How to make use of as well as keep wood pellet machine properly?<br>
Grinding prior to making use of

The majority of roller and also level dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, as well as quenching process, there are generally many dustcloths inside the die openings, which might influence the pelletizing impacts as well as manufacturing. Therefore, prior to beginning a new pellet machine, or after replacing a new die, you require to grind it extensively.



We use oil mixture to refine grind the roller and flat die. The oil mixture is made up of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil blend to the pellet machine, you need to change the clearance in between roller as well as flat die to 0.1-0.3 mm. feed pellet machine for sale grinding process should last 15-40 minutes.



For ring die pellet mill, the grinding process requires even more oil mixture and also longer time. The amount of oil mix is 10% that of pellet manufacturing per hour. biomass pellet maker grinding time is 30-50 minutes. And also the clearance between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The suitable dampness content of biomass materials should between 14% and also 20%. Dry products are hard to take shape, moist materials will certainly make the pellets loose. The dimension of the raw products should be less than the hole size of pellet mill dies. Typically, the hole size of the pellet mill die is 6mm and also 8mm, and the dimension of resources should be under 5mm, or they might obstruct the holes and decrease pellet manufacturing.



The adhesive force establishes the creating rate of the pellets The majority of biomass products contain lignin, which would certainly melt under high temperature and also serve as binder. But some products like rice husk has low adhesive pressure. It need to be blended with sawdust or binders to make pellets



The density and also size of the wood pellets.

The thickness of timber pellets is determined by the opening size of the die. The length is established by the slicer. In flat die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be gotten used to achieve different sizes. For your own use, it is far better to be brief. For transport and selling, it recommend to be a little lengthy.



After the wood pellets appear from the pellet machine, they are warm with some steams. They can be dried and cooled down in an open field, or by a counter-flow cooler. Quick cooling can enhance the solidity of the wood pellets, as well as promote storage space and also transportation.



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

When you finished making pellets, don't close the pellet machine down at the same time. Add some blended oil and also biomass materials to the pellet machine and let it run for 1-2 minutes. By doing this, we can fill the die openings with oil mix, so that we can directly begin making pellets the following time. With this process, we can not only preserve the mold, yet also save time. When the pellet machine stops, loosen up the adjusting screw and remove the left products.



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

You ought to get rid of all hard objects and steel blocks in basic materials prior to feeding them right into the pellet machine, or they would create damage to the roller, die or major shaft. You can set up a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can rise to 80 ℃, and also the roller sustains high pressure throughout procedure. As there is no dust guard in the pellet machine, so you require to tidy up the bearing every 2-5 hrs, as well as lubricate it with oil. After every 8 working hours, the primary shaft demand to be oiled. The transmission demand cleaning every half a year. If there is unusual high warmth in the transmission, you can use better equipment oil as well as raise the clearance in between the gears for upkeep. The fastening screw in the transmission part likewise need to be changed frequently.



Exactly how to change roller and die?

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




In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart and also replace it with a brand-new one. If poultry feed machine is fixed with screws, you require to drink the ring die gently, as well as eliminate the screw with also toughness.



In flat die pellet machine, the level die is mounted with keeping nuts in the keyway. On the 2 sides of the flat die, there are 2 in proportion screw holes. You can utilize the screw driver to push them out, or make use of a magnet to pull them out. During your pushing or pulling, keep the flat die vibrating with a hammer, to make sure that the screw will not embeded the screw opening.



Security of the drive engine


Pick the matched power according to the required manufacturing. If the power is insufficient, the manufacturing will be low and also the pelletizing result is poor. If the power is as well large, it will take in even more power, increase the exhaustion, and also reduce the life span of roller and die.



The examination and fixing ought to be accomplished in power off condition. The machine should be placed near the working area, so as to lower the moving time as high as possible. Shield it from water logging, rain, electrical leak, fire, and so on.



Only when we utilize the pellet machine effectively and also maintain it routinely can we take full advantages of the pellet machine and prolong its functioning life.
