After operating for some time, the biomass pellet machine stopped feeding and even emitted high-temperature smoke. What's going on here? Today, the biomass pellet machine manufacturer will discuss some reasons and solutions for the machine not feeding and emitting smoke.
1. The moisture content of the materials is inappropriate. Either too much or too little moisture in the materials will cause blockage of the mold holes, resulting in the machine not feeding. It is recommended to check the summarized materials and control the moisture content between 10% and 15%.
If there is no feeding, check the mold compression ratio. If it is not suitable, replace the material mold.
2. The ring mold and the roller are severely worn. The ring mold and the roller are the main components of the pellet machine and also easily damaged parts. During production, it is necessary to pay attention to their conditions. If there is wear, they need to be replaced.
3. The mold compression ratio is not appropriate. Different materials require different compression ratios for the molds. Choose regular large manufacturers such as Shandong Taichang Machinery's ring mold pellet machine series. They are usually not prone to this problem if customized according to customer needs at the beginning. If there is no feeding, check the mold compression ratio. If it is not suitable, replace the material mold.
4. The coarse fiber content of the materials is high. Biomass pellet machines have different models and power levels. For different models of pellet machine, the requirements for granulation are also different. Some pellet machines are suitable for pressing coarse fibers, and some are suitable for pressing fine fibers. If a small-sized pellet machine is used to press coarse fibers, it is also a reason for the machine not feeding.
5. The distance between the mold and the roller wheel is inappropriate. The pellet machine is formed by the compression of the accessories, the roller wheel and the mold. If the distance is inappropriate, it will also cause the machine not to feed normally. The solution is to adjust the distance to be appropriate.
The manufacturer of the biomass pellet machine reminds everyone that during the initial operation stage, more raw materials should be added. During the running-in period, the output of the newwood pellet machine must be lower than the rated output.
6. There is accumulated material inside the biomass pellet machine. After production, there will be some accumulations of materials. Unremoved residues will remain after the next operation of the pellet machine. Due to the high temperature, they will solidify into hard lumps, causing the machine to be unable to feed normally. The solution is to clean the interior and remove the residues.
7. The temperature of the main shaft head rises too high. The main shaft bearing clearance is too small. It is recommended to loosen the tightening nut appropriately.
8. The safety pin is broken, and hard foreign objects enter the pellet machine room. It is recommended to remove the foreign objects and replace the safety pin.
9. The pellet machine emits smoke, the scraper is worn, and the V-belt tension is insufficient. It is recommended to install a new scraper, tension the V-belt, remove hard materials, and lubricate the main bearing until the grease emerges from the rear support plate.
These are the reasons and solutions for the machine not feeding and emitting smoke. The manufacturer of the biomass pellet machine reminds everyone that during the initial operation stage, more raw materials should be added, and the output of the newwood pellet machine must be lower than the rated output during the running-in period.
