High frequency electromagnetic vibrating screen

High frequency eleciromagnelic vibrating screen is a new type of screen vibrating screening machine. The high frequency electromaanelic vibration screen directly vibrates the screen surface through the vibration system, but the screen frame does not move, and the vibraion system is in resonance state. The screen machine has the characteristics of low power consumplion, no dynamic load and easy maintenance. The screen amplitude is controlled by several groups of vibration systems, which can be adiusted in seclions at any time. The screen is composed of a composite screen and a supporting screen which are tensioned separately, with strong self-cleaning ability and convenient replacement.

Working principle

This machine is widely used in iron ore, coal washing, chemical industry and other departments. It is used for wet separation of 6-0 mm strong magnetic minerals.

The minerals are divided into two products: magnetic and non-magnetic. This machine is mainly used for the dewatering of th materials under the screen in the iron ore mill. The dewatering effect is remarkable. It can increase the conceniration of the second mill reduce the buoyancy of the second mill, increase the fineness, increase the output, prevent the backfiow of the second mill, greatly improve the working environment, and also be used for the dewatering in front of the filter to make its filter cake better.

Features

1. Adjust the amplitude of the exciter in sections, generally 1-2mm.

2. High vibration frequency, up to 3000 times per minute.

3. The vibration intensity of screen surface is large, up to 9 times of the acceleration of gravity, 3 times of that of general screen machine.

4. Low energy consumption, the power of each group of electromagnetic exciter is 0.35kw.

5. The screen is made of stainless steel wire, which is soft and easy to change.

6. High screening efficiency, not easy to block screen holes, and large processing capacity.

Technical characteristics

1. The computer control box adopts many advanced technologies, such as large-scale integrated circuit single chip, bidirectional silicon controlled and maintenance free. It is controlled by single chip microcomputer and muli-channel silicon controlled at the same time. The design scheme of low energy consumption is adopted. The computer control box achieves quasi zero power consumption, so that the whole electrical property can be free from the influence of environment and temperature change, and the time interval can be adjusted at will, with high-speed instantaneous strong vibration. The utlity model has the functions of reqularly cleaning the materials on the screen,solving the problem of pasting the screen, areatly improving the sieve penetration rate and remarkable economic benefits.

2. Full seal design: due to the use of seal structure design, the previous slurry receiving chute on the screen has been cancelled, so as to reduce the occurrence of running, emitting and leaking of slury on the screen,greatly improving the working environment of workers and greatly reducing the labor intensity.
