Just how to use and maintain timber pellet machine appropriately?<br>
Grinding prior to utilizing

The majority of roller and also flat dies in pellet machine are refined by high-heat treatment. After planing, exploration, milling, as well as relieving procedure, there are usually lots of rags inside the die holes, which may influence the pelletizing impacts and also production. Therefore, before starting a new pellet machine, or after changing a brand-new die, you require to grind it thoroughly.



We use oil mixture to refine grind the roller and level die. The oil mixture is composed of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you must change the clearance between roller and also level die to 0.1-0.3 mm. The grinding process must last 15-40 minutes.



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



Pretreatment of resources

The appropriate moisture material of biomass products ought to between 14% and 20%. Dry products are upsetting shape, damp materials will make the pellets loose. The dimension of the raw materials ought to be less than the hole dimension of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm and 8mm, as well as the size of basic materials need to be under 5mm, or they might block the holes as well as minimize pellet manufacturing.




The sticky pressure figures out the creating price of the pellets The majority of biomass materials contain lignin, which would thaw under high temperature as well as serve as binder. However some products like rice husk has low glue pressure. It require to be mixed with sawdust or binders to make pellets



The density and length of the wood pellets.

The density of wood pellets is figured out by the hole size of the die. The length is established by the slicer. In flat die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is installed outside the ring die. Both of them can be adjusted to attain different dimensions. For pelletizing machine for plastic recycling , it is better to be brief. For transportation and also marketing, it suggest to be a little lengthy.



After the wood pellets appear from the pellet machine, they are warm with some steams. They can be dried as well as cooled down in an open field, or by a counter-flow colder. Quick cooling down can enhance the solidity of the wood pellets, and also facilitate storage space and transport.



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

When you completed making pellets, do not close the pellet machine down simultaneously. Include some blended oil and biomass materials to the pellet machine as well as allow it run for 1-2 min. In this way, we can load the die holes with oil blend, to ensure that we can straight start making pellets the next time. With this procedure, we can not only maintain the mold and mildew, however additionally save time. When the pellet machine quits, loosen up the readjusting screw and also remove the left products.



The upkeep of roller, die, shafts and also gearbox

You must remove all tough objects as well as steel blocks in raw materials before feeding them into the pellet machine, or they would trigger damages to the roller, die or primary shaft. Richi machine can install a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can rise to 80 ℃, as well as the roller sustains high pressure throughout procedure. As there is no dust guard in the pellet machine, so you need to tidy up the bearing every 2-5 hrs, and also oil it with oil. After every 8 functioning hrs, the major shaft demand to be oiled. The transmission demand cleaning every half a year. If there is unusual high heat in the transmission, you can use better gear oil and also increase the clearance between the gears for upkeep. The attaching screw in the transmission part also require to be replaced regularly.




How to replace roller and die?

When the rollers wears, you can replace the roller shell or the whole set of roller. If the bearing get loose or secured, you need to change 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 taken care of with screws, you need to shake the ring die gently, and also eliminate the screw with even strength.



In level die pellet machine, the level die is installed with maintaining nuts in the keyway. On the 2 sides of the level die, there are two balanced screw openings. You can use the screw motorist to push them out, or make use of a magnet to draw them out. During your pressing or pulling, keep the level die shaking with a hammer, to make sure that the screw won't stuck in the screw hole.



Defense of the drive engine

Pick the matched power according to the required manufacturing. If the power is insufficient, the manufacturing will certainly be low and the pelletizing effect is poor. If the power is too big, it will consume even more power, increase the exhaustion, as well as reduce the service life of roller as well as die.



The exam and also repair ought to be performed in power off condition. The machine must be placed near the working place, so regarding lower the moving time as high as feasible. Protect it from water logging, rainfall, electric leakage, fire, and so on.



Only when we make use of the pellet machine effectively and also maintain it on a regular basis can we make the most of the pellet machine as well as lengthen its functioning life.
