How to make use of and preserve wood pellet machine effectively?<br>
Grinding prior to using

Most roller and also flat dies in pellet machine are refined by high-heat therapy. After planing, exploration, milling, and also satiating process, there are normally many cloths inside the die holes, which may affect the pelletizing impacts as well as manufacturing. As a result, before starting a brand-new pellet machine, or after replacing a new die, you need to grind it extensively.



We use oil blend to refine grind the roller and level die. The oil mixture is made up of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mixture to the pellet machine, you need to change the clearance in between roller as well as flat die to 0.1-0.3 mm. The grinding procedure needs to last 15-40 minutes.



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



Pretreatment of resources

The ideal dampness material of biomass materials ought to between 14% as well as 20%. Dry materials are upsetting form, wet products will make the pellets loose. sawdust pellet press machine of the raw materials ought to be less than the hole size of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm as well as 8mm, and the size of basic materials ought to be under 5mm, or they might block the holes as well as lower pellet manufacturing.




The adhesive pressure determines the developing rate of the pellets Many biomass products have lignin, which would certainly melt under high temperature and act as binder. But wood pellet making machine like rice husk has reduced sticky force. It require to be blended with sawdust or binders to make pellets



The thickness and also size of the wood pellets.

The thickness of timber 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 set up outside the ring die. Both of them can be gotten used to attain various sizes. For your own use, it is better to be brief. For transportation and selling, it suggest to be a little long.



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



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


When you completed making pellets, do not shut the pellet machine down at the same time. Include some combined oil and biomass products to the pellet machine and allow it compete 1-2 min. This way, we can load the die openings with oil combination, to ensure that we can straight start making pellets the following time. With this procedure, we can not just keep the mold and mildew, however likewise conserve time. When the pellet machine stops, loosen the readjusting screw and clear away the left products.



The upkeep of roller, die, shafts and also transmission

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



The warmth inside the pelletizing chamber can rise to 80 ℃, and the roller sustains high pressure during operation. As there is no dust guard in the pellet machine, so you need to clean up the bearing every 2-5 hrs, and oil it with oil. After every 8 working hrs, the main shaft need to be fueled oil. The transmission need cleaning every half a year. If there is irregular high warmth in the gearbox, you can utilize much better equipment oil as well as enhance the clearance in between the gears for upkeep. The attaching screw in the transmission part additionally require to be replaced on a regular basis.



How to replace roller as well as die?

When the rollers wears, you can replace the roller covering or the entire set of roller. If the bearing get loosened or secured, you need to change the bearing and also the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart as well as replace it with a new one. If the ring die is taken care of with screws, you need to drink the ring die gently, and also get rid of the screw with also strength.



In flat die pellet machine, the level die is set up with preserving nuts in the keyway. On the 2 sides of the level die, there are two symmetrical screw openings. You can utilize the screw vehicle driver to push them out, or utilize a magnet to draw them out. Throughout your pressing or pulling, maintain the level die vibrating with a hammer, to make sure that the screw won't stuck in the screw hole.



Security of the drive engine

Select the matched power according to the required manufacturing. If the power is inadequate, the production will be reduced and the pelletizing result is poor. If richi pellet mill is too large, it will consume more power, accelerate the exhaustion, and shorten the life span of roller and die.



The test and also repair work need to be accomplished in power off problem. The machine must be positioned near the functioning location, so regarding decrease the relocating time as much as feasible. Secure it from water logging, rainfall, electrical leakage, fire, etc.



Just when we make use of the pellet machine properly as well as keep it on a regular basis can we make the most of the pellet machine and also prolong its functioning life.
