How to use as well as keep wood pellet machine appropriately?<br>
Grinding prior to utilizing

The majority of roller as well as flat dies in pellet machine are refined by high-heat treatment. After planing, drilling, milling, and also relieving procedure, there are usually many dustcloths inside the die holes, which might influence the pelletizing impacts as well as production. Therefore, before beginning a brand-new pellet machine, or after replacing a brand-new die, you require to grind it thoroughly.



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



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



Pretreatment of basic materials

The ideal wetness material of biomass products must in between 14% and 20%. Dry materials are upsetting form, damp materials will certainly make the pellets loose. The dimension of the raw materials ought to be less than the hole dimension of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm and 8mm, as well as the dimension of resources need to be under 5mm, or they might obstruct the holes and lower pellet production.



The sticky pressure determines the creating rate of the pellets A lot of biomass products have lignin, which would thaw under heat and also act as binder. However some products like rice husk has reduced sticky pressure. It need to be blended with sawdust or binders to make pellets



The density and also size of the timber pellets.

The thickness of timber pellets is figured out by the opening dimension of the die. The length is determined by the slicer. In flat die pellet machine, the slicer is mounted under the flat die, while in ring die pellet machine, the slicer is set up outside the ring die. Both of them can be adapted to accomplish different sizes. For your very own use, it is better to be brief. For transportation as well as marketing, it suggest to be a little long.



After the wood pellets come out from the pellet machine, they are hot with some vapors. They can be dried out and also cooled in an open area, or by a counter-flow colder. Quick cooling can improve the hardness of the timber pellets, and also help with storage and transportation.



Do not shut down the machine right after making pellets.

When you completed making pellets, do not shut the pellet machine down at the same time. Add some combined oil and biomass products to the pellet machine and also let it compete 1-2 minutes. In this way, we can fill up the die holes with oil mix, to make sure that we can directly start making pellets the following time. With this procedure, we can not only preserve the mold, however likewise save time. When the pellet machine quits, loosen the readjusting screw as well as eliminate the left products.



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

You must get rid of all hard objects and steel blocks in basic materials prior to feeding them into the pellet machine, or they would trigger damages to the roller, die or major shaft. richi pellet mill can install a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure throughout procedure. As there is no dirt protector in the pellet machine, so you need to clean up the bearing every 2-5 hrs, and lubricate it with oil. After every 8 working hours, the primary shaft need to be oiled. The gearbox need cleansing every half a year. If there is rabbit feed pellet making machine in the transmission, you can utilize much better gear oil and also increase the clearance between the equipments for upkeep. The securing screw in the transmission part likewise need to be changed frequently.



Exactly how to change roller and also die?

When the rollers breaks, you can change the roller covering or the whole collection of roller. If the bearing obtain loosened or secured, you require to change the bearing as well as even the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart as well as replace it with a brand-new one. If the ring die is repaired with screws, you require to shake the ring die gently, and also get rid of the screw with even stamina.




In level die pellet machine, the flat die is mounted with preserving nuts in the keyway. On the 2 sides of the level die, there are 2 in proportion screw openings. You can make use of the screw vehicle driver to press them out, or use a magnet to draw them out. Throughout your pushing or pulling, maintain the flat die shaking with a hammer, to ensure that the screw won't embeded the screw opening.



Security of the drive engine

Pick the matched power according to the necessary production. If the power is insufficient, the manufacturing will certainly be low as well as the pelletizing impact is poor. If the power is too huge, it will eat even more power, increase the fatigue, as well as shorten the life span of roller as well as die.




The examination as well as fixing need to be carried out in power off condition. The machine needs to be placed near the working place, so as to lower the moving time as long as feasible. Shield it from water logging, rain, electrical leak, fire, etc.



Only when we utilize the pellet machine correctly and keep it on a regular basis can we make the most of the pellet machine and prolong its functioning life.
