Equilibrium criteria for vibration conveyor loader empty load and load test
Mar 16, 2018

The vibratory conveyor is a continuous conveying machine that vibrates the trough with an exciter, so that the trough material slides or moves in a certain direction, and is suitable for conveying various loose materials in a horizontal or inclined direction. In the process of conveying the vibrating conveyor, it can also perform screening, mixing, heating, cooling, drying, dewatering and other process operations, and thus corresponding goals.


But no matter what to do with a vibratory conveyor, it must be tested before it is officially put into operation. The first is an empty load test. First of all, it is required that the conveyor start smoothly and quickly, the vibration should be stable, and there should be no left and right swings, jumps, impacts and abnormal sounds.


Secondly, the amplitude and vibration direction angle of the vibrating conveyor shall not be greater than 10% of the rated value; the vibrating conveyor whose length is greater than 15m shall have a amplitude deviation of no more than 10% of the rated amplitude in the front, middle and rear sections; and The temperature rise of the rubber spring shall not exceed 50°C. The temperature rise of the metal spring shall not exceed 70°C. The temperature rise of the bearings and motors of the eccentric link vibration conveyor shall not exceed 50°C; the temperature rise of the electromagnet coil shall not exceed 65°C. When the above requirements are met, it can be determined that the vibratory conveyor has passed the empty load test.


Next, a load test is performed on the vibrating conveyor. At the same time, it is observed whether the material should move smoothly in the trough, there is no obvious resistance, deviation, swirling, and severe skip phenomenon; whether the amplitude reduction is not greater than the rated amplitude. 10%; The delivery volume is less than 90% of the rated delivery volume; only qualified can be put into use.


Before stopping the vibrating conveyor, the feeding should be stopped first, and the conveyor discharge can only be stopped after no material is discharged. However, when several vibratory conveyors are jointly operated, the parking sequence should be opposite to the starting sequence. This must be kept in mind.  http://www.wxconveyor.com
