Exactly how to utilize and also keep wood pellet machine effectively?<br>
Grinding prior to utilizing

Many roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, and quenching process, there are typically lots of cloths inside the die openings, which might influence the pelletizing impacts as well as production. Consequently, before beginning a brand-new pellet machine, or after changing a new die, you require to grind it thoroughly.



We utilize oil mixture to process grind the roller and also level die. The oil combination is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you must readjust the clearance between roller and flat die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 minutes.



For ring die pellet mill, the grinding process requires more oil blend and longer time. The quantity of oil mix is 10% that of pellet manufacturing 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 raw materials

The suitable wetness content of biomass materials ought to in between 14% and 20%. Dry materials are hard to take shape, wet 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. Generally, the hole size of the pellet mill die is 6mm as well as 8mm, and the dimension of resources ought to be under 5mm, or they might block the holes and also reduce pellet manufacturing.



The sticky force establishes the forming price of the pellets Many biomass materials consist of lignin, which would certainly melt under heat as well as function as binder. But industrial pelletizer machine like rice husk has low glue pressure. It require to be mixed with sawdust or binders to make pellets



The thickness as well as size of the timber pellets.

The thickness of wood pellets is determined by the hole size of the die. The size is established by the slicer. In flat die pellet machine, the slicer is mounted 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 different sizes. For your very own usage, it is much better to be brief. For transport and selling, it recommend to be a little lengthy.




After the wood pellets come out from the pellet machine, they are warm with some heavy steams. They can be dried and also cooled down in an open area, or by a counter-flow cooler. Quick cooling down can improve the firmness of the timber pellets, and also promote storage space as well as transport.



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

When you ended up making pellets, do not close the pellet machine down at the same time. Include some mixed oil and biomass materials to the pellet machine and let it run for 1-2 minutes. This way, we can fill up the die holes with oil blend, to make sure that we can directly start making pellets the following time. With this process, we can not only keep the mold and mildew, yet likewise conserve time. When the pellet machine quits, loosen up the adjusting screw and clear away the left materials.



The upkeep of roller, die, shafts and transmission

You should remove all difficult items as well as metal blocks in basic materials prior to feeding them right into the pellet machine, or they would trigger damage to the roller, die or primary shaft. You can install a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can rise to 80 ℃, and the roller maintains high pressure during operation. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, and lube it with oil. After every 8 working hrs, the primary shaft demand to be oiled. Richi machine cleansing every half a year. If there is irregular high warmth in the gearbox, you can utilize much better equipment oil and also boost the clearance between the gears for upkeep. The fastening screw in the transmission component also need to be changed regularly.



Exactly how to change roller and die?

When the rollers wears out, you can change the roller shell or the entire set of roller. If the bearing get loosened or secured, you require to replace the bearing and also the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and also replace it with a brand-new one. If the ring die is taken care of with screws, you need to tremble the ring die gently, as well as get rid of the screw with also stamina.



In level die pellet machine, the level die is installed with maintaining nuts in the keyway. On pellet manufacturing equipment of the level die, there are 2 in proportion screw openings. You can use the screw vehicle driver to press them out, or use a magnet to pull them out. Throughout your pushing or pulling, keep the level die vibrating with a hammer, to make sure that the screw won't embeded the screw opening.




Defense of the drive engine

Pick the matched power according to the needed manufacturing. If the power is inadequate, the production will be reduced and also the pelletizing effect is poor. If the power is as well big, it will certainly eat even more power, accelerate the exhaustion, as well as reduce the life span of roller as well as die.



The exam and also repair must be accomplished in power off condition. The machine should be positioned near the functioning location, so as to decrease the relocating time as high as possible. Safeguard it from water logging, rainfall, electrical leakage, fire, etc.



Just when we use the pellet machine correctly as well as keep it regularly can we take full advantages of the pellet machine and prolong its functioning life.
