How to use and also maintain timber pellet machine appropriately?<br>
Grinding prior to using

The majority of roller and also level dies in pellet machine are refined by high-heat therapy. After planing, exploration, milling, and also appeasing procedure, there are usually lots of cloths inside the die holes, which may influence the pelletizing results and also manufacturing. For that reason, prior to beginning a brand-new pellet machine, or after changing a new die, you require to grind it extensively.



We utilize oil mix to process grind the roller and level 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 level die to 0.1-0.3 mm. The grinding procedure must last 15-40 min.



For ring die pellet mill, the grinding procedure requires even more oil blend and also longer time. The amount of oil blend is 10% that of pellet production per hr. 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 suitable wetness web content of biomass materials must in between 14% and also 20%. Dry products are hard to take shape, damp products will make the pellets loose. The dimension of the raw products ought 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 also the dimension of raw materials should be under 5mm, or they might block the holes as well as lower pellet manufacturing.



The adhesive pressure determines the forming price of the pellets Most biomass materials contain lignin, which would certainly melt under high temperature as well as function as binder. Yet some products like rice husk has reduced sticky pressure. It need to be blended with sawdust or binders to make pellets



The thickness and also length of the timber pellets.

The thickness of timber pellets is determined by the hole size of the die. The length is identified by the slicer. In flat 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 adjusted to accomplish various sizes. For your very own usage, it is far better to be short. 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 vapors. They can be dried and also cooled in an open field, or by a counter-flow cooler. Quick cooling can improve the solidity of the timber pellets, and also assist in storage space and transport.



Do not close down the machine right after making pellets.

When you completed making pellets, don't shut the pellet machine down at the same time. Include some blended oil and biomass materials to the pellet machine and allow it run for 1-2 min. By doing this, we can load the die openings with oil mixture, to make sure that we can directly begin making pellets the following time. With investigate this site , we can not just preserve the mold and mildew, yet also conserve time. When pop over to this site , loosen up the changing screw and also clear away the left materials.




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

You need to get rid of all tough items as well as steel blocks in resources prior to feeding them right into the pellet machine, or they would create damages to the roller, die or main shaft. You can mount a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can rise to 80 ℃, and also the roller maintains high pressure throughout procedure. As there is no dirt guard in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and lube it with oil. After every 8 functioning hrs, the primary shaft requirement to be fueled oil. The gearbox demand cleansing every half a year. If there is uncommon high warm in the gearbox, you can utilize much better gear oil and also enhance the clearance in between the equipments for upkeep. The fastening screw in the transmission part likewise need to be changed consistently.



Exactly how to replace roller and also die?

When the rollers wears, you can replace the roller shell or the whole set of roller. If the bearing get loose or secured, 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 also replace it with a new one. If the ring die is taken care of with screws, you need to shake the ring die carefully, as well as remove the screw with even toughness.



In level die pellet machine, the flat die is mounted with keeping nuts in the keyway. On the 2 sides of the level die, there are two in proportion screw openings. You can use the screw vehicle driver to push them out, or use a magnet to draw them out. Throughout your pushing or drawing, keep the level die vibrating with a hammer, to make sure that the screw will not stuck in the screw hole.



Defense of the drive engine

Choose the matched power according to the required manufacturing. If the power is inadequate, the production will be reduced as well as the pelletizing result is poor. If the power is as well huge, it will certainly consume more power, speed up the exhaustion, as well as shorten the life span of roller as well as die.



The test and also repair should be accomplished in power off problem. The machine should be positioned near the working place, so as to lower the relocating time as long as possible. Safeguard it from water logging, rain, electric leakage, fire, and so on.



Only when we make use of the pellet machine correctly as well as keep it frequently can we make the most of the pellet machine and also extend its functioning life.
