Analysis of the reasons for the blockage or non-feeding of the vibrating feeder

Vibrating feeder refers to a device that can uniformly, regularly and continuously feed block and granular materials from the storage bin to the receiving device. In the sand and gravel production line, the crushing machinery can be continuously and evenly fed, and the materials can be coarsely screened.

The vibrating feeder plays the role of a porter in the entire production process. If the vibrating feeder is blocked and spilled, it can directly lead to the production line not running. Therefore, it is crucial to ensure the normal operation of the vibrating feeder. important. The phenomenon that the silo is blocked in the vibrating feeder is caused by the following reasons:

1. From the analysis of the physical properties of the material, the main reasons for the blockage of the vibrating feeder are the stiffness and high water content.

2. During the outage of the vibrating feeder transportation system corresponding to the silo, due to the long storage time in the silo and the influence of humidity, the friction between the material and the silo wall increases, resulting in blockage.

3. There is too little material in the silo. Because the material falls from a height of more than ten meters, the deeper the depth of the vibrating feeder silo, the er the acceleration and the er the impact. Therefore, under the action of gravity, the material of a certain size gradually removes the storage at the bottom of the silo. The material is impacted and compacted; when the material is discharged again, blockage is likely to occur.

4. Structural blockage. The silo of the vibrating feeder is made of steel plate, and its shape is *ly cone, square cone or hyperbola with a large upper mouth and a small lower mouth. The material flows from * to bottom in the silo by its own weight, and the lower the flow section, the smaller the flow section, which is also an important cause of blockage.

5. Poor management of material storage points, resulting in large pieces of materials or foreign objects entering the warehouse. At the entrance of the silo of the vibrating feeder, the screen grate that is not set as required is too large, causing large pieces of material or foreign objects to enter the silo and cause blockage.

6. In the process of use, we should also pay attention not to directly press the load of the silo on the chute of the feeder, which will cause fatigue damage to the spring plate and the connecting fork for a long time, causing one of them to break.

7. It may be caused by too much feeding and too much feeding, resulting in the accumulation of materials in the machine base, the increase in the lifting resistance screw conveyor force, and the poor operation of the hopper. In this case, feed less immediately. and keep the feeding uniform.

8. The gap between the iron core and the armature of the feeder is too large or too small. If this happens, the feeding of the feeder will be affected because the machine cannot reach the normal amplitude.

9. It may be caused by the incompatibility between the various parts of the feeder, which are mainly caused by the loosening of some parts. This requires tuning adjustment of the components, adjusting the compression degree of the compression bolts of the machine spring plate to the *, so that the chute can reach the amplitude range specified by the production.
