Working principle of circular vibration screen machine

2015-08-12

Higao Tech offer the working principle of circular vibration screen machine for your better understanding of vibrating screening machines.
Circular vibrating screen is also called single axis vibrating screening machine. Vibration source of circular vibration screen is an inertial force which moves around a fixed axle direction and change as per positive regulations, its essence is the centrifugal force formed by the eccentric mass rotating around the fixed axis.

Working principle of circular vibrating screen is as follows:
After starting vibration screen machine, the vibrator of the screening machine will do directional jumping movement together with the vibrating screen box. Meanwhile, the materials less than the screen mesh will get through the screen surface to the lower layer, other materials bigger than the screen mesh will do continuous jump on the screen surface and then output from the discharge gate, so far the whole screening work is finished finally. According to the characteristics of its structure and working principle of circular vibration screening machine, the screen surface is generally fixed inclined (slope angle is 15 to 25 degrees).

From the structure and working principle of circular vibrating screening machine, you can see that the rotating direction of the vibrator has consequent flow direction and reverse flow direction relative to the direction of material flow. Obviously, when the vibrator do consequent rotation, the moving speed of materials will be improved, which can increase production capacity, but the screening efficiency will decrease; when the vibrator rotate along counter-current direction, the materials running speed would slow down, which can cause smaller production ability, but screening efficiency will be improved. In the light of this situation, during the actual screening operations, we could make our own choice between the production capacity and screening efficiency according to the specific questions and requirements to make the profit maximum.
