High Frequency Screen

product description:

 
     Frequency screen (high-grade screen) high efficiency, small amplitude and high frequency of screening. And general principles of screening equipment is different, because the high frequency screen (high-grade screen) using high frequency, on the one hand destroyed the pulp surface tension and fine materials, high-speed oscillation screen surface, accelerating the large density (specific gravity) useful minerals and analysis from the role, increasing the probability of a particle size less than the separation of materials in contact with the mesh. Resulting in better separation conditions, so that the separation is less than the size of the material, especially material than the major grain and pulp together into the sieve under the product through the sieve.

working principle:

 
     Concentrator grinding and classification processes for the fine grading operations at the appropriate concentration of feed, feed size (-200 mesh size fraction content), and the need to sieve particle size and particle size difference between the materials is less than 30 percent under the conditions, the screening efficiency up to 70%. Due to high efficiency, can significantly reduce the cycle load and sieve size fractions were qualified in the content, thereby increasing mill processing capacity (generally increased by 5 to 10 percentage points). Under strict screening process to screen size was controlled to eliminate the adverse effects of too coarse ore concentrate grade of grain; additional pulp in the screen surface high-frequency small amplitude oscillation effect, according to the density stratification has the role of a high density of small particles tend to settlement to the screen surface and transparent screen, thus significantly improve the quality of the material under the sieve.

Features:

 
     1, the screening machine with a new design principle, efficient screen surface vibration screening machinery a new structure, generally use nylon or stainless steel sieve.
     2 exciter driven through a transmission mechanism for high-frequency vibration sieve, sieve box stationary. Vibration system design near-resonant mode of operation, the machine is supported through vibration, so that the ground does not bear the basic dynamic load screen machines do not need the system to do basic, direct mounting or ordinary steel platform to work on a solid flat surface.
     3 screen surface vibration frequency of 50Hz, the amplitude of 0-2 mm, the vibration strength of 8 to 10 times the acceleration of gravity, is 2 to 3 times the normal mechanical shaker vibration strength. Screen surface is not easy to clogging, high efficiency, large capacity. Especially suitable for screening fine powder material. Size grading 0.074 ~ 1mm.
     4, the screen surface consists of three layers of different flexible screen composition. The underlying steel cord polyurethane network as the support network, laying on top of the mesh wire diameter and neither the same double stainless steel wire woven composite web. Online Job Board composite layer, in direct contact with the material for screening work, as the lower end of net composite network, for dispersing forces and transmit vibrations to ensure high screening efficiency of the work sites and extend the service life. With hooks at both ends of the screen for easy handling and adjustment of the tension of the screen. Feeding buffer sieve causes the pulp dispersion uniform, a screen to avoid direct impact damage.
