Notes

Exactly how to use as well as preserve timber pellet machine appropriately?<br>
Grinding before making use of

Most roller as well as level dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, and also relieving process, there are usually many cloths inside the die openings, which may influence the pelletizing results and also production. Consequently, prior to starting a new pellet machine, or after changing a new die, you need to grind it extensively.



We make use of oil blend to refine grind the roller as well as level die. The oil mixture is composed of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil mixture to the pellet machine, you need to adjust the clearance between roller as well as flat die to 0.1-0.3 mm. The grinding procedure must last 15-40 min.



For ring die pellet mill, the grinding procedure requires more oil combination as well as 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 and also the roller is 0.1-0.4 mm.




Pretreatment of basic materials

The appropriate dampness web content of biomass materials need to between 14% and 20%. Dry products are hard to take shape, moist materials will certainly make the pellets loose. second hand pellet mill of the raw materials must be less than the hole dimension of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm and also 8mm, and the size of resources need to be under 5mm, or they may obstruct the holes as well as decrease pellet production.



The adhesive pressure identifies the creating price of the pellets A lot of biomass materials include lignin, which would thaw under high temperature as well as function as binder. However some materials like rice husk has reduced adhesive pressure. It need to be mixed with sawdust or binders to make pellets



The thickness and length of the wood pellets.

The thickness of timber pellets is figured out by the opening dimension 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 attain various sizes. For your own use, it is far better to be short. For transport and marketing, it suggest to be a little long.



After the timber pellets come out from the pellet machine, they are warm with some steams. They can be dried and cooled down in an open field, or by a counter-flow colder. Quick cooling down can improve the hardness of the timber pellets, as well as facilitate storage and transport.



Do not shut down the machine right after making pellets.

When you finished making pellets, do not close the pellet machine down simultaneously. Add some combined oil as well as biomass products to the pellet machine and also let it run for 1-2 minutes. In this way, we can load the die openings with oil mix, to make sure that we can directly begin making pellets the following time. With this process, we can not just maintain the mold and mildew, however additionally save time. When the pellet machine stops, loosen the readjusting screw and also remove the left products.



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

You should get rid of all difficult items and also metal blocks in basic materials prior to feeding them right into the pellet machine, or they would certainly create damage to the roller, die or main shaft. You can install a tubular magnet on the feed hopper.



The heat inside the pelletizing chamber can reach up to 80 ℃, as well as the roller maintains high pressure throughout procedure. As there is Richi machine in the pellet machine, so you need to tidy up the bearing every 2-5 hours, and also lube it with oil. After every 8 functioning hrs, the primary shaft demand to be oiled. The gearbox demand cleansing every half a year. If there is abnormal high warmth in the gearbox, you can use far better equipment oil and also enhance the clearance between the equipments for upkeep. The fastening screw in the transmission part additionally need to be replaced consistently.



Just how to replace roller and die?

When the rollers wears, you can replace the roller shell or the entire collection of roller. If the bearing get loosened or secured, you require to change the bearing and also the shaft.



In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart as well as change it with a brand-new one. If the ring die is taken care of with screws, you need to drink the ring die gently, and also remove the screw with even toughness.



In flat die pellet machine, the level die is set up with preserving nuts in the keyway. On the 2 sides of the level die, there are two symmetrical screw openings. You can utilize the screw motorist to push them out, or make use of a magnet to pull them out. Throughout your pressing or drawing, keep the flat die shaking with a hammer, to make sure that the screw will not stuck in the screw opening.




Protection of the drive engine

Select the matched power according to the needed production. If click here for more info is inadequate, the manufacturing will be reduced as well as the pelletizing effect is poor. If the power is too huge, it will consume even more power, accelerate the exhaustion, and shorten the service life of roller as well as die.



The test and also repair need to be performed in power off problem. The machine needs to be placed near the working area, so as to lower the moving time as long as possible. Protect it from water logging, rain, electrical leakage, fire, and so on.



Just when we use the pellet machine correctly as well as maintain it consistently can we maximize the pellet machine and extend its working life.
