The working principle of the vibrating feeder

　　The working principle of the vibrating feeder is:

　　The vibrating feeder has a guiding trough in the lower part of the silo, and the bottom of the guiding trough is movable, and the bottom plate is reciprocated by a power device. When the bottom plate runs in the direction of the feeding port, the material moves along with the bottom plate, and the material is completed. Feeding process; when the bottom plate runs in the opposite direction, the material does not move with the bottom plate under the combined action of the internal pressure and the internal and external frictional forces; the bottom plate continuously circulates and reciprocates, and the material in the bin is continuously sent to the discharge port.

　　The disadvantages of vibrating feeders are:

　　Because the feeding frequency is high, the noise is also large; the vibrating feeder is driven by high-frequency vibration, and its amplitude and frequency are greatly affected by the particle size and specific gravity of the material, so the feeding amount is unstable and the feeding amount is adjusted. It is more difficult; because it is fed by vibration, the feeder starts to oscillate and stabilizes at frequency and amplitude, but the vibration parameters are sensitive to the stress state of the bottom plate, so the bottom plate can not bear a large pressure, and the lower guide groove needs to be added. The result is an increase in the overall height of the silo and an increase in engineering investment.
