Reasons and solutions for the wood pellet machine not discharging

 




In recent years, the sales of wood pellets have been booming, and the wood pellet machine for sale have also gone online. Many bosses bought wood pellet machines for biomass, straw and sawdust pellet production, but they did not discharge after a period of operation. we summed up the most feedback from customers, and summarized some of the reasons and solutions for the non-discharge of the pellet machine.

The common reasons for not discharging of the wood pellet machine are:

1. The moisture content of the material is inappropriate.
Too much or too little moisture in the material will cause the die hole to be blocked, causing the wood pellet machine to fail to discharge the material. In this case, the boss should check the summarized materials and control the moisture content between 10%-15%.

2. The mold pressure plate and the pressure roller are severely worn. The die platen and the pressure roller are the main parts of the pellet machine, and they are also vulnerable parts. If the parts are aging or malfunction, these are also the reasons that the wood pellet machine will not discharge. If it is a newly purchased wood pellet machine, you only need to look at which parts are not working to distinguish the problem. If it is a pellet machine that has been used for many years, it means that the parts are aging, and you can just replace the parts.

3. The mold compression ratio is inappropriate. 
Different materials require different compression ratio molds. If you choose a regular wood pellet machine manufacturer, you will customize it separately according to customer needs at the beginning. Generally, this problem will not occur. If the material is not discharged, check the compression ratio of the mold. If it is not suitable, replace the material mold.

4. The material has high crude fiber content. 
There are different types and powers of wood pellet mill for sale. For different types of pellet machines, the requirements for pelleting are also different. Some pellet machines are suitable for special pressing of coarse fibers, and some are suitable for special pressing of fine fibers. If you choose a small wood pellet machine to compress coarse fiber materials, it is also the reason why the pellet machine does not discharge. The solution is to communicate with the manufacturer and replace it with a wood pellet machine

5. The distance between the mold and the pressure roller is inappropriate. 
The wood pellet machine promotes the formation of pellets through the extrusion of the accessory roller and the die. If the distance is not appropriate, the pellet machine will not be able to discharge the material normally. The solution is to adjust the distance properly.

6. There is material accumulation in the wood pellet machine. 
After the wood pellet machine is produced, there will be some accumulations, and there will be no clean residue. After the next wood pellet machine is operated, due to the high temperature, it will solidify into a hard block, so the wood pellet machine cannot discharge the material normally. The solution is to clean the inside and clean up the residue.

How to adjust the gap between the pressure roller of the biomass pellet making machine and the ring die?

  The gap between the pressure roller and the ring die is one of the important parameters adjusted during the operation of the biomass pellet making machine . The adjustment process is also one of the important adjustment steps before the operation of the biomass pellet making machine. The rationality of the gap adjustment will directly affect the use of the biomass pellet making machine. Correct adjustment can save the cost of biomass pellet making machine and improve economic benefits. This article introduces 5 kinds of small knowledge about the adjustment of the gap between the pressure roller and the ring die of the biomass pellet machine:   In general, the rotation direction of the biomass pellet mill ring die is clockwise. For a biomass pellet machine equipped with two rollers, the largest eccentric flange of the left roller should be installed in the upper left half of the ring die when the roller is installed. Zone, the largest eccentric flange of the right press rolle...

Common faults and maintenance methods of biomass pellet making machine

  The normal operation of the biomass pellet making machine can ensure the production efficiency, so the daily maintenance and maintenance of the biomass pellet making equipment is very important. Due to the long-term operation of the biomass pellet making machine, various failures will inevitably occur, which requires us to accumulate a wealth of experience in troubleshooting for a long time. The following is the maintenance method of our factory for the common faults of the biomass pellet making machine for your reference. Raw materials cannot enter the pelletizing room   Cause of issue: The conditioner is blocked or the feed port is arched Failure of the feeder auger transmission The feeder auger is blocked  Repair method: Clear the conditioner or feed port Check the feeder auger drive device and troubleshoot Clean the material on the feeder auger  There are raw materials entering the granulation chamber but no granules can be pressed Cause of issue: Die hole blo...

It is not recommended to buy a small wood pelletizer.

When customers buy wood pelletizer, we generally recommend choosing large ones instead of small ones, because larger models are more stable and durable. why? Let's start with the principle of the wood pelletizer. The principle of the wood pelletizer is that the pressure wheel strongly squeezes the sawdust through the holes of the die to form sawdust pellets. If you replace the abrasive tool or the pressure wheel with wood, can you still make pellets? Obviously not, then go a step further, the mold pressing wheel is made of iron, can it work? Certainly not. The larger the size of the wood pelletizer, the larger and thicker the grinding wheel, the greater the rigidity and strength of the overall model, while the strength of the raw wood chips is unchanged, so the larger the equipment, the more "labor-saving" it is to press, and the stability of the equipment The better the performance, the longer the service life. As the equipment increases, the processing difficulty of th...
