Vibrating conveyor vibration facilities methods

The bulk solid materials vibrating hopper and unloading hopper to the stored materials. Provide vibration method may be hit with a heavy hammer to simply hit the side wall of

the hopper, or oscillating device with complex activator end positions. Vibration frequency can be 14 ~ 1300Hz, amplitude from near zero to large

At 60mm.
Vibration that can discharge capacity and material transmitted vibration reduction due to vibration of the bulk solid material strength. If the material is stored in an airtight

container, low-frequency vibration will make the material more dense; frequency vibration may cause the material may also lead to material bulk density, which is

And the corresponding amplitude of the nature of the material. It should be noted that, in the flow of the material required by vibration of occasions when the portable conveyor hopper

discharge port vibrations must not be closed. This results because of the material in any form will arch strength increases.
The hopper or bulk solid materials provide effective vibration There are two basic methods, namely silo wall vibrations and vibrations are directly stored materials.
Warehouse wall vibration
Hopper wall vibration is generally compressed air or by using the external hopper wall mounted electric vibrator to vibrate. A pneumatic piston vibrator type, electromagnetic

type and the eccentric rotary type (electrical or pneumatic operation).
Pneumatic piston vibrators rapping hammer with the outer surface of the hopper; electromagnetic vibrator has a similar effect, both the wall perpendicular to the vibration

bucket; eccentric rotary vibrator is Belt conveyor a vibrating device more expensive, generally life than short, compared with other types of vibrators, the need to stay low

Amplitude, high frequency operation, this device can be successfully used to move the material difficult.
Vibrator To properly placed in a position to produce the best results; selected amplitude and frequency of vibration must be sufficient to destroy the material arch. Under

normal circumstances, only be determined by experiment, usually affecting factors vibrator summarized as follows:
Type. About amplitude and frequency selection has some experience and law: that is, for raw materials, the general should adopt the low-frequency, high amplitude; For fine

powdery material is just the opposite. The specification shall be suitable hopper vibrator beveled plate rigidity and size.
Installation. Recommended hopper vibrator mounted on a steel reinforcing plate slope, and storage of the material as much as possible to increase the contact surface. Its

location in the "center of pressure" surface.
Vibration force. In most practical applications, the force necessary to apply part of the material silo cone weight of 1/10. If the density of the material is greater than

1440kg, the applied force is the weight of the cone part of the material 1/7; if the material density greater than 1920kg, the applied force is funnel portion was

Material weight of 1/5.
