Exactly how to use as well as keep timber pellet machine properly?<br>
Grinding prior to utilizing

A lot of roller as well as flat dies in pellet machine are refined by high-heat therapy. After planing, drilling, milling, and quenching process, there are normally lots of dustcloths inside the die openings, which may influence the pelletizing effects and also manufacturing. Consequently, prior to beginning a brand-new pellet machine, or after changing a new die, you require to grind it extensively.



We use oil mix to refine grind the roller as well as flat die. The oil combination is made up of 20% great sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding https://www.openlearning.com/u/richipelletmill-rhrqq8/ to the pellet machine, you must change the clearance between roller and level die to 0.1-0.3 mm. The grinding process ought to last 15-40 min.



For ring die pellet mill, the grinding process requires even more oil blend and also longer time. The quantity of oil blend is 10% that of pellet manufacturing per hour. The grinding time is 30-50 minutes. And also the clearance between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of resources

The ideal moisture material of biomass products should between 14% and 20%. Dry materials are upsetting shape, wet products will make the pellets loose. The dimension of the raw products need to be less than the hole size of pellet mill dies. Typically, the hole dimension of the pellet mill die is 6mm and 8mm, and also the dimension of basic materials must be under 5mm, or they might block the holes as well as lower pellet production.



The adhesive force identifies the creating rate of the pellets A lot of biomass materials have lignin, which would melt under high temperature and also act as binder. However some products like rice husk has reduced sticky force. It require to be blended with sawdust or binders to make pellets



The thickness as well as length of the timber pellets.

The density of wood pellets is determined by the hole size of the die. The size is determined by the slicer. In level die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is set up outside the ring die. Both of them can be adjusted to achieve various sizes. For your own usage, it is much better to be brief. For transport and also selling, it advise to be a little lengthy.



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



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 mixed oil and biomass materials to the pellet machine and also allow it run for 1-2 minutes. In this way, we can fill up the die openings with oil combination, to make sure that we can directly start making pellets the following time. With this process, we can not only preserve the mold, yet likewise conserve time. When the pellet machine quits, loosen the readjusting screw as well as remove the left materials.



The upkeep of roller, die, shafts and transmission

You should eliminate all tough objects and also 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 set up a tubular magnet on the feed hopper.



The heat inside the pelletizing chamber can reach up to 80 ℃, as well as the roller maintains high pressure during procedure. As there is richi pellet machine in the pellet machine, so you require to clean up the bearing every 2-5 hours, as well as oil it with oil. After every 8 functioning hours, the primary shaft demand to be fueled oil. The transmission need cleaning every half a year. If there is unusual high heat in the gearbox, you can use better equipment oil as well as boost the clearance between the gears for maintenance. The attaching screw in the transmission component additionally require to be replaced consistently.



Exactly how to change roller and also die?

When the rollers breaks, you can replace the roller covering or the entire 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, simply loosen the hoop chuck, take the old ring die apart and change it with a brand-new one. If the ring die is taken care of with screws, you need to drink the ring die carefully, as well as eliminate the screw with also stamina.



In level die pellet machine, the level die is mounted with maintaining nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw openings. You can utilize the screw vehicle driver to press them out, or use a magnet to pull them out. During your pressing or pulling, maintain the flat die vibrating with a hammer, so that the screw will not embeded the screw opening.





Protection of the drive engine

Pick the matched power according to the necessary manufacturing. If the power is not nearly enough, the production will certainly be low and also the pelletizing effect is poor. If the power is too huge, it will certainly eat more power, accelerate the fatigue, as well as shorten the service life of roller as well as die.



The examination and repair must be carried out in power off condition. The machine should be placed near the working location, so regarding reduce the moving time as high as possible. Secure it from water logging, rain, electrical leak, fire, and so on.



Just when we utilize the pellet machine effectively and maintain it on a regular basis can we maximize the pellet machine and also lengthen its functioning life.
