Exactly how to utilize and also preserve wood pellet machine appropriately?<br>
Grinding before utilizing

A lot of roller and also flat dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, and satiating process, there are usually many dustcloths inside the die holes, which might influence the pelletizing results as well as production. As a result, before starting a brand-new pellet machine, or after replacing a new die, you require to grind it extensively.



We utilize oil mix to refine grind the roller and also flat die. The oil combination is composed of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mix to the pellet machine, you must readjust the clearance between roller and also level die to 0.1-0.3 mm. The grinding process should last 15-40 min.



For ring die pellet mill, the grinding process calls for more oil combination as well as longer time. The amount of oil blend 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 raw materials

The suitable moisture content of biomass products need to between 14% and also 20%. Dry materials are hard to take form, moist products will certainly make the pellets loose. The size of the raw materials need to be less than the hole dimension of pellet mill dies. Typically, the hole dimension of the pellet mill die is 6mm and 8mm, as well as the dimension of basic materials ought to be under 5mm, or they may obstruct the holes as well as minimize pellet manufacturing.



The sticky pressure establishes the forming price of the pellets Many biomass products have lignin, which would thaw under heat and also function as binder. Yet some products like rice husk has low sticky force. It require to be combined with sawdust or binders to make pellets



The thickness and also length of the timber pellets.

The density of timber pellets is determined by the opening dimension of the die. The length is established by the slicer. In flat 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 adjusted to achieve various dimensions. For your very own usage, it is better to be short. For transportation as well as marketing, it advise to be a little lengthy.



After the wood pellets come out from the pellet machine, they are warm with some vapors. They can be dried out and also cooled down in an open field, or by a counter-flow colder. Quick cooling down can boost the hardness of the timber pellets, as well as assist in storage space as well as transport.



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

When you ended up making pellets, don't close the pellet machine down at once. Include some blended oil as well as biomass products to the pellet machine as well as let it run for 1-2 min. This way, we can fill the die openings with oil blend, so that we can directly begin making pellets the next time. With this process, we can not just preserve the mold, yet likewise save time. When the pellet machine quits, loosen up the adjusting screw as well as eliminate the left materials.



The maintenance of roller, die, shafts as well as transmission

You should get rid of all difficult objects and metal blocks in basic materials before feeding them into the pellet machine, or they would create damages to the roller, die or primary shaft. You can set up a tubular magnet on the feed receptacle.




The warm inside the pelletizing chamber can reach up to 80 ℃, and the roller sustains high pressure throughout operation. As there is no dust protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, and lubricate it with oil. After richi pellet machine , the main shaft need to be fueled oil. The gearbox demand cleansing every half a year. If there is uncommon high heat in the gearbox, you can make use of better gear oil and also raise the clearance in between the gears for upkeep. The attaching screw in the transmission component additionally require to be changed frequently.



Exactly how to replace roller as well as die?

When the rollers wears out, you can change the roller covering or the whole collection of roller. If the bearing get loosened or secured, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, just loosen up the hoop chuck, take the old ring die apart and change it with a new one. If https://www.designingbuildings.co.uk/wiki/The_functioning_process_of_the_chicken_feed_factory is fixed with screws, you need to drink the ring die delicately, as well as remove the screw with even stamina.



In flat die pellet machine, the flat die is installed with maintaining nuts in the keyway. On the 2 sides of the flat die, there are two symmetrical screw openings. You can make use of the screw driver to push them out, or use a magnet to draw them out. Throughout your pressing or pulling, maintain the flat die shaking with a hammer, so that the screw will not stuck in the screw opening.



Security of the drive engine

Choose the matched power according to the necessary production. If the power is not nearly enough, the production will be low and the pelletizing effect is poor. If the power is as well large, it will certainly consume even more power, speed up the weariness, and also shorten the service life of roller and die.




The exam as well as repair service must be executed in power off problem. The machine should be placed near the working area, so regarding decrease the moving time as much as feasible. Safeguard it from water logging, rain, electrical leak, fire, etc.



Just when we make use of the pellet machine effectively and also keep it frequently can we maximize the pellet machine and also lengthen its functioning life.
