High-frequency electromagnetic vibrating screen is a new screen surface vibration screening machinery. The high-frequency electromagnetic vibration screen through the vibration system vibration sieve and sieve frame does not move, vibration system in resonance state. The machine has the advantages of low power consumption, no dynamic load, easy to repair, the screen surface is composed of a plurality of groups of vibration amplitude control system respectively, may at any time regulation. The screen is composed of individually tensioning composite screen mesh and a supporting net, self-cleaning ability, convenient replacement.

Features.

1regulation of vibration amplitude, is generally 1 -2 mm.

2high vibration frequency, up to3000 times per minute.

3screen surface vibration intensity, up to 9 times the acceleration of gravity, is generally3 times the sieve machine.

4small energy consumption, each group of electromagnetic vibration exciter power is 0.35KW.

The 5screen is a braided stainless steel wire, soft moderate replaced conveniently.

6the screening efficiency is high, is not easy to be blocked pores, large processing quantity.

Working principle.

The high-frequency electromagnetic vibration screen is a novel structure of electromagnetic vibration exciter as power source, each sieve machine is arranged a plurality of electromagnetic vibrator, the vibrator comprises an electric control box control, can be adjusted independently of electromagnetic vibration exciter vibration force, so as to achieve the design purpose of sorting. Electromagnetic vibration exciter is composed of an electromagnet, a vibrating rod, vibrating arm, stimulate dozen, rubber springs etc..

When the solenoid is energized by a rubber spring is deformed, drives the vibration rod and a vibrating arm vibration, through the vibration arm drive shaft torsional vibration for strikes strikes are installed at the upper end of screen body width of the rubber cap, which he holds the screen, and the vibration force to the screen, screen and screen body so as to achieve the real purpose.
