How to use and maintain wood pellet machine properly?<br>
Grinding before utilizing

Many roller and also flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, and satiating procedure, there are normally lots of dustcloths inside the die holes, which might influence the pelletizing impacts and manufacturing. Consequently, prior to starting a brand-new pellet machine, or after replacing a new die, you require to grind it thoroughly.



We make use of oil mixture to refine grind the roller and also level die. The oil mixture is composed of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding the oil mix to the pellet machine, you must adjust the clearance in between roller as well as flat die to 0.1-0.3 mm. The grinding process ought to last 15-40 min.



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



Pretreatment of resources

The suitable wetness content of biomass materials need to in between 14% and 20%. Dry materials are hard to take shape, damp materials will certainly make the pellets loose. electric pellet mill of the raw materials should be less than the hole size of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm and also 8mm, and also the dimension of raw materials should be under 5mm, or they may obstruct the holes and also lower pellet production.




The adhesive force establishes the developing price of the pellets The majority of biomass products consist of lignin, which would certainly thaw under high temperature as well as work as binder. Yet some materials like rice husk has low glue pressure. It require to be blended with sawdust or binders to make pellets



The thickness and length of the timber pellets.

The thickness of timber pellets is identified by the opening dimension of the die. The size is determined by the slicer. In level die pellet machine, the slicer is installed under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to attain different dimensions. For your own use, it is better to be brief. For transportation as well as selling, it suggest to be a little lengthy.



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



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


When you completed making pellets, do not close the pellet machine down at once. Add some combined oil and also biomass materials to the pellet machine as well as let it run for 1-2 min. In this way, we can load the die holes with oil blend, to make sure that we can straight begin making pellets the following time. With this procedure, we can not just maintain the mold, but additionally save time. When visit here , loosen up the adjusting screw as well as remove the left materials.



The maintenance of roller, die, shafts and also gearbox

You should eliminate all hard items as well as metal blocks in basic materials before feeding them into the pellet machine, or they would create damages to the roller, die or main shaft. You can mount a tubular magnet on the feed hopper.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and the roller maintains high pressure during procedure. As there is no dust guard in the pellet machine, so you need to clean up the bearing every 2-5 hrs, and also lubricate it with oil. After every 8 working hours, the major shaft requirement to be fueled oil. The gearbox demand cleaning every half a year. If there is abnormal high warm in the transmission, you can utilize much better gear oil as well as enhance the clearance between the gears for maintenance. The attaching screw in the transmission component additionally need to be changed regularly.



How to change roller and die?

When the rollers wears, you can replace the roller covering or the whole set of roller. If the bearing get loosened or locked, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart and change it with a new one. If the ring die is repaired with screws, you require to shake the ring die carefully, and get rid of the screw with even strength.



In flat die pellet machine, the flat die is installed with retaining nuts in the keyway. On the 2 sides of the flat die, there are 2 symmetrical screw holes. You can use the screw driver to press them out, or utilize a magnet to pull them out. Throughout your pressing or drawing, keep the flat die shaking with a hammer, to ensure that the screw will not embeded the screw hole.



Security of the drive engine

Choose the matched power according to the necessary production. If the power is inadequate, the production will certainly be low as well as the pelletizing impact is poor. If the power is as well big, it will certainly consume more power, increase the weariness, as well as shorten the service life of roller and die.



The examination and also fixing must be carried out in power off problem. The machine should be placed near the working place, so regarding decrease the relocating time as high as feasible. Protect it from water logging, rainfall, electrical leakage, fire, etc.



Just when we use the pellet machine effectively and maintain it consistently can we make the most of the pellet machine and also prolong its working life.
