Exactly how to use and keep timber pellet machine correctly?<br>
Grinding prior to making use of

Many roller and level dies in pellet machine are refined by high-heat therapy. After planing, boring, milling, and also quenching process, there are normally many rags inside the die holes, which might influence the pelletizing effects and also manufacturing. Therefore, before starting a brand-new pellet machine, or after replacing a brand-new die, you need to grind it completely.



We use oil blend to process grind the roller and flat die. The oil combination is made up of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil mix to the pellet machine, you must readjust the clearance between roller as well as level die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 minutes.



For ring die pellet mill, the grinding process requires more oil mixture and also longer time. The quantity of oil combination is 10% that of pellet manufacturing per hr. The grinding time is 30-50 minutes. And also the clearance 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 materials should in between 14% and also 20%. Dry products are upsetting form, damp products will make the pellets loose. The size of the raw materials must be less than the hole dimension of pellet mill dies. Normally, the hole dimension of the pellet mill die is 6mm and 8mm, and the dimension of basic materials should be under 5mm, or they may block the holes and also lower pellet manufacturing.



The adhesive pressure figures out the forming price of the pellets The majority of biomass products contain lignin, which would thaw under high temperature and act as binder. However some products like rice husk has low sticky pressure. It need to be combined with sawdust or binders to make pellets



The density and size of the wood pellets.

The density of wood pellets is figured out by the opening dimension of the die. The size is identified by the slicer. In wool pellet machine , the slicer is installed 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 achieve different sizes. For your own use, it is better to be brief. For transport as well as marketing, it suggest to be a little long.



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 cooler. Quick cooling down can improve the firmness of the wood pellets, and facilitate storage space and transportation.




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

When you finished making pellets, don't shut the pellet machine down at once. Add some mixed oil as well as biomass materials to the pellet machine as well as let it compete 1-2 min. By doing pe pelletizing machine , we can fill up the die openings with oil blend, so that we can directly begin making pellets the following time. With this process, we can not only maintain the mold and mildew, however also save time. When the pellet machine quits, loosen the readjusting screw and also eliminate the left materials.



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

You should eliminate all tough things and metal blocks in resources before feeding them into the pellet machine, or they would trigger damages to the roller, die or main shaft. You can set up a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and the roller sustains high pressure during operation. As there is no dirt guard in the pellet machine, so you need to clean up the bearing every 2-5 hours, and also oil it with oil. After chicken feed machine , the major shaft need to be fueled oil. The transmission demand cleaning every half a year. If there is unusual high heat in the gearbox, you can use far better equipment oil and also enhance the clearance in between the gears for upkeep. The attaching screw in the transmission part also require to be changed routinely.



Just how to replace roller and die?

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



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart as well as change it with a new one. If the ring die is fixed with screws, you require to shake the ring die carefully, as well as remove the screw with also strength.



In flat die pellet machine, the level die is mounted with retaining nuts in the keyway. On the 2 sides of the flat die, there are two balanced screw holes. You can utilize the screw vehicle driver to push them out, or make use of a magnet to pull them out. Throughout your pressing or pulling, keep the level die shaking with a hammer, to ensure that the screw will not stuck in the screw opening.



Protection of the drive engine

Choose the matched power according to the required manufacturing. If the power is not nearly enough, the production will certainly be low and also the pelletizing impact is poor. If the power is also big, it will certainly consume even more power, increase the weariness, as well as reduce the service life of roller as well as die.



The test and also repair need to be executed in power off problem. The machine ought to be positioned near the functioning place, so as to decrease the relocating time as much as feasible. Shield it from water logging, rainfall, electric leak, fire, etc.



Only when we make use of the pellet machine correctly and also maintain it frequently can we make the most of the pellet machine and lengthen its functioning life.
