How to use and maintain wood pellet machine properly
Just how to utilize as well as keep wood pellet machine correctly?
Grinding prior to making use of
The majority of roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, as well as relieving procedure, there are normally many dustcloths inside the die openings, which might influence the pelletizing effects as well as production. Consequently, before beginning a brand-new pellet machine, or after changing a brand-new die, you require to grind it completely.

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

For ring die pellet mill, the grinding process requires even more oil blend as well as longer time. The amount of oil mix is 10% that of pellet manufacturing per hr. The grinding time is 30-50 minutes. As well as diy feed pellet machine between ring die as well as the roller is 0.1-0.4 mm.

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

The adhesive pressure figures out the developing price of the pellets The majority of biomass materials have lignin, which would melt under heat as well as act as binder. But some materials like rice husk has low glue pressure. It require to be blended with sawdust or binders to make pellets

The density as well as size of the timber pellets.
The density of wood pellets is identified by the hole dimension of the die. The length is figured out 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 set up outside the ring die. Both of them can be adjusted to achieve different dimensions. For your very own usage, it is better to be short. For transportation and marketing, it suggest to be a little long.

After the timber pellets appear from the pellet machine, they are hot with some vapors. They can be dried and also cooled down in an open area, or by a counter-flow cooler. Quick cooling down can improve the solidity of the timber pellets, as well as assist in storage and also transportation.

Do not shut down the machine right after making pellets.
When you ended up making pellets, don't shut the pellet machine down at once. Add some mixed oil as well as biomass products to the pellet machine and also allow it run for 1-2 min. By doing this, we can load the die openings with oil mixture, so that we can straight start making pellets the next time. With this process, we can not only keep the mold and mildew, however also conserve time. When electric pellet mill , loosen up the readjusting screw as well as remove the left materials.

The upkeep of roller, die, shafts and gearbox
You must get rid of all tough objects and also metal blocks in raw materials prior to feeding them right into the pellet machine, or they would certainly trigger damage 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 also the roller maintains high pressure throughout procedure. As there is no dirt guard in the pellet machine, so you need to clean up the bearing every 2-5 hrs, as well as lube it with oil. After every 8 working hours, the primary shaft need to be oiled. The gearbox demand cleaning every half a year. If there is uncommon high heat in the transmission, you can make use of much better gear oil and also raise the clearance in between the gears for upkeep. The securing screw in the transmission part likewise require to be replaced consistently.


Just how to replace roller and die?
When the rollers wears out, you can change the roller shell or the entire collection of roller. If the bearing obtain loose or secured, you need to replace the bearing as well as also the shaft.

In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and change it with a new one. If the ring die is taken care of with screws, you require to shake the ring die delicately, and also get rid of the screw with even stamina.


In level die pellet machine, the flat die is mounted with maintaining nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw openings. You can use the screw chauffeur to press them out, or utilize a magnet to draw them out. During your pressing or drawing, maintain the level die shaking with a hammer, to ensure that the screw will not embeded the screw hole.

Security of the drive engine
Pick the matched power according to the necessary production. If the power is inadequate, the production will certainly be low and the pelletizing effect is poor. If the power is as well large, it will eat even more power, increase the weariness, and shorten the service life of roller as well as die.

The test as well as fixing must be performed in power off problem. The machine should be placed near the functioning location, so regarding minimize the moving time as long as feasible. Safeguard it from water logging, rain, electric leakage, fire, and so on.

Only when we make use of the pellet machine appropriately as well as maintain it routinely can we take full advantages of the pellet machine as well as lengthen its functioning life.
