High frequency Screen  Short Introduction

Working principle

The high frequency screen using high frequency can damage the pulp surface tension andfine material in the sieve surface high speed oscillation, accelerated the useful minerals and the analysis of relatively large density from the action, to increase the probability of less thansize separation material and sieve contact, resulting in better separation conditions, so as to make separation less than the granularity material, especially high density materials and pulptogether through a sieve.

The application of high frequency screen

The high frequency screen is widely applicable to all kinds of materials, mineral processing,coal preparation, chemical, food, pharmaceutical, brick, alkali, chemical fertilizer, paper and other industries in the dry, wet sieving, grading, dehydration. For grinding in concentrator offine grading homework ore grading process, in the

Appropriate feed concentration, feed particle size (-200 mesh sieve, content) and the demandunder the particle size and particle size of less than 30 percentage points of the conditions,high screening efficiency reaches above 70%. Because of the screening efficiency is high,can greatly reduce circulating load and screening qualified particle content on fabric, thus improving the handling capacity of the mill (generally can be increased by 5 to 10 percentage points). The screening process on the screen under the strict control of the grain size,eliminate the coarse ore grain of adverse effect on the grade of concentrate pulp; also in the sieve surface under the action of high frequency and small amplitude oscillation, according todensity stratification effect, high density of small particles tend to drop to the screen surfaceand through the screen, so it can significantly improve the undersize grade

The high frequency screen performance characteristics

1, screening new principle design using machine, is a new structure of the high-efficient sievesurface vibration screening machinery, the general use of nylon or stainless steel plate.

2, vibrator driven by the transmission mechanism for high frequency vibration sieve screen surface, static tank. Vibration system design in the near resonance condition, the machinethrough the damping supporting, make the ground does not bear the dynamic load, sievemachine does not need to make a solid foundation, directly installed on flat ground orordinary steel structure platform can work normally.

3, the screen surface vibration frequency of 50Hz, amplitude of 0~2 mm, the vibration intensity is the acceleration of gravity is 8 ~ 10 times, is 2 ~ 3 times of vibration intensity general mechanical vibration sieve. The sieve surface is not easy to plug the hole, high screening efficiency, large handling capacity. Especially suitable for fine powder material screening. Classification size 0.074 ~ 1mm.

4, flexible screen screen surface is composed of three distinct layers. The bottom layer of steel wire rope core polyurethane network support network, laying the wire diameter and the mesh is not the same double stainless steel wire woven composite network. Composite layerfor online network, direct contact with the material for screening work, complex network for the lower bottom net, used to disperse the stress and vibration transmission, to ensure that the working network high screening efficiency and prolong the service life. Screen ends withhook, easy handling and adjust the tension of the screen. Feeding buffer sieve to make pulp dispersion are cloth, avoid direct impact screen damage.
