1. Definition and Use
Vibrating feeder (also known as vibrating feeder) is mainly used to evenly and continuously convey lumpy and granular materials from the silo to the receiving device, and at the same time, the materials can be coarsely screened. It is commonly used in sand and gravel production lines, metallurgy, coal mines, building materials and other industries, as a key component of crushing and screening combined equipment.
Second, the working principle
2.Excitation source driven
The equipment generates excitation force through a vibrating motor or a double eccentric shaft exciter, so that the trough vibrates in a periodic linear manner along the inclination direction.
Vibrating motor: The two motors run synchronously in the opposite direction, canceling the transverse force and retaining only the longitudinal excitation force.
Double eccentric shaft: the active and passive shafts rotate in the opposite direction, and transmit power through gear meshing to adapt to the impact of large materials.
Material movementThe material jumps forward along the parabolic trajectory under the action of vibration to achieve continuous conveying.
3. Structural composition
Core components
Tank body: bearing materials, using U-shaped or steel plate structure, some models with grate strips for screening.
Exciter: A vibrating motor or eccentric shaft assembly that adjusts the excitation force to control the flow rate.
Spring mounts: cushion vibrations, support the groove and absorb shocks.
Auxiliary design
Sealed body: prevent dust leakage and adapt to environmental protection needs.
Frequency conversion speed regulation: dynamic flow control is realized through motor frequency adjustment
