Square Swing Screen

Introduction: The square swing screen can also be called a reciprocating vibrating screen or a precision vibrating screen. The vibrator generates vibration and swinging motion, which is transmitted to the screen surface, so that the material is quickly dispersed in front of the screen machine, thereby achieving efficient screening. The main structure includes a screen box, an exciter, a dual motor drive system, a rubber spring shock-absorbing module and a self-cleaning device.
Working principle: The vibration force generated by the square swing screen motor drive device is an inertial force that rotates around the fixed axis and changes in a certain regularity. It is essentially a reciprocating inertial force formed by the rotation of the eccentric wheel around the fixed axis. According to its structural characteristics and working principle, its screen surface is generally arranged horizontally or slightly inclined (the inclination angle is 0-5°). After the square swing screen is started, the screen box reciprocates back and forth under the action of inertial force, and the screen box and the screen surface are shaken periodically, so that the material on the screen surface moves in a directional jumping manner with the screen box. During this period, particles smaller than the screen hole fall through the screen hole to the lower layer and become screen undersize, and particles larger than the screen hole are discharged from the discharge port after continuous tumbling and jumping movements, thereby completing the screening work.
