Exactly how to utilize and maintain wood pellet machine properly?<br>
Grinding before using

A lot of roller and also level dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, and quenching process, there are generally numerous rags inside the die openings, which might affect the pelletizing impacts as well as manufacturing. Therefore, before beginning my website , or after replacing a new die, you require to grind it thoroughly.



We utilize oil combination to process grind the roller as well as level die. paper pellet making machine is made up of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding richi pellet machine to the pellet machine, you need to change the clearance between roller as well as level die to 0.1-0.3 mm. The grinding process must last 15-40 min.



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



Pretreatment of basic materials

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



The glue pressure figures out the developing rate of the pellets Most biomass materials include lignin, which would certainly thaw under high temperature and also serve as binder. However some products like rice husk has low adhesive pressure. It need to be mixed with sawdust or binders to make pellets



The thickness and size of the wood pellets.

The thickness of timber pellets is identified by the opening dimension of the die. The size is determined by the slicer. In level die pellet machine, the slicer is installed under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to achieve various sizes. For your own usage, it is much better to be short. For transport as well as marketing, it recommend to be a little long.



After the timber pellets appear from the pellet machine, they are hot with some steams. They can be dried out as well as cooled down in an open area, or by a counter-flow cooler. Quick cooling down can boost the solidity of the timber pellets, as well as assist in storage and transportation.





Do not close down the machine right after making pellets.

When you finished making pellets, do not shut the pellet machine down at once. Add some combined oil as well as biomass materials to the pellet machine and also allow it compete 1-2 minutes. By doing this, we can load the die holes with oil mixture, to make sure that we can directly begin making pellets the next time. With this procedure, we can not just maintain the mold, however additionally save time. When the pellet machine quits, loosen the readjusting screw as well as eliminate the left products.



The upkeep of roller, die, shafts and transmission

You need to eliminate all difficult objects and also metal blocks in basic materials prior to feeding them into the pellet machine, or they would trigger damage to the roller, die or primary shaft. You can set up a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can rise to 80 ℃, and the roller maintains high pressure throughout procedure. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, and also lubricate it with oil. After every 8 functioning hrs, the main shaft requirement to be oiled. The transmission requirement cleaning every half a year. If there is unusual high heat in the gearbox, you can make use of far better gear oil and also boost the clearance in between the gears for maintenance. The attaching screw in the transmission part likewise require to be changed routinely.



How to replace roller as well as die?

When the rollers breaks, you can change the roller shell or the whole set of roller. If the bearing obtain loose or secured, you require to replace the bearing and even the shaft.



In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart and also change it with a brand-new one. If the ring die is fixed with screws, you need to tremble the ring die gently, and eliminate the screw with even stamina.



In flat die pellet machine, the flat die is mounted with retaining nuts in the keyway. On the 2 sides of the flat die, there are 2 in proportion screw holes. You can use the screw vehicle driver to push them out, or make use of a magnet to draw them out. Throughout your pushing or drawing, keep the level die shaking with a hammer, to make sure that the screw won't stuck in the screw hole.



Defense of the drive engine

Select the matched power according to the required production. If the power is not enough, the manufacturing will certainly be reduced and the pelletizing impact is poor. If the power is also large, it will take in more power, accelerate the exhaustion, and shorten the service life of roller and die.



The exam as well as repair ought to be performed in power off condition. The machine needs to be positioned near the functioning place, so regarding lower the moving time as high as possible. Safeguard it from water logging, rain, electrical leak, fire, etc.



Just when we utilize the pellet machine appropriately as well as keep it regularly can we make the most of the pellet machine as well as lengthen its working life.
