Exactly how to utilize as well as maintain timber pellet machine properly?<br>
Grinding before using

Many roller and also flat dies in pellet machine are processed by high-heat treatment. After planing, boring, milling, and also quenching procedure, there are typically lots of rags inside the die holes, which might affect the pelletizing effects and also production. As a result, before beginning a brand-new pellet machine, or after changing a new die, you need to grind it completely.



We use oil mixture to refine grind the roller and also level die. The oil combination is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil combination to the pellet machine, you must change the clearance between roller and flat die to 0.1-0.3 mm. The grinding process must last 15-40 minutes.



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



Pretreatment of resources

The appropriate moisture content of biomass materials ought to in between 14% and 20%. site here are upsetting form, wet materials will make the pellets loose. animal pellet mill of the raw materials need to be less than the hole dimension of pellet mill dies. Usually, the hole size of the pellet mill die is 6mm and also 8mm, and the dimension of raw materials must be under 5mm, or they may block the holes and also lower pellet manufacturing.



The sticky pressure identifies the forming rate of the pellets Many biomass products have lignin, which would certainly melt under high temperature as well as act as binder. Yet some products like rice husk has low glue force. It require to be blended with sawdust or binders to make pellets



The thickness and size of the timber pellets.

The thickness of timber pellets is established by the hole size of the die. The length is figured out by the slicer. In level die pellet machine, the slicer is set up under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adapted to accomplish different dimensions. For your very own use, it is better to be short. For transportation and marketing, it recommend to be a little long.



After the wood pellets appear from the pellet machine, they are warm with some steams. They can be dried out and cooled in an open field, or by a counter-flow colder. Quick cooling can enhance the solidity of the wood pellets, and help with storage as well as transport.




Do not close down the machine right after making pellets.

When you ended up making pellets, don't close the pellet machine down at the same time. Add some combined oil as well as biomass materials to the pellet machine as well as allow it run for 1-2 min. In this way, we can fill the die openings with oil mixture, to make sure that we can straight begin making pellets the next time. With this process, we can not only keep the mold and mildew, however likewise save time. When the pellet machine quits, loosen up the readjusting screw as well as clear away the left materials.



The maintenance of roller, die, shafts and gearbox

You must remove all difficult objects as well as steel blocks in raw materials prior to feeding them right into the pellet machine, or they would cause damages to the roller, die or main shaft. You can install a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can rise to 80 ℃, as well as the roller sustains high pressure throughout procedure. As there is no dust guard in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and oil it with oil. After every 8 working hrs, the main shaft demand to be oiled. The transmission demand cleansing every half a year. If there is abnormal high warm in the transmission, you can use far better equipment oil as well as enhance the clearance between the equipments for maintenance. The securing screw in the transmission part also require to be replaced on a regular basis.



Exactly how to change roller as well as die?

When the rollers breaks, you can replace the roller shell or the whole set of roller. If the bearing obtain loose or locked, you need to change the bearing as well as also the shaft.



In ring die pellet machine, simply 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 repaired with screws, you need to drink the ring die gently, and also remove the screw with also toughness.



In level die pellet machine, the level die is installed with retaining nuts in the keyway. On the 2 sides of the level die, there are 2 symmetrical screw openings. You can utilize the screw chauffeur to press them out, or utilize a magnet to draw them out. Throughout your pushing or pulling, maintain the flat die vibrating with a hammer, to make sure that the screw will not stuck in the screw opening.



Defense of the drive engine

Select the matched power according to the necessary production. If the power is not enough, the manufacturing will be low as well as the pelletizing effect is poor. If the power is as well large, it will certainly take in more power, increase the exhaustion, and reduce the life span of roller and die.




The exam and repair work need to be accomplished in power off problem. The machine ought to be positioned near the working location, so as to minimize the relocating time as much as possible. Protect it from water logging, rainfall, electric leakage, fire, and so on.



Just when we utilize the pellet machine correctly as well as maintain it consistently can we maximize the pellet machine and prolong its functioning life.
