Exactly how to use and also keep timber pellet machine properly?<br>
Grinding before using

A lot of roller and flat dies in pellet machine are refined by high-heat treatment. After planing, exploration, milling, and also appeasing procedure, there are usually lots of dustcloths inside the die holes, which might affect the pelletizing results and also production. Consequently, before starting a brand-new pellet machine, or after replacing a new die, you require to grind it extensively.




We utilize oil blend 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. Prior to feeding the oil mix to the pellet machine, you ought to readjust the clearance between roller and also flat die to 0.1-0.3 mm. The grinding process needs to last 15-40 min.



For ring die pellet mill, the grinding procedure requires more oil mixture as well as longer time. The quantity of oil blend is 10% that of pellet production per hr. The grinding time is 30-50 minutes. And the clearance between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of raw materials

The ideal dampness web content of biomass materials must in between 14% and also 20%. Dry products are upsetting shape, moist materials will make the pellets loose. The dimension of the raw materials need to be less than the hole size of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm and also 8mm, as well as the dimension of resource s must be under 5mm, or they may obstruct the holes and decrease pellet manufacturing.



The adhesive force figures out the developing price of the pellets Many biomass materials contain lignin, which would certainly melt under high temperature as well as function as binder. Yet view it now like rice husk has low glue force. It require to be combined with sawdust or binders to make pellets



The thickness and size of the timber pellets.

The thickness of wood pellets is identified by the opening dimension of the die. The length is figured out by the slicer. In https://bestiya.net/ , the slicer is installed under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be gotten used to accomplish different sizes. For your very own usage, it is much better to be brief. For transport and also selling, it advise to be a little lengthy.



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



Do not shut down the machine right after making pellets.

When you ended up making pellets, do not shut the pellet machine down simultaneously. Add some blended oil and also biomass products to the pellet machine and also let it compete 1-2 min. This way, we can fill the die holes with oil mix, so that we can straight start making pellets the next time. With this procedure, we can not only maintain the mold, yet also conserve time. When the pellet machine stops, loosen the readjusting screw and also clear away the left products.




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

You must eliminate all difficult things as well as metal blocks in basic materials prior to feeding them into the pellet machine, or they would certainly trigger damages 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 ℃, and the roller sustains high pressure throughout procedure. As there is no dust protector in the pellet machine, so you need to clean up the bearing every 2-5 hours, and oil it with oil. After every 8 working hours, the main shaft demand to be oiled. The gearbox need cleaning every half a year. If there is unusual high warm in the transmission, you can make use of far better equipment oil as well as increase the clearance in between the gears for upkeep. The attaching screw in the transmission component likewise need to be changed routinely.



Exactly how to replace roller and also die?

When the rollers breaks, you can change the roller covering or the entire set of roller. If the bearing obtain loosened 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 as well as replace it with a new one. If the ring die is fixed with screws, you require to shake the ring die delicately, and also eliminate the screw with even stamina.



In level die pellet machine, the flat die is installed with keeping nuts in the keyway. On the 2 sides of the flat die, there are two balanced screw openings. You can make use of the screw chauffeur to press them out, or utilize a magnet to pull them out. Throughout your pushing or pulling, keep the flat die shaking with a hammer, so that the screw will not embeded the screw opening.



Defense of the drive engine

Pick the matched power according to the required production. If the power is inadequate, the production will certainly be reduced as well as the pelletizing impact is poor. If the power is also large, it will certainly take in even more power, increase the exhaustion, and reduce the service life of roller and die.



The test as well as fixing must be executed in power off problem. The machine should be positioned near the working area, so as to decrease the moving time as much as feasible. Shield it from water logging, rainfall, electrical leakage, fire, and so on.



Only when we utilize the pellet machine appropriately as well as preserve it consistently can we maximize the pellet machine as well as lengthen its working life.
