How to use and keep timber pellet machine effectively?<br>
Grinding prior to making use of

Many roller and level dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, as well as appeasing process, there are normally many rags inside the die openings, which may affect the pelletizing impacts and production. Therefore, prior to starting a brand-new pellet machine, or after changing a brand-new die, you require to grind it completely.



We use oil mixture to refine grind the roller as well as level die. The oil combination is made up of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you must change the clearance in between roller and also flat die to 0.1-0.3 mm. The grinding process must last 15-40 min.



For ring die pellet mill, the grinding procedure requires even more oil mixture and longer time. The amount of oil combination is 10% that of pellet production per hour. The grinding time is 30-50 minutes. As well as diy pellet making machine between ring die as well as the roller is 0.1-0.4 mm.




Pretreatment of basic materials

The appropriate moisture material of biomass products need to between 14% and 20%. Dry materials are upsetting form, wet materials will certainly make the pellets loose. The size of the raw products ought to be less than the hole dimension of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm and also 8mm, and also the dimension of raw materials need to be under 5mm, or they might obstruct the holes and also minimize pellet manufacturing.



The glue pressure identifies the forming price of the pellets Most biomass materials include lignin, which would melt under high temperature and act as binder. But some materials like rice husk has reduced adhesive force. It require to be mixed with sawdust or binders to make pellets



The thickness and also length of the wood pellets.

The density of timber pellets is figured out by the hole size of the die. The size is figured out 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 gotten used to attain different dimensions. For your very own use, it is better to be brief. For transportation and selling, it recommend to be a little lengthy.



After the wood pellets come out from the pellet machine, they are warm with some vapors. They can be dried and also cooled in an open field, or by a counter-flow colder. Quick cooling down can boost the firmness 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 completed making pellets, do not shut the pellet machine down simultaneously. Add some blended oil as well as biomass products to the pellet machine and also allow it run for 1-2 min. In this way, we can fill the die openings with oil combination, to make sure that we can directly begin making pellets the next time. With this procedure, we can not only preserve the mold and mildew, yet additionally save time. When the pellet machine quits, loosen the changing screw as well as eliminate the left materials.



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

You must get rid of all hard items and also metal blocks in raw materials prior to feeding them into the pellet machine, or they would certainly trigger damage to the roller, die or primary shaft. You can set up a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller sustains high pressure throughout procedure. As there is pellet grinder in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and also lube it with oil. After every 8 functioning hrs, the major shaft need to be oiled. https://linpvr.org/small-wood-pellet-mill/ cleansing every half a year. If there is abnormal high heat in the gearbox, you can make use of much better equipment oil and increase the clearance between the equipments for maintenance. The securing screw in the transmission component likewise require to be replaced on a regular basis.



How to change roller as well as die?

When the rollers breaks, you can replace the roller shell or the whole collection of roller. If the bearing get loose or locked, you need to change the bearing and also even the shaft.



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



In flat die pellet machine, the level die is set up with maintaining nuts in the keyway. On the 2 sides of the flat die, there are two balanced screw openings. You can use the screw vehicle driver to push them out, or utilize a magnet to draw them out. Throughout your pressing or drawing, maintain the flat die vibrating with a hammer, to ensure that the screw won't embeded the screw opening.



Protection of the drive engine

Pick the matched power according to the required production. If the power is not enough, the production will certainly be low and also the pelletizing result is poor. If the power is as well large, it will certainly eat even more power, speed up the exhaustion, and shorten the service life of roller as well as die.



The exam and repair work should be executed in power off problem. The machine needs to be positioned near the working area, so regarding minimize the moving time as high as possible. Secure it from water logging, rain, electric leak, fire, etc.



Only when we use the pellet machine appropriately as well as preserve it frequently can we maximize the pellet machine as well as extend its functioning life.
