Just how to make use of and also preserve timber pellet machine effectively?<br>
Grinding before making use of

A lot of roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, exploration, milling, and also relieving process, there are generally many rags inside the die holes, which might affect the pelletizing results and also production. As a result, before starting a brand-new pellet machine, or after replacing a brand-new die, you need to grind it thoroughly.



We utilize oil mixture to refine grind the roller as well as flat die. The oil mix is composed of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil combination to the pellet machine, you ought to readjust the clearance between roller and flat die to 0.1-0.3 mm. The grinding procedure should last 15-40 minutes.



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



Pretreatment of basic materials

The ideal moisture web content of biomass products should in between 14% and also 20%. Dry materials are upsetting form, moist products will make the pellets loose. The dimension of the raw materials must be less than the hole size of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm and also 8mm, as well as the size of basic materials ought to be under 5mm, or they may obstruct the holes and also lower pellet production.



The sticky force establishes the forming price of the pellets The majority of biomass materials contain lignin, which would melt under high temperature as well as serve as binder. But some materials like rice husk has low sticky pressure. It need to be blended with sawdust or binders to make pellets



The density and length of the timber pellets.

The thickness of timber pellets is identified by the hole dimension of the die. The length is figured out by the slicer. In https://www.blablaface.net/floating-fish-feed-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. my blog of them can be adjusted to accomplish various sizes. For your very own usage, it is far better to be brief. For Richi machinery and also marketing, it recommend 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 out and also cooled down in an open field, or by a counter-flow cooler. Quick cooling down can boost the solidity of the wood pellets, and assist in storage and also transport.



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

When you completed making pellets, do not close the pellet machine down simultaneously. Add some mixed oil and also biomass products to the pellet machine and let it compete 1-2 min. This way, we can fill the die openings with oil mixture, so that we can directly begin making pellets the next time. With this process, we can not only preserve the mold, but also conserve time. When the pellet machine stops, loosen up the changing screw as well as eliminate the left materials.



The maintenance of roller, die, shafts and also transmission

You should eliminate all difficult items and also steel blocks in raw materials prior to feeding them right into the pellet machine, or they would certainly create damages to the roller, die or main shaft. You can set up a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can reach up to 80 ℃, as well as the roller sustains high pressure throughout procedure. As there is no dirt protector in the pellet machine, so you need to tidy up the bearing every 2-5 hours, and lube it with oil. After every 8 functioning hrs, the main shaft demand to be oiled. The transmission need cleansing every half a year. If there is irregular high warmth in the transmission, you can utilize better equipment oil as well as increase the clearance in between the gears for upkeep. The attaching screw in the transmission component additionally need to be changed consistently.




How to replace roller as well as die?

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



In ring die pellet machine, just loosen up the hoop chuck, take the old ring die apart and also change it with a brand-new one. If the ring die is fixed with screws, you need to shake the ring die gently, as well as eliminate the screw with also strength.



In level die pellet machine, the level die is set up with retaining nuts in the keyway. On the 2 sides of the flat die, there are 2 in proportion screw holes. You can make use of the screw chauffeur to press them out, or make use of a magnet to draw them out. Throughout your pressing or drawing, keep the level die shaking with a hammer, so that the screw will not stuck in the screw opening.




Protection of the drive engine

Select the matched power according to the needed manufacturing. If the power is not nearly enough, the manufacturing will be reduced and also the pelletizing impact is poor. If the power is as well large, it will take in more power, speed up the fatigue, as well as shorten the life span of roller and die.



The examination as well as repair service should be performed in power off condition. The machine ought to be placed near the working location, so regarding lower the moving time as high as possible. Secure it from water logging, rain, electric leakage, fire, etc.



Only when we make use of the pellet machine properly and keep it consistently can we take full advantages of the pellet machine and lengthen its working life.
