How to use as well as keep wood pellet machine properly?<br>
Grinding prior to making use of

A lot of roller and level dies in pellet machine are refined by high-heat therapy. After planing, exploration, milling, as well as relieving process, there are generally lots of cloths inside the die openings, which might affect the pelletizing effects and manufacturing. For that reason, before starting a brand-new pellet machine, or after changing a brand-new die, you require to grind it completely.



We make use of oil mix to process grind the roller as well as level die. The oil mixture is composed of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you must adjust the clearance between roller and also level die to 0.1-0.3 mm. The grinding process needs to last 15-40 min.



For ring die pellet mill, the grinding procedure calls for more oil blend and longer time. The quantity of oil mix is 10% that of pellet manufacturing per hr. The grinding time is 30-50 min. And also the clearance in between ring die and the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The ideal moisture web content of biomass materials need to between 14% and 20%. Dry products are hard to take shape, moist materials will make the pellets loose. The dimension of the raw materials ought to be less than the hole size of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm and also 8mm, and the size of basic materials should be under 5mm, or they may obstruct the holes and minimize pellet production.




The sticky pressure establishes the developing rate of the pellets Most biomass products contain lignin, which would certainly thaw under high temperature and also work as binder. But some materials like rice husk has low glue force. It need to be combined with sawdust or binders to make pellets



The density and also size of the wood pellets.

The density of wood pellets is established by the hole dimension of the die. The length is figured out by the slicer. In flat 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 different sizes. For fertilizer pellet machine , it is better to be short. For transport as well as selling, it advise to be a little lengthy.



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



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

When you completed making pellets, do not close the pellet machine down at the same time. Include some blended oil as well as biomass products to the pellet machine as well as allow it compete 1-2 minutes. By doing small wood pellet mill for sale , we can load the die holes with oil combination, so that we can directly begin making pellets the following time. With this procedure, we can not just maintain the mold and mildew, however also save time. When the pellet machine stops, loosen up the adjusting screw and eliminate the left materials.



The maintenance of roller, die, shafts as well as transmission


You should eliminate all difficult items and steel blocks in raw materials before feeding them into the pellet machine, or they would certainly create damage to the roller, die or major shaft. You can mount a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can reach up to 80 ℃, and the roller maintains high pressure throughout procedure. As there is no dust guard in the pellet machine, so you require to clean up the bearing every 2-5 hours, and also oil it with oil. After every 8 functioning hours, the primary shaft requirement to be oiled. The gearbox demand cleaning every half a year. If there is abnormal high heat in the gearbox, you can utilize far better gear oil and also boost the clearance between the equipments for maintenance. The fastening screw in the transmission component additionally require to be changed on a regular basis.



Exactly how to replace roller as well as die?

When the rollers breaks, you can change the roller covering or the entire set of roller. If the bearing obtain loosened or locked, you need to replace the bearing and 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 fixed with screws, you require to drink the ring die carefully, and get rid of the screw with even toughness.



In flat die pellet machine, the level die is set up with keeping nuts in the keyway. On the 2 sides of the level die, there are two balanced screw openings. You can utilize the screw motorist to press them out, or utilize a magnet to draw them out. During your pushing or pulling, maintain the level die vibrating with a hammer, to ensure that the screw won't stuck in the screw opening.



Protection of the drive engine

Pick the matched power according to the required manufacturing. If the power is not nearly enough, the manufacturing will certainly be reduced as well as the pelletizing result is poor. If the power is as well big, it will eat more power, accelerate the weariness, and also reduce the service life of roller and also die.



The examination and repair service must be accomplished in power off problem. The machine ought to be positioned near the working place, so regarding lower the moving time as long as feasible. Protect it from water logging, rain, electric leakage, fire, and so on.



Only when we use the pellet machine effectively and keep it regularly can we maximize the pellet machine as well as prolong its working life.
