How to utilize and also keep timber pellet machine appropriately?<br>
Grinding prior to making use of

Most roller as well as level dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, as well as appeasing process, there are usually several dustcloths inside the die holes, which might influence the pelletizing effects and also manufacturing. As a result, before beginning a brand-new pellet machine, or after replacing a new die, you require to grind it thoroughly.



We make use of oil mixture to process grind the roller and flat die. The oil mix is made up of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding the oil combination to the pellet machine, you need to adjust the clearance in between roller and also level die to 0.1-0.3 mm. The grinding process needs to last 15-40 minutes.



For ring die pellet mill, the grinding process calls for more oil blend as well as longer time. The amount of oil combination is 10% that of pellet production per hour. The grinding time is 30-50 min. As well as the clearance between ring die as well as the roller is 0.1-0.4 mm.



Pretreatment of raw materials

The ideal dampness content of biomass materials should in between 14% and also 20%. Dry materials are hard to take form, moist materials will 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 also 8mm, and the size of raw materials need to be under 5mm, or they may block the holes and lower pellet manufacturing.



The adhesive pressure figures out the developing rate of the pellets Many biomass products contain lignin, which would certainly melt under high temperature and also serve as binder. Yet some materials like rice husk has reduced adhesive force. It need to be combined with sawdust or binders to make pellets




The thickness and size of the timber pellets.

The density of wood pellets is established by the opening size of the die. The length is established by the slicer. In flat 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 accomplish different dimensions. For your own use, it is better to be brief. For transportation and selling, it advise to be a little lengthy.



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



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

When you completed making pellets, do not shut the pellet machine down at the same time. Include some combined oil as well as biomass materials to the pellet machine and also allow it compete 1-2 minutes. By doing this, we can fill up the die holes with oil blend, to ensure that we can straight begin making pellets the following time. With this process, we can not just keep the mold, yet likewise conserve time. When the pellet machine stops, loosen up the adjusting screw and eliminate the left materials.



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

You ought to remove all tough objects and metal blocks in resources prior to feeding them into the pellet machine, or they would cause damage to the roller, die or main shaft. You can install a tubular magnet on the feed receptacle.




The heat inside the pelletizing chamber can rise to 80 ℃, and also the roller sustains high pressure during operation. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hours, and oil it with oil. After https://pabrikpavingblock.com/organic-fertilizer-pellet-making-machine/ working hours, the main shaft need to be fueled oil. richi pellet machine cleansing every half a year. If there is uncommon high heat in the transmission, you can make use of far better equipment oil and also raise the clearance in between the equipments for upkeep. The securing screw in the transmission part also require to be changed regularly.



Just how to replace roller as well as die?

When the rollers breaks, you can change the roller covering or the whole set of roller. If the bearing get loosened or locked, you require to change the bearing and even the shaft.



In ring die pellet machine, just loosen the hoop chuck, take the old ring die apart and change it with a new one. If the ring die is fixed with screws, you need to tremble the ring die carefully, and eliminate the screw with also stamina.



In level die pellet machine, the flat die is installed with maintaining nuts in the keyway. On the 2 sides of the flat die, there are two in proportion screw openings. You can use the screw driver to push them out, or use a magnet to draw them out. Throughout your pressing or pulling, keep the level die shaking with a hammer, to ensure that the screw won't stuck in the screw opening.



Defense of the drive engine

Choose the matched power according to the necessary production. If the power is insufficient, the production will be reduced as well as the pelletizing result is poor. If the power is too big, it will eat more power, increase the exhaustion, and reduce the life span of roller and die.



The examination and also repair must be accomplished in power off problem. The machine needs to be put near the functioning place, so as to minimize the moving time as long as possible. Secure it from water logging, rain, electric leakage, fire, and so on.



Only when we make use of the pellet machine correctly and preserve it frequently can we make the most of the pellet machine and prolong its working life.
