Vibrating conveyor installation and influencing factors





Installation vibrating conveyor
Vibrating conveyor trough installation method according to the driving mode, the load of the tank material and to determine the structure of the stent, the stent inherent

vibration and inertia do not sync.
Vibrating conveyor frame to withstand the reaction force of the vibration, vibrating conveyors installed in the interior, in order to avoid resonance, a higher natural frequency

to building a solid structure.
Vibrating conveyor is started or stopped, tuned to the vibration of the time was short, but it will cause a lot of abnormal vibration.
Vibrating conveyor stack height from the ground stents generally no more than 3m, if too high will increase the cost of the stent, it is not economical.
Wu balanced industrial belt conveyor 90 percent if vibration isolation effect and the frequency of about 600c/min, no problem using one bracket.
Vibrating conveyor can not be directly installed in the silo or hopper below the column of material because of the increased load damping effect, so that the design of dynamic

equilibrium become unbalanced, so the material must be fed through the feeder vibrating conveyor inside.

Factors and there are data
As mentioned above, the material being transported in a vibrating conveyor trough is the principle of the body to move forward with a tank larger than g acceleration forward and

upward movement, and when a sudden stop, the material particles by shock acceleration effects continue forward and upward. In a flash tank behind the rise again under this

When the first particle out of its own weight naturally fall into the groove surface, and subsequently with the tank up again, get acceleration, and then rushed forward at the

top, leaving the material continuously repeated so moving forward particle transport. food conveyor trough body of material handling speed and transmission capacity and

This principle has a close relationship. In fact, the material being transported particles in the tank body force and the trajectory is very complicated because the nature of

the material being transported with conveyor trough conveying movement is closely related to each other, influence the following factors:
The conveyor-related factors: the manner and vibration of the vibration angle; vibration frequency; vibration amplitude; conveyor inclination of the tank; tank stiffness; groove

shape and smoothness of the body; tank liner installation flexibility; existence of static electricity.
Factors relating to the nature and the material: the bulk density of the material; material particle size and shape; material particle size distribution; coefficient of internal

friction of the material; material coefficient of sliding friction; materials cohesion; material internal damping; the material body in the groove thickness.
From the above listed with tank and materials related to the nature of the various factors shows that, in calculating the vibrating conveyor speed of transport and transport

capacity, it is not just theoretical formula projections, should also include other relevant factors in order to obtain reasonable results. These factors and related information

To rely on experience and laboratory tests to get. In recent years, Europe and the United States published on vibrating conveyor speed of transport and delivery capacity

theories and formulas are different, many manufacturers of conveyor also made a lot of their own research and experimental work, but concluded

Rarely published.
