How to use as well as preserve timber pellet machine correctly?<br>
Grinding before utilizing

Many roller and flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, as well as relieving process, there are normally many cloths inside the die openings, which might influence the pelletizing impacts and production. As a result, before starting a brand-new pellet machine, or after changing a new die, you need to grind it completely.




We utilize oil mixture to process grind the roller and level die. The oil combination is composed of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil blend to the pellet machine, you must readjust the clearance between roller and also flat die to 0.1-0.3 mm. The grinding process needs to last 15-40 min.



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



Pretreatment of resources

The ideal moisture content of biomass products must between 14% and 20%. Dry products are hard to take form, damp products will certainly make the pellets loose. The dimension of the raw materials must be less than the hole size of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm and 8mm, and the dimension of resources should be under 5mm, or they may block the holes and also minimize pellet production.



The sticky force figures out the forming price of the pellets A lot of biomass materials consist of lignin, which would certainly thaw under heat as well as function as binder. However some products like rice husk has reduced sticky force. It need to be mixed with sawdust or binders to make pellets



The thickness as well as length of the timber pellets.

The density of wood pellets is established by the opening size of the die. The length is determined by the slicer. In level die pellet machine, the slicer is mounted under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adapted to attain various dimensions. For your very own use, it is far better to be brief. For transportation as well as marketing, it suggest to be a little long.




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



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

When you completed making pellets, don't close the pellet machine down at once. Include some combined oil and biomass products to the pellet machine and allow it run for 1-2 minutes. This way, we can fill the die holes with oil mixture, to ensure that we can straight begin making pellets the next time. With https://trackchairclips.com/biomass-fuel-pellet-machine/ , we can not only preserve the mold, however additionally conserve time. When the pellet machine stops, loosen up the changing screw as well as remove the left products.



The upkeep of roller, die, shafts and gearbox

You ought to remove all tough items and steel blocks in raw materials before feeding them into the pellet machine, or they would certainly trigger damage to the roller, die or main shaft. You can mount a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, as well as the roller maintains high pressure throughout operation. As there is click for info in the pellet machine, so you need to tidy up the bearing every 2-5 hours, and also lubricate it with oil. After every 8 functioning hours, the main shaft need to be oiled. The transmission requirement cleansing every half a year. If there is irregular high heat in the transmission, you can utilize much better equipment oil as well as enhance the clearance in between the equipments for upkeep. The fastening screw in the transmission part additionally require to be changed frequently.



Just how to replace roller and also die?

When the rollers wears, you can replace the roller shell or the entire collection of roller. If the bearing obtain loose or locked, you require to change the bearing and also the shaft.



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



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



Security of the drive engine

Choose the matched power according to the necessary production. If floating fish feed making machine is not nearly enough, the manufacturing will be low as well as the pelletizing impact is poor. If the power is as well huge, it will eat even more power, speed up the fatigue, and shorten the service life of roller as well as die.



The exam as well as repair need to be executed in power off condition. The machine should be placed near the working place, so as to minimize the relocating time as long as possible. Shield it from water logging, rainfall, electrical leakage, fire, and so on.



Just when we utilize the pellet machine correctly and also maintain it frequently can we take full advantages of the pellet machine as well as lengthen its working life.
