Swinging vibrating screen introduction :

From the vibration of vibrating screen is the screen box body movement track, also known as the rotary swing sieve sieve, sieve rocking vibration force driving device is generated by the inertia force of a rotating around a fixed axis, direction changed regularly, its essence is by eccentric mass rotating around a fixed axis formed by centrifugal force. According to the structural characteristics and working principle of swing sieve, the screen surface is horizontal or slightly inclined arrangement (tilt angle: 0 ° - 5 °). The working principle of the swing sieve: three-dimensional composite movement under the effect of the vibration sieve machine body vibration sieve box on the screen box, drive the screen surface vibrates periodically, so that the screen material along with the screen box with directional jumping movement. In the meantime, less than sieve aperture material through the sieve fell to the bottom, become the undersize sieve aperture, larger than the material through continuous roll jump after discharged from the discharge opening, complete the screening work finally. The structure and working principle of the swinging screen can be seen, the vibration exciter eccentric relative phase on the material track and material in the sieve surface influence the retention time is critical, i.e. the sieve machine processing ability and screening efficiency have the opposite effect, therefore, in the actual screening operations, we according to the specific circumstances and needs, trade-offs in the two aspects of the production ability and the screening efficiency.
