Exactly how to utilize and also preserve timber pellet machine effectively?<br>
Grinding before utilizing

Many roller and flat dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, and also appeasing process, there are usually several cloths inside the die holes, which may affect the pelletizing effects and manufacturing. Therefore, prior to beginning a new pellet machine, or after changing a brand-new die, you need to grind it extensively.



We utilize oil mix to refine grind the roller and level die. The oil mixture is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil blend to the pellet machine, you should change the clearance in between roller as well as flat die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 minutes.



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



Pretreatment of raw materials

The ideal dampness content of biomass materials need to in between 14% and also 20%. Dry materials are hard to take form, damp products will certainly make the pellets loose. The size of the raw materials need to be less than the hole size of pellet mill dies. Usually, the hole size of the pellet mill die is 6mm as well as 8mm, and the size of basic materials must be under 5mm, or they may block the holes and also minimize pellet manufacturing.




The adhesive force identifies the forming rate of the pellets Many biomass products include lignin, which would thaw under high temperature and also function as binder. Yet some materials like rice husk has reduced glue pressure. It need to be blended with sawdust or binders to make pellets



The density as well as size of the wood pellets.

The thickness of timber pellets is figured out by the opening dimension of the die. The length is identified by the slicer. In flat die pellet machine, the slicer is set up 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 attain various dimensions. For your own use, it is far better to be short. For transportation and selling, it suggest to be a little lengthy.



After the timber pellets come out from the pellet machine, they are warm with some vapors. They can be dried and cooled in an open area, or by a counter-flow colder. Quick cooling down can improve the firmness of the wood pellets, and help with storage space and also transportation.



Do not close down the machine right after making pellets.

When you finished making pellets, do not shut the pellet machine down at once. Add some combined oil and also biomass materials to the pellet machine as well as allow it compete 1-2 min. By doing this, we can fill up the die holes with oil mixture, to ensure that we can straight start making pellets the next time. With this procedure, we can not just keep the mold and mildew, but additionally conserve time. When the pellet machine stops, loosen the changing screw and remove the left materials.



The upkeep of roller, die, shafts and transmission

You must eliminate all hard things and metal blocks in resources before 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 receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller sustains high pressure during operation. As there is no dirt protector in the pellet machine, so you need to clean up the bearing every 2-5 hours, as well as lube it with oil. After every 8 functioning hrs, the main shaft requirement to be fueled oil. The gearbox demand cleaning every half a year. If there is unusual high warm in the gearbox, you can utilize better gear oil as well as increase the clearance in between the equipments for maintenance. The securing screw in the transmission part also need to be replaced routinely.



How to replace roller and die?

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



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart as well as change it with a brand-new one. If the ring die is taken care of with screws, you need to drink the ring die delicately, as well as eliminate the screw with even toughness.



In level die pellet machine, the flat die is installed with retaining nuts in the keyway. On the 2 sides of the level die, there are two balanced screw openings. pellet making machine price can utilize the screw driver to push them out, or utilize a magnet to pull them out. Throughout your pushing or pulling, maintain the flat die shaking with a hammer, to ensure that the screw will not stuck in the screw opening.



Defense of the drive engine

Select the matched power according to the needed production. If the power is insufficient, the production will certainly be reduced as well as the pelletizing effect is poor. If richi pellet machine is as well huge, it will eat even more power, accelerate the weariness, and shorten the service life of roller as well as die.



The examination as well as repair work should be performed in power off condition. The machine ought to be put near the functioning location, so regarding lower the relocating time as high as possible. Shield it from water logging, rainfall, electric leak, fire, and so on.



Just when we use the pellet machine correctly and keep it frequently can we maximize the pellet machine and prolong its working life.
