One trick to teach you to solve the blockage of wood pellet mill

The wood pellet mill often encounters blockage during use, which makes many users troubled. Let’s first look at the working principle of the sawdust granulator, and then analyze the causes and treatment methods of clogging.

The working principle of the wood chip granulator is to pulverize large wood chips with a pulverizer, and the length and water content of the material particles are within the specified range. finished product. However, some operators will block the wood pellet machine due to improper operation in various aspects when using the wood pellet machine. How do you deal with this problem?
In fact, the sawdust pellet machine often encounters blockage during use, which makes many users troubled. Clogging of the pulverizer may be a problem with the design of the tool, but it is more caused by improper use and operation.

1. The discharge pipe is not smooth or blocked. If the feed is too fast, the tuyere of the pulverizer will be blocked; improper matching with the conveying equipment will cause the discharge pipeline to be weakened or blocked after no wind. After the fault is detected, the ventilation openings should be cleared first, the unmatched conveying equipment should be changed, and the feeding amount should be adjusted to make the equipment operate normally.

2. The hammer is broken and aged, the screen mesh is closed and broken, and the water content of the pulverized material is too high, which will cause the pulverizer to be blocked. Broken and aged hammers should be updated regularly, the screen should be checked regularly, and the moisture content of the crushed materials should be lower than 14%. In this way, the production efficiency can be improved, and the pulverizer is not blocked.

3. The feeding speed is too fast and the load increases, causing blockage. Blockage will overload the motor, and if overloaded for a long time, it will burn out the motor. In this case, the material gate should be reduced or closed immediately, and the feeding method can also be changed, and the feeding amount can be controlled by increasing the feeder. There are two kinds of feeders: manual and automatic, and the user can choose according to the actual situation. Due to the high speed of the pulverizer, the large load, and the strong fluctuation of the load, the current of the pulverizer is generally controlled at about 85% of the rated current when it is working. In addition, in the production process due to power failure or other reasons, the stamper is blocked, especially the small-diameter stamper is difficult to clean. Many users usually use an electric drill to drill the material, which is not only time-consuming, but also easy to damage the finish of the die hole. .


Summarizing many years of practical experience, it is believed that the more effective method is to cook the ring die with oil, that is, use an iron oil pan, put waste oil into it, put the blocking die in the oil pan, and make the blocking die holes all immersed in the oil. Then heat the bottom of the oil pan until the material in the blocked die hole has a popping sound, that is, take out the blocked die, re-install the machine after cooling, adjust the gap between the die rolls, and restart the machine according to the operation requirements of the granulator, and the blocked die can be quickly removed. The material is cleaned up without damaging the finish of the die hole.

How to deal with the blockage of the wood pellet mill I believe that when you encounter similar problems, you can quickly find the cause and solve the problem. For more information about the granulator, please continue to pay attention to our website.
