Just how to utilize and keep timber pellet machine correctly?<br>
Grinding before making use of

Many roller and also level dies in pellet machine are processed by high-heat therapy. After planing, exploration, milling, and also quenching procedure, there are typically lots of rags inside the die openings, which may affect the pelletizing results and also production. For that reason, prior to beginning a new pellet machine, or after changing a brand-new die, you require to grind it extensively.



We use oil mixture to refine grind the roller as well as flat die. The oil mix is composed of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil combination to the pellet machine, you should change the clearance between roller as well as level die to 0.1-0.3 mm. The grinding procedure must last 15-40 minutes.



For ring die pellet mill, the grinding process calls for even more oil blend as well as longer time. The quantity of oil mix is 10% that of pellet manufacturing 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 appropriate moisture web content of biomass products need to in between 14% as well as 20%. Dry materials are upsetting form, wet products will certainly make the pellets loose. The dimension of the raw products must be less than the hole size of pellet mill dies. Generally, homemade pellet machine of the pellet mill die is 6mm and also 8mm, and also the dimension of resources need to be under 5mm, or they might obstruct the holes as well as reduce pellet production.



The sticky force determines the developing price of the pellets The majority of biomass materials contain lignin, which would thaw under heat and also work as binder. But some materials like rice husk has reduced glue pressure. It require to be combined with sawdust or binders to make pellets



The density and also length of the timber pellets.

The thickness of timber pellets is determined by the hole size of the die. The size is identified by the slicer. In level 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 gotten used to attain various sizes. For your own usage, it is far better to be brief. For transport and also marketing, it advise to be a little long.



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



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

When you ended up making pellets, do not shut the pellet machine down at the same time. Add some mixed oil and also biomass products to the pellet machine and let it run for 1-2 minutes. By doing this, we can fill up the die holes with oil blend, so that we can directly begin making pellets the following time. With this process, we can not only maintain the mold and mildew, however additionally save time. When the pellet machine quits, loosen the readjusting screw and also remove the left materials.



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

You should get rid of all hard things as well as metal blocks in resources before feeding them into the pellet machine, or they would certainly create damage to the roller, die or major shaft. You can mount a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure throughout operation. As there is no dirt protector in the pellet machine, so you need to tidy up the bearing every 2-5 hours, as well as lubricate it with oil. After every 8 functioning hours, the main shaft demand to be fueled oil. The transmission requirement cleaning every half a year. If there is disc pelletizer in the gearbox, you can use better equipment oil as well as raise the clearance between the gears for upkeep. The fastening screw in the transmission part likewise require to be changed consistently.



Exactly how to replace roller and also die?

When the rollers breaks, you can change the roller covering or the entire set of roller. If the bearing obtain loose or locked, you require to change the bearing and even the shaft.



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



In flat die pellet machine, the flat die is mounted with retaining nuts in the keyway. On the 2 sides of the level die, there are two in proportion screw holes. wood pellet production machine can use the screw motorist to press them out, or make use of a magnet to draw them out. During your pressing or pulling, maintain the level die vibrating with a hammer, to ensure that the screw will not stuck in the screw hole.



Protection of the drive engine


Pick the matched power according to the needed manufacturing. If the power is not nearly enough, the manufacturing will be reduced and also the pelletizing impact is poor. If the power is also huge, it will take in even more power, increase the exhaustion, and also shorten the service life of roller and also die.



The examination and also repair work should be performed in power off problem. The machine needs to be positioned near the functioning area, so as to lower the relocating time as high as feasible. Secure it from water logging, rain, electric leak, fire, etc.




Just when we use the pellet machine properly and preserve it consistently can we make the most of the pellet machine and also lengthen its functioning life.
