensity is 8-10 times of the acceleration of gravity, which is 2-3 times of the vibration intensity of the general mechanical vibrating screen.
The sieve surface is not easy to block holes, has high sieving efficiency and large processing capacity, and is especially suitable for sieving fine-grained powder materials. The grading size is 0.074~1mm
The whole machine is supported by vibration damping, so that the ground basically does not bear the dynamic load, and it does not need to make a foundation. It can be installed directly on a solid and flat ground, or a common steel structure platform can work normally. The installation angle of the screen machine is convenient and adjustable, and the inclination angle of the screen surface can be adjusted according to the required mineral particle size.
The high-frequency screen is used for the fine-grained operation in the grinding and grading process of the concentrator. The width of the grate gap on the screen surface is different, and the material is classified according to the particle size. In the grinding circuit, the grinding products are controlled and classified, and the coarse-grained conjoined organisms are screened out, that is, the oversize is returned to the mill for regrinding. The fine particles, that is, the undersieve, can be discharged in time to avoid over-crushing caused by regrinding. Timely screening out materials that meet the fineness requirements can increase the output of the mill, reduce energy consumption, and increase profits. Installing a high-frequency screen in the beneficiation circuit can screen out the coarse-grained concentrate and send it to the mill for re-grinding, and the fine particles under the screen can be selected, so the grade of the concentrate can be significantly improved.
