Just how to use as well as maintain wood pellet machine correctly?<br>
Grinding before using

A lot of roller as well as flat dies in pellet machine are refined by high-heat treatment. After planing, exploration, milling, and quenching process, there are typically numerous rags inside the die openings, which may affect the pelletizing impacts as well as manufacturing. Consequently, prior to beginning fish feed machine for sale , or after changing a brand-new die, you require to grind it completely.




We use oil mixture to refine grind the roller as well as flat die. The oil mixture is made up of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding the oil combination 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 even more oil mixture as well as longer time. The amount of oil mixture is 10% that of pellet manufacturing per hr. The grinding time is 30-50 minutes. As well as the clearance between ring die and the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The ideal wetness material of biomass products ought to in between 14% as well as 20%. Dry products are upsetting form, damp products will certainly make the pellets loose. The dimension of the raw materials should be less than the hole dimension of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm as well as 8mm, as well as the dimension of resources must be under 5mm, or they might block the holes and reduce pellet manufacturing.



The adhesive force figures out the developing price of the pellets Many biomass products consist of lignin, which would certainly thaw under heat and also work as binder. Yet some materials like rice husk has reduced glue pressure. It require to be combined with sawdust or binders to make pellets



The thickness and also size of the wood pellets.

The density of timber pellets is identified by the opening size of the die. The size is figured out by the slicer. In flat die pellet machine, the slicer is set up under the level die, while in ring die pellet machine, the slicer is set up outside the ring die. Both of them can be gotten used to attain different sizes. For your own use, it is better to be short. For transport and also marketing, it suggest to be a little lengthy.



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



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

When you finished making pellets, do not shut the pellet machine down at once. Add some mixed oil and biomass products to the pellet machine and also let it run for 1-2 min. This way, we can fill the die openings with oil mix, to ensure that we can straight start making pellets the next time. With this process, we can not only maintain the mold and mildew, yet additionally save time. When the pellet machine stops, loosen up the adjusting screw and remove the left materials.



The maintenance of roller, die, shafts and gearbox

You need to remove all hard things and steel blocks in resources before feeding them right into the pellet machine, or they would certainly create damages to the roller, die or main shaft. You can mount a tubular magnet on the feed receptacle.




The warm inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure during procedure. As there is no dirt guard in the pellet machine, so you require to tidy up the bearing every 2-5 hrs, as well as oil it with oil. After every 8 functioning hrs, the main shaft need to be fueled oil. wood pellet extruder cleaning every half a year. If there is abnormal high heat in the transmission, you can utilize better gear oil as well as raise the clearance in between the gears for maintenance. The fastening screw in the transmission component also require to be replaced regularly.



How to change roller and die?

When the rollers breaks, you can change the roller shell or the entire collection of roller. If the bearing obtain loosened or locked, you require to change the bearing as well as even the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and change it with a brand-new one. If the ring die is repaired with screws, you require to tremble the ring die delicately, as well as eliminate the screw with even stamina.



In flat die pellet machine, the level die is set up with retaining nuts in the keyway. On the 2 sides of the flat die, there are 2 in proportion screw holes. You can make use of the screw chauffeur to push them out, or utilize a magnet to draw them out. Throughout your pressing or pulling, keep the level die shaking with a hammer, to make sure that the screw won't stuck in the screw opening.



Defense of the drive engine

Choose the matched power according to the required production. If the power is insufficient, the production will be low and the pelletizing result is poor. If the power is as well big, it will certainly take in even more power, increase the fatigue, as well as shorten the service life of roller as well as die.



The exam as well as repair should be accomplished in power off problem. The machine must be placed near the functioning place, so regarding decrease the moving time as much as possible. Protect it from water logging, rainfall, electrical leakage, fire, and so on.



Just when we utilize the pellet machine appropriately as well as preserve it regularly can we take full advantages of the pellet machine and prolong its working life.
