From the perspective of the motion trajectory of the screen machine's shaking body, that is, the screen box, the FYBS-I square swing screen is also called a reciprocating screen. The vibration force generated by its driving device is an inertial force around a fixed axis with a certain regular change in direction. Its essence It is the reciprocating inertia force formed by the eccentric rotating around the fixed axis. According to the structural characteristics and working principle of the FYBS-I swing screen, the screen surface is generally horizontal or slightly inclined (the inclination angle is 0°~5°). The working principle of the FYBS-I swing screen is: after the screen machine is started, the shaking body of the screen machine, that is, the screen box, reciprocates back and forth under the action of inertial force. The screen box drives the screen surface to shake periodically, so that the materials on the screen surface It performs a directional jumping movement together with the screen box. During this period, the particles smaller than the screen diameter fall to the lower layer through the screen holes and become under-sieve objects, which are larger than the screen diameter.
Materials with a large diameter are discharged from the discharge port after continuous rolling and jumping motion, and finally complete the work.
It can be seen from the structure and working principle of the FYBS-1 square swing screen that the eccentric wheel pitch of its transmission mechanism has a crucial impact on the movement trajectory of the material and the residence time of the material on the screen surface, that is, on the processing capacity and Screening efficiency has the opposite effect. In view of this, in actual screening operations, we can make a choice between production capacity and screening efficiency according to specific conditions and needs.
With the same or similar configuration, the FYBS-1 square swing screen has higher processing capacity and screening efficiency than the general inertial vibrating screen. Its essence is that this model can artificially control the movement trajectory and retention of materials on the screen surface. In time, that is, in a limited space, since the movement trajectory of the material is a non-linear curve with changes in speed and acceleration, the material has more chances of contact with the screen surface, which of course increases the screen penetration rate.
