How to make use of and keep wood pellet machine appropriately?<br>
Grinding before using


The majority of roller and also flat dies in pellet machine are refined by high-heat treatment. After planing, drilling, milling, and also satiating procedure, there are normally lots of dustcloths inside the die holes, which might influence the pelletizing effects and production. Consequently, before beginning a new pellet machine, or after changing a brand-new die, you require to grind it thoroughly.



We use oil combination to process grind the roller and also level die. The oil combination is made up of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil mix to the pellet machine, you must adjust the clearance between roller and also level die to 0.1-0.3 mm. richi machinery grinding process needs to last 15-40 min.



For ring die pellet mill, the grinding procedure needs more oil blend as well as longer time. The quantity of oil combination is 10% that of pellet production per hr. The grinding time is 30-50 min. And the clearance in between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The appropriate wetness material of biomass products ought to in between 14% and also 20%. Dry products are hard to take form, damp products will certainly make the pellets loose. The dimension of the raw materials must be less than the hole size of pellet mill dies. Typically, the hole dimension of the pellet mill die is 6mm as well as 8mm, and the dimension of basic materials need to be under 5mm, or they may obstruct the holes as well as decrease pellet production.



The sticky pressure identifies the developing price of the pellets Most biomass products include lignin, which would thaw under heat and also function as binder. Yet some materials like rice husk has low adhesive pressure. It need to be blended with sawdust or binders to make pellets



The thickness as well as size of the wood pellets.

The thickness of wood pellets is figured out by the hole dimension of the die. The size is established by the slicer. In level die pellet machine, the slicer is set up under the level die, while in ring die pellet machine, the slicer is installed outside the ring die. Both of them can be adapted to achieve different dimensions. For your very own usage, it is far better to be brief. For transport and marketing, it suggest to be a little lengthy.



After the wood pellets appear from the pellet machine, they are warm with some vapors. They can be dried out and also cooled down in an open area, or by a counter-flow cooler. Quick cooling can improve the solidity of the wood pellets, and also promote storage and transportation.



Don't shut down the machine right after making pellets.

When you ended up making pellets, do not shut the pellet machine down simultaneously. Add some mixed oil and also biomass products to the pellet machine and also let it run for 1-2 minutes. By doing this, we can load the die holes with oil mixture, so that we can straight begin making pellets the next time. With this procedure, we can not just preserve the mold and mildew, however also save time. When the pellet machine stops, loosen up the changing screw as well as remove the left materials.



The maintenance of roller, die, shafts and transmission

You must get rid of all tough objects and also metal blocks in resources prior to feeding them into the pellet machine, or they would certainly trigger damage to the roller, die or primary shaft. You can install a tubular magnet on the feed hopper.



The heat inside the pelletizing chamber can reach up to 80 ℃, as well as the roller maintains high pressure during procedure. As there is no dust guard in the pellet machine, so you require to clean up the bearing every 2-5 hours, as well as oil it with oil. After every 8 working hours, the major shaft need to be oiled. The gearbox requirement cleansing every half a year. If there is irregular high warm in the transmission, you can utilize much better gear oil as well as raise the clearance between the equipments for upkeep. The securing screw in the transmission component likewise require to be changed routinely.



How to change roller as well as die?

When the rollers wears, you can change the roller shell or the entire collection of roller. If the bearing obtain loosened or secured, you require to change the bearing and also the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart and change it with a brand-new one. If https://richipelletmachine.blogspot.com/2022/09/whenacquiringamericanmadewoodpelletmill.html is repaired with screws, you need to drink the ring die delicately, as well as eliminate the screw with even strength.



In level die pellet machine, the level die is installed with retaining nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw holes. You can make use of the screw vehicle driver to push them out, or make use of a magnet to pull them out. Throughout your pushing or drawing, keep the flat die vibrating with a hammer, so that the screw won't embeded the screw opening.




Security of the drive engine

Select the matched power according to the necessary manufacturing. If the power is not nearly enough, the manufacturing will be reduced and also the pelletizing effect is poor. If the power is also large, it will certainly take in more power, accelerate the exhaustion, as well as reduce the life span of roller as well as die.



The exam and also repair service ought to be performed in power off problem. The machine needs to be positioned near the working area, so as to decrease the relocating time as much as possible. Shield it from water logging, rain, electric leak, fire, etc.



Only when we utilize the pellet machine appropriately as well as preserve it on a regular basis can we make the most of the pellet machine as well as prolong its functioning life.
