Just how to utilize and keep timber pellet machine effectively?<br>
Grinding before making use of

Most roller and flat dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, and appeasing procedure, there are typically lots of dustcloths inside the die openings, which may influence the pelletizing effects as well as production. Therefore, prior to beginning a brand-new pellet machine, or after replacing a brand-new die, you require to grind it completely.



We use oil blend to process grind the roller as well as level die. The oil blend 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 should readjust the clearance between roller and level die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 minutes.



For ring die pellet mill, the grinding process needs more oil blend as well as longer time. The amount of oil blend is 10% that of pellet manufacturing per hour. The grinding time is 30-50 min. And also the clearance in between ring die and the roller is 0.1-0.4 mm.



Pretreatment of raw materials


The ideal dampness content of biomass products ought to in between 14% as well as 20%. Dry products are hard to take form, moist products will certainly make the pellets loose. The size of the raw products ought to be less than the hole size of pellet mill dies. Typically, the hole dimension of the pellet mill die is 6mm and 8mm, and also the dimension of raw materials ought to be under 5mm, or they might block the holes and also reduce pellet manufacturing.



The glue pressure determines the creating price of the pellets Most biomass products contain lignin, which would thaw under high temperature and also work as binder. Yet some products like rice husk has reduced glue force. It require to be combined with sawdust or binders to make pellets



The density and also length of the wood pellets.

The thickness of timber pellets is identified by the opening size of the die. The size is established by the slicer. In level die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to attain various sizes. For your very own use, it is far better to be short. For transport and also marketing, 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 out and also cooled in an open area, or by a counter-flow cooler. Quick cooling down can improve view website of the timber pellets, and also promote storage and also transport.



Do not shut down the machine right after making pellets.

When you completed making pellets, do not close the pellet machine down at the same time. Add some combined oil and biomass materials to the pellet machine and let it compete 1-2 minutes. In this way, we can fill up the die holes with oil mixture, to make sure that we can directly start making pellets the following time. With this process, we can not only preserve the mold, yet also save time. When the pellet machine quits, loosen the readjusting screw as well as clear away the left materials.



The maintenance of roller, die, shafts and gearbox

You ought to get rid of all tough objects and also metal blocks in raw materials prior to feeding them right into the pellet machine, or they would cause damage to the roller, die or main shaft. You can mount a tubular magnet on the feed hopper.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure during procedure. As there is no dust guard in the pellet machine, so you require to clean up the bearing every 2-5 hours, as well as oil it with oil. After every 8 functioning hrs, the main shaft requirement to be oiled. Discover More Here cleansing every half a year. If there is unusual high warm in the gearbox, you can make use of better gear oil and raise the clearance in between the gears for maintenance. The attaching screw in the transmission part likewise need to be replaced regularly.



How to replace roller and also die?

When the rollers breaks, you can change the roller shell or the whole collection of roller. If the bearing get loosened or locked, you require to replace the bearing and also 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, as well as get rid of the screw with even toughness.



In flat die pellet machine, the flat die is mounted with maintaining nuts in the keyway. On Richi machinery of the level die, there are 2 balanced screw openings. You can utilize the screw driver to press them out, or use a magnet to draw them out. Throughout your pressing or drawing, maintain the flat die shaking with a hammer, to ensure that the screw will not stuck in the screw hole.



Defense of the drive engine

Pick the matched power according to the needed manufacturing. If the power is not enough, the production will be low as well as the pelletizing effect is poor. If the power is also huge, it will certainly take in even more power, accelerate the exhaustion, and also reduce the service life of roller and also die.



The exam and also fixing must be carried out in power off problem. The machine should be positioned near the functioning place, so as to minimize the relocating time as long as possible. Safeguard it from water logging, rain, electrical leak, fire, and so on.




Just when we use the pellet machine appropriately and also keep it frequently can we take full advantages of the pellet machine and extend its functioning life.
