Just how to use and also keep timber pellet machine correctly?<br>
Grinding prior to using

A lot of roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, drilling, milling, and satiating procedure, there are typically numerous rags inside the die holes, which may affect the pelletizing effects and also production. Consequently, prior to starting a new pellet machine, or after replacing a brand-new die, you need to grind it extensively.



We utilize oil blend to refine grind the roller and also flat die. The oil mixture is made up of 20% great 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 in between roller as well as flat die to 0.1-0.3 mm. The grinding procedure must last 15-40 minutes.



For ring die pellet mill, the grinding process requires even more oil blend and longer time. The amount of oil combination is 10% that of pellet manufacturing per hr. The grinding time is 30-50 min. And also the clearance between ring die as well as the roller is 0.1-0.4 mm.



Pretreatment of raw materials

The suitable moisture web content of biomass products must in between 14% as well as 20%. Dry materials are hard to take shape, damp materials will make the pellets loose. The size of the raw materials must be less than the hole dimension of pellet mill dies. Typically, the hole dimension of the pellet mill die is 6mm and 8mm, and also the dimension of raw materials need to be under 5mm, or they may obstruct the holes as well as minimize pellet production.



The adhesive pressure identifies the developing rate of the pellets Most biomass products contain lignin, which would melt under heat and act as binder. However some materials like rice husk has low sticky force. It require to be combined with sawdust or binders to make pellets



The thickness and also length of the timber pellets.

The density of wood pellets is established by the opening size of the die. The size is determined 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 set up outside the ring die. Both of them can be adjusted to achieve different sizes. For your very own usage, it is better to be brief. For transportation and also selling, it advise to be a little long.



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



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

When you completed making pellets, don't shut the pellet machine down at the same time. Add some blended oil and also biomass products to the pellet machine and also allow it compete 1-2 min. By doing this, we can fill the die holes with oil mix, to make sure that we can directly begin making pellets the following time. With this procedure, we can not just preserve the mold and mildew, however also save time. When the pellet machine stops, loosen up the adjusting screw as well as clear away the left materials.




The maintenance of roller, die, shafts and transmission

You ought to eliminate all difficult items and also steel blocks in basic materials prior to feeding them right into the pellet machine, or they would certainly create damage to the roller, die or primary shaft. You can set up a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can reach up to 80 ℃, as well as the roller maintains high pressure during operation. As there is no dirt guard in the pellet machine, so you need to tidy up the bearing every 2-5 hours, and also oil it with oil. After every 8 functioning hrs, the major shaft need to be oiled. The transmission demand cleaning every half a year. If there is irregular high warm in the transmission, you can make use of better equipment oil and also increase the clearance between the gears for maintenance. The attaching screw in the transmission part additionally require to be replaced on a regular basis.



Just how to replace roller as well as die?

When the rollers wears, you can change the roller covering or the whole collection of roller. If the bearing get loosened or secured, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart as well as replace it with a new one. If the ring die is fixed with screws, you need to drink the ring die delicately, and also remove the screw with also stamina.



In level die pellet machine, the level die is set up with keeping nuts in the keyway. On the 2 sides of the flat die, there are two symmetrical screw holes. You can use the screw motorist to press them out, or utilize a magnet to draw them out. During small scale wood pellet production pushing or pulling, maintain the level die vibrating with a hammer, so that the screw will not embeded the screw opening.



Security of the drive engine

Choose the matched power according to the necessary production. If the power is inadequate, the production will be low and also the pelletizing impact is poor. If the power is too big, it will certainly take in more power, increase the weariness, and also shorten the life span of roller as well as die.



The examination and also fixing ought to be carried out in power off condition. The machine ought to be positioned near the functioning location, so as to lower the moving time as much as feasible. Protect richi pellet mill from water logging, rain, electric leak, fire, and so on.




Just when we utilize the pellet machine correctly as well as keep it consistently can we make the most of the pellet machine as well as prolong its working life.
