High frequency sieve

Introduction of PC HAMMER crusher

The high frequency sieve (high quality sieve) uses self-synchronous vibration to excite, and under the action of the exciter, theieve machine makes a high frequency reciprocating linear motion, with high screening frequency, small amplitude and high efficiency, which is an effective equipment for sieving and classifying fine particles The high frequency sieve uses high frequency to destroy the surface tension of the pulp and the high speed vibration of fine particles on the sieve surface, which accelerates the density of minerals and the separation effect, and improves the probability of contact between materials smaller than the separation particle size and the sieve holes, creating better separation conditions, so that materials smaller the separation particle size, especially high density materials and pulp, are sieved out through the sieve holes together.

The high frequency sieve is driven by a variable speed frequency converter electromagnetic vibrator, which can obtain different amplitudes by adjusting the counterweight inside the vibrator. can obtain the desired production efficiency by changing the frequency and amplitude.

Under the same output requirement, the working efficiency of the high frequency sieve is 1.5-2 that of the same category of circular vibrating sieve.

Working principle of hammer crusher

High frequency screen is used for the fine particle size operation in the grinding and classification process of the mineral processing plant, and the material is classified according to the of the particles by using the different widths of the screen surface. In the grinding circuit, the grinding product is controlled and classified, and the coarse particle agglomerate is out, that is, the screen is returned to the mill for further grinding. The fine particles, i.e. the screen residue, can be discharged in time to avoid overgrinding caused by further grinding. Timely screening of materials to meet the fineness requirements can improve the output of the mill, reduce energy consumption and increase profits. If the high frequency is installed in the mineral processing circuit, it can screen out the coarse particle concentrate to be sent to the mill for further grinding, and the fine particles can be selected, so it significantly improve the grade of the concentrate.
