Exactly how to utilize as well as maintain timber pellet machine properly?<br>
Grinding before using

A lot of roller as well as flat dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, and also richi pellet machine , there are normally many dustcloths inside the die holes, which may influence the pelletizing results and manufacturing. Therefore, prior to starting a new pellet machine, or after changing a new die, you require to grind it extensively.




We use oil mixture to process grind the roller and also level die. The oil mix is composed of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Prior to feeding the oil mix to the pellet machine, you must change the clearance between roller and flat die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 min.



For ring die pellet mill, the grinding process needs more oil mixture 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 the clearance in between ring die as well as the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The appropriate wetness material of biomass materials should in between 14% and also 20%. Dry materials are upsetting form, moist materials will make the pellets loose. The size of the raw materials 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, as well as the size of resources should be under 5mm, or they may obstruct the holes and minimize pellet production.



The glue force figures out the forming rate of the pellets Most biomass materials include lignin, which would certainly thaw under high temperature and also work as binder. Yet some products like rice husk has low sticky force. It need to be mixed with sawdust or binders to make pellets



The thickness as well as size of the timber pellets.

The density of timber pellets is established by the hole size of the die. The size is identified by the slicer. In flat die pellet machine, the slicer is mounted under the flat die, while in ring die pellet machine, the slicer is installed outside the ring die. Both of them can be adapted to accomplish different dimensions. For your own use, it is far better to be short. For transportation and selling, it recommend to be a little long.



After the timber pellets come out from the pellet machine, they are warm with some heavy steams. feed pelletizer for sale can be dried and cooled down in an open field, or by a counter-flow colder. Quick cooling can enhance the solidity of the wood pellets, and also help with storage and transport.



Do not close down the machine right after making pellets.

When you completed making pellets, don't shut the pellet machine down simultaneously. Add some mixed oil and also biomass materials to the pellet machine and also allow it compete 1-2 minutes. By doing this, we can load the die openings with oil mixture, to ensure that we can directly begin making pellets the following time. With this process, we can not only maintain the mold and mildew, however additionally conserve time. When the pellet machine stops, loosen up the adjusting screw and clear away the left products.



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

You ought to remove all tough things and also steel blocks in basic materials before feeding them into the pellet machine, or they would trigger damages to the roller, die or primary shaft. You can mount 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 during procedure. As there is no dirt guard in the pellet machine, so you need to tidy up the bearing every 2-5 hrs, and lube it with oil. After every 8 working hours, the main shaft requirement to be fueled oil. The gearbox requirement cleansing every half a year. If there is irregular high warmth in the transmission, you can utilize much better gear oil as well as enhance the clearance between the equipments for upkeep. The attaching screw in the transmission component also require to be replaced frequently.



Exactly how to replace roller as well as die?

When the rollers wears out, you can change the roller covering or the whole set of roller. If the bearing obtain loosened or secured, you need to change the bearing as well as even the shaft.



In ring die pellet machine, just loosen up the hoop chuck, take the old ring die apart as well as replace it with a brand-new one. If the ring die is fixed with screws, you require to tremble the ring die gently, and also get rid of the screw with also stamina.



In flat die pellet machine, the level die is mounted with maintaining nuts in the keyway. On the 2 sides of the level die, there are two symmetrical screw openings. You can utilize the screw vehicle driver to push them out, or utilize a magnet to pull them out. During your pushing or pulling, keep the flat die shaking with a hammer, so that the screw won't stuck in the screw hole.



Security of the drive engine

Select the matched power according to the necessary manufacturing. If the power is not nearly enough, the manufacturing will certainly be reduced and also the pelletizing result is poor. If the power is too huge, it will certainly consume more power, accelerate the exhaustion, as well as reduce the life span of roller and die.



The examination as well as repair service ought to be accomplished in power off condition. The machine needs to be placed near the functioning area, so regarding lower the relocating time as high as possible. Shield it from water logging, rainfall, electrical leakage, fire, etc.




Just when we utilize the pellet machine appropriately and also maintain it on a regular basis can we maximize the pellet machine and also lengthen its working life.
