Just how to make use of and also keep wood pellet machine properly?<br>
Grinding prior to utilizing

Many roller and also level dies in pellet machine are processed by high-heat therapy. After planing, drilling, milling, and satiating procedure, there are typically numerous dustcloths inside the die openings, which may affect the pelletizing results and also production. As a result, prior to starting a brand-new pellet machine, or after replacing a new die, you need to grind it extensively.



We utilize oil combination to process grind the roller and level die. The oil mixture is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil mix to the pellet machine, you need to readjust the clearance between roller and also 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 mix and also longer time. The quantity of oil combination is 10% that of pellet production per hour. The grinding time is 30-50 minutes. And the clearance in between ring die as well as the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The appropriate moisture web content of biomass products ought to between 14% as well as 20%. Dry products are upsetting form, damp products will certainly make the pellets loose. The size of the raw materials ought to be less than the hole size of pellet mill dies. Usually, the hole size of the pellet mill die is 6mm and also 8mm, as well as the dimension of basic materials should be under 5mm, or they might obstruct the holes and also decrease pellet production.



The adhesive pressure figures out the creating price of the pellets Most biomass materials contain lignin, which would certainly melt under high temperature as well as function as binder. But some materials like rice husk has reduced glue force. It require to be blended with sawdust or binders to make pellets



The thickness and length of the wood pellets.

The thickness of wood pellets is determined by the opening size of the die. durable small pellet mill is established 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 installed outside the ring die. Both of them can be adapted to accomplish different dimensions. For your very own usage, it is much better to be brief. For transport and also marketing, it recommend to be a little lengthy.





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



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. Include some mixed oil as well as biomass products to the pellet machine as well as allow it run for 1-2 min. By doing this, we can fill up the die openings with oil mix, to make sure that we can directly start making pellets the following time. With this procedure, we can not just preserve the mold, however additionally save time. When the pellet machine quits, loosen the changing screw as well as clear away the left products.



The maintenance of roller, die, shafts and also gearbox

You need to get rid of all tough objects as well as steel blocks in raw materials prior to feeding them into the pellet machine, or they would trigger damage to the roller, die or major shaft. You can install a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and the roller maintains high pressure during procedure. As there is no dirt protector in the pellet machine, so you require to tidy up the bearing every 2-5 hours, as well as oil it with oil. After every 8 functioning hrs, the main shaft demand to be fueled oil. The transmission requirement cleaning every half a year. If there is unusual high warmth in the transmission, you can make use of far better equipment oil and also enhance the clearance in between the equipments for maintenance. The attaching screw in the transmission part likewise require to be replaced consistently.



Just how to replace roller and also die?

When the rollers wears out, you can change the roller covering or the whole set of roller. If the bearing get loosened or locked, you need to replace 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 brand-new one. If the ring die is repaired with screws, you need to drink the ring die delicately, and also get rid of the screw with even strength.



In flat die pellet machine, the level die is mounted with maintaining nuts in the keyway. On kl230 animal feed of the flat die, there are 2 balanced screw holes. You can utilize the screw chauffeur to push them out, or utilize a magnet to pull them out. During 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

Select the matched power according to the needed production. If the power is inadequate, the manufacturing will certainly be low and the pelletizing result is poor. If the power is also big, it will consume even more power, increase the weariness, and also reduce the life span of roller as well as die.



The exam as well as fixing must be accomplished in power off problem. The machine should be placed near the working place, so regarding reduce the relocating time as high as possible. Protect it from water logging, rainfall, electrical leak, fire, etc.



Only when we use the pellet machine appropriately as well as preserve it regularly can we make the most of the pellet machine and also extend its working life.
