How to use and maintain wood pellet machine properly
How to use and preserve timber pellet machine effectively?
Grinding before using
A lot of roller and level dies in pellet machine are refined by high-heat therapy. After planing, boring, milling, as well as appeasing process, there are typically numerous cloths inside the die holes, which may affect the pelletizing effects and also production. Consequently, before beginning a brand-new pellet machine, or after replacing a brand-new die, you require to grind it extensively.

We make use of oil combination to process grind the roller and also flat die. The oil blend 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 ought to change 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 calls for even more oil mixture and also longer time. The quantity of oil mix is 10% that of pellet production per hr. The grinding time is 30-50 minutes. As well as the clearance between ring die and also the roller is 0.1-0.4 mm.

Pretreatment of basic materials
The ideal moisture material of biomass products ought to between 14% as well as 20%. Dry products are hard to take form, wet materials will certainly make the pellets loose. The size of the raw products must be less than the hole dimension of pellet mill dies. Typically, the hole size of the pellet mill die is 6mm as well as 8mm, as well as the dimension of raw materials need to be under 5mm, or they may block the holes and also minimize pellet production.

The adhesive force establishes the forming price of the pellets Many biomass products contain lignin, which would melt under high temperature as well as act as binder. However some products like rice husk has low adhesive pressure. olx pellet machine require to be mixed with sawdust or binders to make pellets


The density and size of the timber pellets.
The thickness of wood pellets is figured out by the hole size of the die. The length is figured out 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 set up outside the ring die. Both of them can be adjusted to accomplish different sizes. For your very own use, it is far better to be short. For transportation as well as marketing, it advise to be a little long.

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

Do not close down the machine right after making pellets.
When you finished making pellets, don't shut the pellet machine down simultaneously. Add some mixed oil and also biomass materials to the pellet machine as well as let it run for 1-2 min. This way, we can load the die openings with oil mixture, to ensure that we can directly start making pellets the next time. With this procedure, we can not just maintain the mold and mildew, however likewise save time. When the pellet machine stops, loosen the readjusting screw as well as remove the left products.

The upkeep of roller, die, shafts as well as gearbox
You need to eliminate all tough objects and also steel blocks in resources before feeding them into the pellet machine, or they would certainly cause damages to the roller, die or primary shaft. You can set up a tubular magnet on the feed receptacle.

The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure throughout procedure. As there is no dust protector in the pellet machine, so you require to tidy up the bearing every 2-5 hrs, and lube it with oil. After every 8 working hours, the main shaft requirement to be oiled. The transmission requirement cleaning every half a year. If there is irregular high warm in the transmission, you can make use of far better gear oil and enhance the clearance between the equipments for upkeep. The fastening screw in the transmission component also require to be replaced consistently.

Exactly how to change roller as well as die?
When the rollers wears out, you can change the roller covering or the whole set of roller. If the bearing get loosened or locked, you require to change the bearing and also even the shaft.

In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart and also change it with a new one. If the ring die is fixed with screws, you need to shake the ring die gently, and remove the screw with even toughness.

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 in proportion screw openings. You can make use of the screw driver to push them out, or utilize a magnet to draw them out. Throughout your pressing or pulling, maintain the flat die shaking with a hammer, to ensure that the screw will not stuck in the screw opening.

Protection of the drive engine
Choose the matched power according to the necessary manufacturing. If the power is not nearly enough, the manufacturing will certainly be reduced and the pelletizing effect is poor. If the power is too huge, it will certainly eat even more power, accelerate the exhaustion, and reduce the life span of roller as well as die.

manure pelletizer and repair work should be performed in power off problem. The machine should be placed near the working area, so regarding reduce the moving time as much as feasible. Secure it from water logging, rainfall, electric leakage, fire, and so on.

Just when we utilize the pellet machine effectively and also preserve it routinely can we take full advantages of the pellet machine and extend its working life.
