Just how to use and keep wood pellet machine correctly?<br>
Grinding before utilizing

Most roller as well as level dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, as well as relieving process, there are generally lots of cloths inside the die openings, which might affect the pelletizing effects and production. Consequently, before beginning a brand-new pellet machine, or after changing a brand-new die, you need to grind it extensively.



We make use of oil mixture to refine grind the roller as well as level die. The oil blend is composed of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding the oil blend to the pellet machine, you need to change the clearance in between roller as well as level 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 even more oil mix and longer time. The amount of oil mixture is 10% that of pellet production per hour. The grinding time is 30-50 minutes. And also the clearance in between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of resources

The suitable wetness web content of biomass products must in between 14% as well as 20%. Dry materials are upsetting shape, wet materials will certainly make the pellets loose. The size of the raw products need to be less than the hole size of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm and also 8mm, and the dimension of raw materials ought to be under 5mm, or they may obstruct the holes as well as lower pellet manufacturing.



The sticky pressure figures out the creating rate of the pellets The majority of biomass products consist of lignin, which would certainly melt under heat and also act as binder. But some materials like rice husk has reduced sticky force. It require to be blended with sawdust or binders to make pellets



The thickness and also length of the wood pellets.

The thickness of timber pellets is identified by the opening dimension of the die. The length is figured out by the slicer. In richi pellet mill , 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 different dimensions. For your own use, it is much better to be brief. For transport and also marketing, it advise to be a little lengthy.



After the wood pellets appear from the pellet machine, they are warm with some vapors. They can be dried out as well as cooled in an open area, or by a counter-flow colder. Quick cooling can boost the firmness of the timber pellets, as well as facilitate storage as well as transport.




Do not shut down the machine right after making pellets.

When you ended up making pellets, do not shut the pellet machine down simultaneously. Add some combined oil and also biomass products to the pellet machine and allow it run for 1-2 minutes. This way, we can load the die holes with oil combination, so that we can straight start making pellets the following time. With this process, we can not just keep the mold and mildew, yet additionally save time. When the pellet machine quits, loosen up the readjusting screw and also clear away the left products.



The maintenance of roller, die, shafts and also transmission

You should eliminate all tough things and metal blocks in resources prior to feeding them into the pellet machine, or they would trigger damage to the roller, die or primary shaft. You can mount a tubular magnet on the feed receptacle.




The warmth inside the pelletizing chamber can reach up to 80 ℃, as well as the roller sustains high pressure throughout operation. As there is no dirt protector in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and lubricate it with oil. After every 8 functioning hours, the primary shaft need to be oiled. The transmission demand cleaning every half a year. If there is unusual high heat in the transmission, you can utilize much better gear oil as well as enhance the clearance between the gears for upkeep. The attaching screw in the transmission component also require to be replaced on a regular basis.



Exactly how to replace roller and also die?

When the rollers breaks, you can change the roller shell or the whole set of roller. If the bearing obtain loosened or locked, you need to replace 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 and change it with a brand-new one. If the ring die is taken care of with screws, you need to shake the ring die delicately, as well as remove the screw with also strength.



In level die pellet machine, the level die is installed with keeping nuts in the keyway. On cattle feed pellet machine of the flat die, there are 2 balanced screw holes. You can utilize the screw driver to push them out, or make use of a magnet to draw them out. During your pushing or drawing, keep the level die shaking with a hammer, to make sure that the screw will not stuck in the screw hole.



Defense of the drive engine

Pick the matched power according to the necessary manufacturing. If the power is inadequate, the production will be low and the pelletizing impact is poor. If the power is as well large, it will eat even more power, accelerate the weariness, as well as shorten the life span of roller as well as die.



The test and repair service should be performed in power off condition. The machine must be positioned near the functioning area, so as to decrease the relocating time as long as feasible. Safeguard it from water logging, rainfall, electrical leak, fire, and so on.



Just when we make use of the pellet machine appropriately and keep it frequently can we take full advantages of the pellet machine and extend its working life.
