Copper Ore Beneficiation Line Gold Production Equipment Selling in Africa High Frequency Screen
The high frequency vibrating screen elastic system is double particle forced vibration system,according to
the resonance theory come from the theory of mechanical vibration,put the natural frequency ω ° come
from the mechanical equipment tuned similar to the frequency of electromagnetic vibration force ω.Make
the ratio is Z=0.9,the machine works in the resonance state with the lower critical near resonance,so that
make the entire machine has small volume,with low power consumption, high processing capacity,with
stable work.
When the circuit is connected on the external voltage,by the effect of controllable silicon,conductive in
the positive half cycle,when the electromagnetic coil turned on current,it generates a pulse magnetic force
between the armature and the iron core,make the mutual attraction between the armature and the iron core
(the sieve body moves upward),at this time,the energy storage spring plate stores certain amount of
potential energy;in the negative half cycle,the controllable silicon without electric conduction,without
producing the electromagnetic force,the potential energy stored by the spring plate is released,make the
armature and the iron core move in the opposite direction (the sieve body moves downward),so the screen
body make frequency reciprocating vibration with alternating current power supply (such as the current
frequency is 50HZ,the screen body vibrating frequency is 3000/m).
Before ex-factory,the machine has been adjusted,so the equipment in using process,not allowed to
increase the sieve body weight or change the number of pieces of the spring plate,otherwise,the adjusted
elastic system will be destroyed.
After installing the spring plate,tighten the three compression screws,you need to check and tighten
all the screws and nuts every day in the first month,make sure it has the right air gap;check once every
other day in the second month,until all the screws and nuts fastened,the equipment running stably.
