Vibrating feeder, in the production process, the blocky and granular materials can be uniformly, regularly and continuously fed from the hopper to the receiving device. In the sand and gravel production line, the crushing machinery can be continuously and uniformly fed, and the materials are coarsely screened. It is widely used in the crushing and screening combined equipment for metallurgy and coal mines beneficiation, building materials, the chemical industry and abrasives, etc. The occurrence of vibrating feeder material blockage and blanking, serious may lead to production line paralysis, the following introduction of several causes of material blockage and solutions is to give you a reference.
Causes and solutions of vibrating feeder blockage
1. Poor material fluidity
If the material in the feeder is too wet or viscous, causing the material to flow smoothly during the vibration process. For wet or viscous materials, the material can be pre-processed at the front end of the feeder, such as by heating, drying and other methods, so as to improve liquidity.
2. Insufficient degree of vibration
The feeder's vibration force is insufficient which can not overcome the weight of the material, resulting in the material can not fall normally, the material accumulates in the feeder, blocking the material channel, the following are several reasons for the lack of vibration force and solutions.
(1).The vibration motor does not have enough power
Check whether the rated power of the vibration motor meets the needs of material transportation. If you need to improve, you can replace the vibration motor with more power.
(2).Amplitude is not set properly
If the amplitude is too small, it will lead to poor material transportation, and if the amplitude is too large, it will easily damage equipment and increase energy consumption. The size of the amplitude can be adjusted according to the material characteristics and machine parameters to achieve better material conveying results.
(3).Improper setting of the speed governor
The feeder frequency of sampling should be matched with the frequency of operation, and the vibration motor frequency can be matched with the equipment by adjusting the speed governor to improve the vibration force.
(4).Aging or damaged equipment
If the equipment is used for a long time, there may be problems such as increased friction, wear of parts, looseness, etc., which will directly affect the vibration force of the equipment. The equipment can be regularly checked for maintenance to replace damaged or aging parts to ensure the stability of the long-term operation of the equipment.
3. Foreign object blockage
The presence of impurities in the feeder, such as a foreign object or metal fragments, these impurities will block the material flow in the feeder, resulting in no blanking, this situation checks cleaning up foreign bodies on a regular basis, checking whether there are deformities or large particles inside the feeder and other debris, and timely clean up.
4. Improper installation of equipment
For example, when the installed feeder is imbalanced, a too-small slope, magnetic body adsorption and other conditions, will affect the working effect of the feeder, resulting in blockage or blank material. In this case, the equipment should be installed reasonably, and the equipment should be operated in strict accordance with the instructions when installation to ensure that the equipment is balanced, the appropriate slope, and the isolated magnet to ensure that the stability training and material are not affected. After the completion of the installation, the equipment should be tested and debugged to check whether the components are operating normally and adjust the parameters according to the actual situation to achieve good working conditions.
5. Blockage of the internal structure
If the inside structure of the feeder has design defects such as right angles or dead angles, it may cause the material to accumulate and get stuck during the flow process, leading to material blocking. The solution to this situation should be to optimize the internal structure, for right angle, dead angle defects and other problems, can be optimized and improved, improve the flow of materials.
6. Abnormalities in the power supply
The feeder power supply is abnormal, such as too high or too low voltage, which will also affect the working state of the vibrating feeder, resulting in no blanking or blocking, this time to ensure that the feeder power supply is normal, free from external interference.
Vibrating feeder, as one of the important auxiliary equipment in the production line, its operation directly affects the stability and the efficiency of the entire production line. Therefore, it is necessary to regularly check and maintain the feeder, check the feeder frequently, and deal with problems in a timely manner to ensure that the equipment works normally.
