Just how to use and preserve timber pellet machine properly?<br>
Grinding before using

Many roller and also flat dies in pellet machine are refined by high-heat treatment. After planing, drilling, milling, and satiating procedure, there are generally lots of rags inside the die openings, which might influence the pelletizing impacts and also production. Therefore, prior to starting a brand-new pellet machine, or after changing a brand-new die, you need to grind it completely.



We utilize oil blend to refine grind the roller as well as level die. horse feed pellet machine is made up of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you need to adjust the clearance in between roller and 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 more oil mixture as well as longer time. The quantity of oil mixture is 10% that of pellet manufacturing 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 dampness content of biomass products must in between 14% and also 20%. Dry products are upsetting form, wet materials will certainly make the pellets loose. The size of the raw products need to be less than the hole dimension of pellet mill dies. Usually, the hole size of the pellet mill die is 6mm and 8mm, and also the size of basic materials must be under 5mm, or they may obstruct the holes and lower pellet production.



The adhesive pressure figures out the developing rate of the pellets Many biomass materials consist of lignin, which would melt under heat and serve as binder. Yet some products like rice husk has low glue force. It require to be blended with sawdust or binders to make pellets



The density and length of the timber pellets.

The density of wood pellets is determined by the hole dimension of the die. The length is figured out 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 mounted outside the ring die. Both of them can be adjusted to achieve different sizes. For your own usage, it is far better to be brief. For transport as well as marketing, it suggest to be a little long.



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



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

When you completed making pellets, do not close the pellet machine down at the same time. Add some mixed oil and biomass materials to the pellet machine and allow it compete 1-2 min. This way, we can load the die openings with oil mix, to make sure that we can straight begin making pellets the next time. With this process, we can not just preserve the mold, yet likewise save time. When the pellet machine stops, loosen up the adjusting screw as well as eliminate the left materials.



The upkeep of roller, die, shafts as well as gearbox


You need to get rid of all difficult things and also metal blocks in resources prior to feeding them into the pellet machine, or they would certainly trigger damages to the roller, die or major shaft. You can set up a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can reach up to 80 ℃, and the roller sustains high pressure throughout operation. As there is no dust protector 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 hrs, the major shaft need to be fueled oil. The transmission demand cleansing every half a year. If there is abnormal high warmth in the gearbox, you can utilize much better equipment oil as well as enhance the clearance between the gears for maintenance. The securing screw in the transmission part likewise require to be changed on a regular basis.



How to change roller and also die?

When the rollers wears out, you can replace the roller covering or the whole set of roller. If the bearing obtain loose or locked, you require to change the bearing and also even the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and replace it with a new one. If the ring die is taken care of with screws, you require to drink the ring die delicately, and also eliminate the screw with also toughness.



In flat die pellet machine, the level die is mounted with maintaining nuts in the keyway. On the 2 sides of the flat die, there are 2 symmetrical screw openings. You can use the screw chauffeur to press them out, or make use of a magnet to pull them out. Throughout your pushing or drawing, keep the level die shaking with a hammer, to ensure that the screw won't stuck in the screw hole.



Defense of the drive engine

Select the matched power according to the needed production. If the power is not enough, the production will certainly be low and also the pelletizing result is poor. If goat feed making machine is as well large, it will consume more power, increase the exhaustion, and also shorten the life span of roller as well as die.



The test as well as repair work must be executed in power off condition. The machine must be placed near the working area, so regarding reduce the relocating time as high as possible. Shield it from water logging, rainfall, electrical leakage, fire, etc.



Only when we make use of the pellet machine effectively and maintain it consistently can we take full advantages of the pellet machine and extend its functioning life.
