Exactly how to make use of as well as preserve wood pellet machine appropriately?<br>
Grinding before using

A lot of roller and also level dies in pellet machine are refined by high-heat therapy. After planing, boring, milling, cpm pellet mill for sale as appeasing procedure, there are generally numerous dustcloths inside the die openings, which may affect the pelletizing results and also manufacturing. Consequently, before starting a new pellet machine, or after changing a brand-new die, you require to grind it thoroughly.



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



For ring die pellet mill, the grinding procedure needs even more oil mixture and also longer time. The amount of oil mixture is 10% that of pellet manufacturing per hr. The grinding time is 30-50 min. And the clearance between ring die and the roller is 0.1-0.4 mm.




Pretreatment of resources

The appropriate wetness content of biomass materials need to in between 14% as well as 20%. Dry materials are upsetting shape, damp materials will make the pellets loose. The size of the raw products should be less than the hole size of pellet mill dies. Normally, wood pellet press of the pellet mill die is 6mm as well as 8mm, and the size of resources must be under 5mm, or they might block the holes as well as reduce pellet production.



The adhesive force identifies the forming rate of the pellets Many biomass materials consist of lignin, which would certainly thaw under high temperature and also serve as binder. But some products like rice husk has reduced adhesive force. It need to be mixed with sawdust or binders to make pellets



The density and also size of the wood pellets.

The density of wood pellets is identified by the hole dimension of the die. The size is identified by the slicer. In flat die pellet machine, the slicer is set up under the flat die, while in ring die pellet machine, the slicer is installed outside the ring die. Both of them can be adjusted to achieve various sizes. For your very own usage, it is better to be brief. For transport and also marketing, it recommend to be a little long.



After the timber pellets appear from the pellet machine, they are warm with some vapors. They can be dried out as well as cooled down in an open area, or by a counter-flow colder. Quick cooling down can boost the hardness of the wood pellets, as well as assist in storage as well as transport.



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

When you finished making pellets, don't shut the pellet machine down at the same time. Add some blended oil and biomass products to the pellet machine and also allow it run for 1-2 minutes. This way, we can fill the die openings with oil mixture, to ensure that we can straight begin making pellets the following time. With this process, we can not only maintain the mold, yet also conserve time. When the pellet machine quits, loosen the adjusting screw and also eliminate the left materials.



The maintenance of roller, die, shafts as well as transmission

You ought to eliminate all difficult items as well as metal blocks in basic materials before feeding them right into the pellet machine, or they would trigger damage to the roller, die or primary shaft. You can mount a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can rise to 80 ℃, as well as the roller maintains high pressure during procedure. As there is no dirt guard in the pellet machine, so you need to clean up the bearing every 2-5 hours, and oil it with oil. After every 8 functioning hrs, the major shaft demand to be fueled oil. The gearbox demand cleansing every half a year. If there is abnormal high warmth in the transmission, you can use far better equipment oil and also raise the clearance in between the equipments for upkeep. The securing screw in the transmission component additionally require to be replaced consistently.



Just how to replace roller and die?

When the rollers breaks, you can replace the roller shell or the whole set of roller. If the bearing get loose or secured, you require 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 change it with a new one. If the ring die is taken care of with screws, you require to shake the ring die gently, and remove the screw with even strength.



In flat die pellet machine, the level die is installed with retaining nuts in the keyway. On the 2 sides of the flat die, there are two in proportion screw holes. You can make use of the screw vehicle driver to push them out, or use a magnet to draw them out. During your pressing or pulling, keep the flat die vibrating with a hammer, to make sure that the screw will not stuck in the screw hole.



Protection of the drive engine


Pick the matched power according to the needed manufacturing. If the power is inadequate, the manufacturing will certainly be low and also the pelletizing impact is poor. If the power is as well huge, it will certainly take in more power, increase the fatigue, and also reduce the life span of roller and also die.



The test and fixing should be executed in power off problem. The machine must be positioned near the working location, so regarding lower the moving time as long as possible. Safeguard it from water logging, rainfall, electric leak, fire, etc.



Only when we utilize the pellet machine effectively and also preserve it consistently can we take full advantages of the pellet machine as well as extend its working life.
