Exactly how to utilize as well as maintain wood pellet machine correctly?<br>
Grinding prior to utilizing

The majority of roller and also flat dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, and satiating process, there are generally several rags inside the die holes, which might affect the pelletizing impacts as well as production. Consequently, prior to starting a brand-new pellet machine, or after changing a new die, you need to grind it completely.



We utilize oil blend to process grind the roller and level die. The oil blend is composed of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil blend to the pellet machine, you need to adjust the clearance between roller and also level die to 0.1-0.3 mm. The grinding procedure should last 15-40 min.




For ring die pellet mill, the grinding procedure requires more oil mix and longer time. The amount of oil combination is 10% that of pellet production per hour. chicken pellet making machine grinding time is 30-50 min. And also the clearance between ring die as well as the roller is 0.1-0.4 mm.




Pretreatment of basic materials

The ideal wetness material of biomass materials should between 14% and also 20%. Dry products are upsetting shape, damp products will make the pellets loose. The size of the raw products should be less than the hole size of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm and 8mm, and the size of raw materials need to be under 5mm, or they might obstruct the holes and also decrease pellet production.



The glue pressure figures out the forming rate of the pellets A lot of biomass products consist of lignin, which would certainly melt under high temperature and also function as binder. However some products like rice husk has reduced sticky pressure. It require to be mixed with sawdust or binders to make pellets



The density and size of the wood pellets.

The density of wood pellets is figured out by the hole size of the die. The length is identified by the slicer. In level die pellet machine, the slicer is set up under the flat die, while in ring die pellet machine, the slicer is installed outside the ring die. Both of them can be gotten used to achieve different sizes. For your own usage, it is much better to be short. For transportation and marketing, it advise to be a little lengthy.



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



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

When you finished making pellets, do not shut the pellet machine down simultaneously. Include some combined oil and biomass materials to the pellet machine as well as let it compete 1-2 min. This way, we can fill up the die holes with oil mixture, to ensure that we can straight start making pellets the next time. With this procedure, we can not only maintain the mold, yet likewise conserve time. When the pellet machine stops, loosen up the readjusting screw as well as eliminate the left products.



The upkeep of roller, die, shafts and transmission

You should remove all hard objects and also metal blocks in resources prior to feeding them right into the pellet machine, or they would certainly cause damages to the roller, die or main 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 during procedure. As there is no dust guard in the pellet machine, so you require to clean up the bearing every 2-5 hrs, as well as lubricate it with oil. After every 8 functioning hours, the major shaft demand to be oiled. The transmission need cleansing every half a year. If there is abnormal high warm in the gearbox, you can utilize far better gear oil and also increase the clearance in between the gears for maintenance. The fastening screw in the transmission part additionally require to be changed regularly.



How to replace roller as well as die?

When the rollers wears out, you can replace the roller shell or the whole collection of roller. If the bearing get loosened or secured, you need to replace the bearing and also the shaft.



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



In flat die pellet machine, the level die is installed with keeping nuts in the keyway. On the 2 sides of the level die, there are two in proportion screw holes. You can use the screw vehicle driver to press them out, or utilize a magnet to pull them out. During your pushing or pulling, keep the flat die vibrating with a hammer, to ensure that the screw will not embeded the screw hole.



Protection of the drive engine

Pick the matched power according to the needed manufacturing. If the power is insufficient, the manufacturing will certainly be reduced and the pelletizing result is poor. If the power is as well large, it will take in more power, accelerate the weariness, and reduce the life span of roller and also die.



The examination as well as repair work must be executed in power off condition. The machine must be placed near the functioning place, so as to lower the moving time as long as feasible. Safeguard it from water logging, rainfall, electrical leakage, fire, and so on.



Just when we make use of the pellet machine effectively as well as maintain it on a regular basis can we make the most of the pellet machine and lengthen its functioning life.
