linear vibrating screen is mainly composed of box type vibration exciter, screen box, vibration damping spring, support and driving device, and the running amplitude track is linear. The screen machine can be arranged horizontally or at an inclined angle. It is widely used in wet classification, dewatering, demineralization, tailings dry discharge and other process links in mineral processing, coal preparation, gravel aggregate, building materials, chemical industry and other industries. The screen surface structure is generally divided into single layer or double layer. The model of screen unit can be customized according to customer requirements.
The vibration force of swing vibration tumbler screen generated by the drive device is an inertial force that changes in a certain pattern. The screening motion is a reciprocating inertial force generated by the rotation of the eccentric wheel driven by the motor around a fixed axis. The screen surface is generally horizontal or slightly inclined. After the sieve machine is started, the screen body reciprocates back and forth under the action of inertial force, so that the materials on the screen surface follow the screen box and performs a rotary motion on the plane to complete the screening work, the basic rotary motion is very similar to manual screening.
Nominal Aperture Size (mm) of Screening Elements | Stroke (mm) | Speed (rpm) | G Index (target) Loaded | |
Scalping | >75 | 12.0 - 10.5 | 750 - 800 | 3.8 |
Ballast | 75 to 32 | 10.0 - 8.5 | 850 - 900 | 4.0 |
Aggregates | 25.4 to 6.7 | 9.0 - 8.0 | 900 - 950 | 4.1 |
Fines Separation | <6.7 | 8.0 - 7.0 | 950 - 1000 | 4.0 |
