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.
