How to use as well as preserve wood pellet machine effectively?<br>
Grinding prior to using

Many roller as well as flat dies in pellet machine are refined by high-heat therapy. After planing, boring, milling, and appeasing process, there are normally numerous rags inside the die openings, which may influence the pelletizing results and manufacturing. As a result, before starting a new pellet machine, or after replacing a brand-new die, you require to grind it extensively.



We use oil mix to refine grind the roller as well as level die. The oil mix is composed of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil blend to the pellet machine, you need to readjust the clearance between roller and also flat die to 0.1-0.3 mm. The grinding process needs to last 15-40 minutes.



For ring die pellet mill, the grinding procedure needs more oil mix as well as longer time. The amount of oil blend is 10% that of pellet production 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 basic materials

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



The glue pressure identifies the forming rate of the pellets Most biomass materials contain lignin, which would thaw under high temperature and function as binder. But some materials like rice husk has low glue force. It need to be mixed with sawdust or binders to make pellets



The density and also size of the timber pellets.

The density of wood pellets is figured out by the opening size of the die. The length is determined by the slicer. In level die pellet machine, the slicer is set up under the level die, while in ring die pellet machine, the slicer is installed outside the ring die. pellet cutting machine of them can be adjusted to achieve different sizes. For rice husk pellet machine price , it is 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 hot with some heavy steams. They can be dried out and also cooled down in an open field, or by a counter-flow colder. Quick cooling can improve the solidity of the wood pellets, and also facilitate storage and transport.



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

When you ended up making pellets, do not shut the pellet machine down at once. Include some combined oil and also biomass products to the pellet machine and also let it compete 1-2 minutes. This way, we can fill up the die holes with oil mix, to make sure that we can directly start making pellets the following time. With this procedure, we can not only preserve the mold, yet additionally conserve time. When the pellet machine stops, loosen the adjusting screw as well as remove the left products.



The maintenance of roller, die, shafts and also transmission

You ought to get rid of all difficult things and metal blocks in resources prior to feeding them into the pellet machine, or they would certainly trigger damages to the roller, die or main shaft. You can install a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can rise to 80 ℃, and the roller sustains high pressure during procedure. As there is no dust guard in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and also lubricate it with oil. After every 8 functioning hrs, the primary shaft demand to be fueled oil. The gearbox need cleansing every half a year. If there is irregular high warmth in the gearbox, you can use far better equipment oil and also raise the clearance in between the equipments for maintenance. The attaching screw in the transmission component likewise need to be changed routinely.



How to replace roller as well as die?

When the rollers breaks, you can change the roller covering or the whole collection of roller. If the bearing obtain loose or locked, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, just loosen up 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 carefully, and get rid of the screw with also strength.




In flat die pellet machine, the level die is mounted with maintaining nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw openings. You can utilize the screw driver to push them out, or utilize a magnet to pull them out. Throughout your pushing or drawing, keep the flat die vibrating with a hammer, to make sure that the screw will not embeded the screw hole.



Protection of the drive engine

Pick the matched power according to the necessary manufacturing. If the power is not nearly enough, the production will be reduced and the pelletizing impact is poor. If the power is as well large, it will take in even more power, increase the fatigue, and shorten the life span of roller and also die.



The exam as well as repair should be carried out in power off condition. The machine should be put near the working area, so regarding minimize the relocating time as long as possible. Protect it from water logging, rainfall, electric leak, fire, and so on.



Just when we make use of the pellet machine effectively and maintain it on a regular basis can we make the most of the pellet machine and also extend its functioning life.
