Just how to make use of as well as preserve timber pellet machine properly?<br>
Grinding before making use of

Most roller and also flat dies in pellet machine are refined by high-heat therapy. After planing, boring, milling, and satiating process, there are generally several rags inside the die openings, which may affect the pelletizing results and production. Therefore, before starting a new pellet machine, or after replacing a brand-new die, you require to grind it thoroughly.



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



For ring die pellet mill, the grinding procedure requires more oil mix as well as longer time. The quantity of oil blend is 10% that of pellet production 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 appropriate wetness web content of biomass products ought to in between 14% as well as 20%. Dry products are hard to take shape, moist materials will make the pellets loose. The size of the raw materials ought to be less than the hole size of pellet mill dies. Normally, the hole size of the pellet mill die is 6mm and also 8mm, as well as the size of basic materials must be under 5mm, or they may obstruct the holes and reduce pellet production.



The sticky pressure establishes the developing rate of the pellets Many biomass products consist of lignin, which would thaw under high temperature and act as binder. Yet some products like rice husk has reduced adhesive pressure. It need to be blended with sawdust or binders to make pellets



The thickness and size of the wood pellets.

The thickness of timber pellets is established by the opening size of the die. The size is determined 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 adjusted to achieve different sizes. For press pellet machine , it is better to be brief. For transportation and marketing, it advise to be a little lengthy.



After the timber pellets come out from the pellet machine, they are hot with some steams. They can be dried out as well as cooled in an open field, or by a counter-flow colder. Quick cooling can boost diy wood pellet machine of the wood pellets, as well as help with storage and transportation.



Do not shut down the machine right after making pellets.

When you ended up making pellets, don't close the pellet machine down at the same time. Include some blended oil and biomass products to the pellet machine and also let it run for 1-2 min. In this way, we can fill the die openings with oil combination, to ensure that we can directly begin making pellets the following time. With this process, we can not just preserve the mold and mildew, however additionally conserve time. When the pellet machine quits, loosen up the readjusting screw as well as clear away the left materials.



The maintenance of roller, die, shafts and also gearbox

You ought to eliminate all tough items and also steel blocks in raw materials prior to feeding them right into the pellet machine, or they would certainly create damages to the roller, die or major shaft. You can set up a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can reach up to 80 ℃, and the roller maintains high pressure during procedure. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, and lubricate it with oil. After every 8 working hrs, the primary shaft demand to be oiled. The transmission requirement cleaning every half a year. If there is unusual high warmth in the gearbox, you can use far better equipment oil as well as increase the clearance between the equipments for upkeep. The attaching screw in the transmission part additionally need to be changed on a regular basis.



Exactly how to replace roller and die?

When the rollers wears, you can replace the roller covering or the entire collection of roller. If the bearing get loose or secured, you require to change the bearing and also the shaft.



In ring die pellet machine, simply loosen 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 shake the ring die gently, and also eliminate the screw with even stamina.



In level die pellet machine, the flat die is set up with preserving nuts in the keyway. On the 2 sides of the level die, there are two balanced screw openings. You can use the screw driver to press them out, or utilize a magnet to pull them out. Throughout your pushing or drawing, maintain the flat die shaking with a hammer, to ensure that the screw will not stuck in the screw hole.




Security of the drive engine

Pick the matched power according to the needed manufacturing. If the power is insufficient, the manufacturing will be low and the pelletizing impact is poor. If the power is too big, it will eat even more power, speed up the fatigue, and reduce the life span of roller and also die.



The test and also fixing ought to be executed in power off condition. The machine ought to be placed near the working place, so regarding decrease the relocating time as much as possible. Safeguard it from water logging, rain, electrical leakage, fire, and so on.




Just when we use the pellet machine correctly and keep it on a regular basis can we maximize the pellet machine as well as lengthen its working life.
