The square swing screen can also be called a reciprocating vibration screen or a precision vibration screen. The vibration force generated by the motor drive device is an inertial force that changes around a fixed axis and the direction changes regularly. The essence is that the eccentric wheel rotates around the fixed axis The reciprocating inertial force formed. According to the structural characteristics and working principle of the swing screen, the screen surface is generally horizontal or slightly inclined (inclination angle is 0°~5°)
The working principle of the square swing sieve is: after the swing sieve is started, the shaking body of the equipment, that is,the sieve box reciprocates back and forth under the action of inertia, and the sieve box and the sieve surface are periodically shaken, so that the material on the sieve surface With the screen box for directional jumping movement. During this period, the material smaller than the screen hole falls to the lower layer through the screen hole and becomes the under-screen. The material larger than the screen hole diameter is discharged from the discharge port after continuous tumbling and jumping movement, thereby completing the screening work.
