Exactly how to make use of and preserve wood pellet machine effectively?<br>


Grinding before using

Most roller and also flat dies in pellet machine are processed by high-heat therapy. After planing, drilling, milling, as well as appeasing procedure, there are normally many cloths inside the die holes, which may influence the pelletizing impacts as well as manufacturing. Consequently, prior to beginning a brand-new pellet machine, or after changing a new die, you require to grind it thoroughly.



We make use of oil mixture to process grind the roller and also level die.hay pellet mill for saleis composed of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you should change the clearance in between roller and also flat die to 0.1-0.3 mm. The grinding process should last 15-40 min.



For ring die pellet mill, the grinding procedure requires even more oil blend as well as longer time. The amount of oil blend is 10% that of pellet production per hr. The grinding time is 30-50 min. As well as the clearance between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of raw materials

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



The glue pressure determines the forming rate of the pellets A lot of biomass products include lignin, which would certainly melt under high temperature as well as serve as binder. Yet some materials like rice husk has low adhesive force. It require to be blended with sawdust or binders to make pellets




The density as well as length of the timber pellets.

The density of timber pellets is identified by the hole dimension of the die. The size is determined by the slicer. In level die pellet machine, the slicer is mounted under the level die, while in ring die pellet machine, the slicer is set up outside the ring die. Both of them can be adapted to accomplish various sizes. For your own usage, it is much better to be brief. For transportation and marketing, it advise to be a little long.



After the wood pellets come out from the pellet machine, they are warm with some steams. They can be dried out as well as cooled down in an open field, or by a counter-flow cooler. Quick cooling can boost the solidity of the timber pellets, and promote storage as well as transport.



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

When you ended up making pellets, don't close the pellet machine down simultaneously. Add some blended oil and also biomass products to the pellet machine and let it compete 1-2 min. This way, we can load the die openings with oil mix, so that we can directly start making pellets the next time. With this process, we can not only keep the mold, but likewise save time. When the pellet machine stops, loosen the readjusting screw and eliminate the left materials.



The upkeep of roller, die, shafts and gearbox

You must remove all hard things and also steel blocks in resources before feeding them right into the pellet machine, or they would certainly trigger damage to the roller, die or primary shaft. You can set up a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can rise to 80 , as well as the roller sustains high pressure throughout procedure. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, and oil it with oil. Afterpellet making dieworking hrs, the main shaft need to be oiled. The gearbox need cleansing every half a year. If there is uncommon high warm in the gearbox, you can utilize better equipment oil and boost the clearance between the equipments for upkeep.richi pellet machineattaching screw in the transmission component additionally require to be changed routinely.



Exactly how to change roller and die?

When the rollers breaks, you can replace the roller covering or the whole collection of roller. If the bearing get loosened or secured, you require to change the bearing as well as even the shaft.



In ring die pellet machine, just loosen up the hoop chuck, take the old ring die apart as well as replace it with a brand-new one. If the ring die is fixed with screws, you require to shake the ring die delicately, as well as remove the screw with even toughness.



In flat die pellet machine, the level die is installed with maintaining nuts in the keyway. On the 2 sides of the flat die, there are 2 symmetrical screw holes. You can make use of the screw motorist to press them out, or utilize a magnet to draw them out. During your pressing or pulling, maintain the flat die vibrating with a hammer, to ensure that the screw will not stuck in the screw hole.



Protection of the drive engine

Select the matched power according to the needed production. If the power is insufficient, the manufacturing will be low as well as the pelletizing effect is poor. If the power is too large, it will certainly take in more power, accelerate the weariness, as well as shorten the life span of roller and die.



The exam and also repair work ought to be accomplished in power off problem. The machine should be put near the working area, so as to minimize the moving time as long as possible. Safeguard it from water logging, rain, electric leakage, fire, etc.




Only when we make use of the pellet machine properly as well as preserve it regularly can we take full advantages of the pellet machine and also lengthen its working life.
