How to use and also maintain wood pellet machine effectively?<br>
Grinding prior to utilizing

The majority of roller and also flat dies in pellet machine are refined by high-heat treatment. After planing, drilling, milling, and also satiating process, there are usually lots of rags inside the die holes, which might influence the pelletizing effects and manufacturing. Consequently, before starting a new pellet machine, or after replacing a new die, you need to grind it extensively.



We make use of oil blend to process grind the roller and also level die. The oil combination is composed of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Before feeding the oil combination to the pellet machine, you must readjust the clearance in between roller and also level die to 0.1-0.3 mm. The grinding process ought to last 15-40 min.



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




Pretreatment of basic materials

The suitable dampness material of biomass products should between 14% as well as 20%. Dry materials are hard to take form, moist products will certainly make the pellets loose. low cost pellet machine of the raw materials must be less than the hole size of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm and also 8mm, and the size of raw materials need to be under 5mm, or they might obstruct the holes and also lower pellet production.



The sticky pressure determines the creating rate of the pellets The majority of biomass products consist of lignin, which would melt under heat and also work as binder. However some materials like rice husk has low adhesive pressure. It require to be combined with sawdust or binders to make pellets



The density and also size of the timber pellets.

The thickness of wood pellets is established by the hole dimension of the die. The size 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 set up outside the ring die. Both of them can be gotten used to accomplish various dimensions. For your very own usage, it is much better to be short. For transportation and also marketing, it recommend to be a little long.



After the timber pellets appear from the pellet machine, they are warm with some heavy steams. They can be dried and cooled down in an open area, or by a counter-flow cooler. Quick cooling down can enhance the solidity of the wood pellets, and also promote storage and transportation.



Do not shut down the machine right after making pellets.

When you finished making pellets, do not close the pellet machine down simultaneously. Include some mixed oil and biomass products to the pellet machine and also allow it compete 1-2 min. This way, we can fill up the die openings with oil blend, to ensure that we can directly start making pellets the following time. With this process, we can not only preserve the mold and mildew, however likewise conserve time. When the pellet machine quits, loosen the adjusting screw and remove the left products.



The upkeep of roller, die, shafts and also gearbox

You should remove all difficult things and steel blocks in raw materials prior to feeding them into the pellet machine, or they would trigger damages to the roller, die or main shaft. You can install a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure throughout operation. As there is no dirt protector in the pellet machine, so you require to clean up the bearing every 2-5 hrs, as well as oil it with oil. After every 8 functioning hrs, the major shaft demand to be fueled oil. The transmission need cleansing every half a year. If there is unusual high warmth in the gearbox, you can make use of far better equipment oil and also boost the clearance in between the gears for upkeep. The fastening screw in the transmission component likewise need to be changed on a regular basis.



Exactly how to replace roller as well as die?

When the rollers breaks, you can change the roller covering or the entire collection of roller. If the bearing get loosened or locked, you need to replace the bearing and also even 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 repaired with screws, you need to shake the ring die carefully, and also remove the screw with even strength.



In flat die pellet machine, the level die is set up 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 vehicle driver to press them out, or utilize a magnet to draw them out. Throughout home made pellet mill pressing or pulling, maintain the level die vibrating with a hammer, so that the screw will not stuck in the screw hole.



Security of the drive engine

Select the matched power according to the needed production. If the power is inadequate, the manufacturing will certainly be reduced and also the pelletizing result is poor. If the power is as well huge, it will eat more power, increase the fatigue, and also shorten the service life of roller and die.



The test and repair work should be performed in power off condition. The machine should be positioned near the working area, so regarding reduce the relocating time as much as feasible. Secure it from water logging, rain, electric leak, fire, etc.



Just when we utilize the pellet machine properly and also maintain it frequently can we maximize the pellet machine as well as lengthen its working life.
