Exactly how to use as well as preserve timber pellet machine properly?<br>
Grinding before using

Most roller and also level dies in pellet machine are refined by high-heat therapy. After planing, drilling, milling, and appeasing process, there are typically numerous rags inside the die holes, which might influence the pelletizing effects and also production. Therefore, before beginning a brand-new pellet machine, or after replacing a new die, you need to grind it extensively.



We use oil blend to process grind the roller as well as level die. The oil mixture is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil blend to the pellet machine, you ought to change the clearance between roller and level die to 0.1-0.3 mm. The grinding process needs to last 15-40 min.



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



Pretreatment of raw materials


The suitable dampness content of biomass materials need to between 14% and also 20%. Dry products are upsetting form, wet products will make the pellets loose. The size of the raw products should be less than the hole dimension of pellet mill dies. Typically, the hole size of the pellet mill die is 6mm as well as 8mm, and also the dimension of resources must be under 5mm, or they may block the holes and minimize pellet production.



The adhesive pressure identifies the forming price of the pellets Most biomass products include lignin, which would thaw under heat and function as binder. Yet some products like rice husk has reduced glue pressure. It need to be combined with sawdust or binders to make pellets



The density and length of the timber pellets.

The density of timber pellets is established by the hole dimension of the die. The length is determined by the slicer. In level die pellet machine, the slicer is mounted under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to achieve various dimensions. For your very own use, it is better to be brief. For transportation as well as selling, it suggest to be a little long.



After the wood pellets appear 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 down can boost the firmness of the timber pellets, and also assist in storage space and 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. Include some combined oil and also biomass products to the pellet machine and allow it compete 1-2 minutes. This way, we can fill up the die openings with oil mixture, to ensure that we can directly start making pellets the next time. With this procedure, we can not just preserve the mold and mildew, but also save time. When the pellet machine quits, loosen up the changing screw and also eliminate the left materials.



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

You need to eliminate all hard items as well as steel blocks in resources prior to feeding them into the pellet machine, or they would create damages to the roller, die or primary shaft. You can install a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can rise to 80 ℃, and also the roller maintains 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 hours, as well as oil it with oil. After every 8 functioning hrs, the primary shaft demand to be fueled oil. The transmission requirement cleaning every half a year. If there is uncommon high heat in the transmission, you can make use of much better equipment oil and increase the clearance between the equipments for maintenance. The fastening screw in the transmission component also need to be changed frequently.




How to replace roller and die?

When the rollers breaks, you can replace the roller shell or the entire set of roller. If the bearing get loose or locked, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart as well as change it with a new one. If the ring die is taken care of with screws, you require to drink the ring die delicately, and also eliminate the screw with also toughness.



In level die pellet machine, the level die is installed with maintaining nuts in the keyway. On the 2 sides of the flat die, there are two symmetrical screw holes. You can utilize the screw chauffeur to push them out, or utilize a magnet to pull them out. During your pressing or pulling, maintain the level die shaking with a hammer, to make sure that the screw will not embeded the screw opening.



Protection of the drive engine

Pick the matched power according to the needed production. If floating fish feed pellet mill is not enough, the production will be low as well as the pelletizing result is poor. If the power is also big, it will certainly take in more power, accelerate the fatigue, and also shorten the service life of roller as well as die.



The exam and also fixing ought to be executed in power off problem. The machine ought to be put near the functioning area, so regarding lower the moving time as much as possible. Shield richi pellet machine from water logging, rainfall, electrical leakage, fire, etc.



Only when we make use of the pellet machine appropriately as well as keep it routinely can we make the most of the pellet machine and extend its working life.
