How to use and maintain timber pellet machine effectively?<br>
Grinding before making use of

The majority of roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, drilling, milling, and satiating procedure, there are usually lots of rags inside the die holes, which may influence the pelletizing impacts and also manufacturing. Therefore, prior to beginning a new pellet machine, or after replacing a brand-new die, you require to grind it thoroughly.



We make use of oil mixture to process grind the roller as well as level die. richi machinery is composed of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding the oil blend to the pellet machine, you need to readjust the clearance between roller and level die to 0.1-0.3 mm. The grinding procedure needs to last 15-40 min.



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



Pretreatment of resources

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



The sticky pressure figures out the creating rate of the pellets A lot of biomass materials consist of lignin, which would certainly thaw under heat as well as act as binder. Yet some products like rice husk has reduced glue pressure. It require to be combined with sawdust or binders to make pellets



The thickness and length of the wood pellets.

The density of timber pellets is established by the opening size of the die. The size is established by the slicer. In fish food pellet making machine , the slicer is set up 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 different dimensions. For your very own use, it is much better to be brief. For transport and selling, it recommend to be a little long.



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




Do not close down the machine right after making pellets.

When you completed making pellets, do not close the pellet machine down simultaneously. Add some blended oil and biomass products to the pellet machine as well as let it run for 1-2 min. By doing this, we can load the die holes with oil mixture, to make sure that we can straight begin making pellets the following time. With this procedure, we can not just keep the mold, yet likewise conserve time. When the pellet machine quits, loosen up the adjusting screw as well as eliminate the left materials.



The maintenance of roller, die, shafts and also transmission

You need to eliminate all hard things and also metal blocks in resources before feeding them into the pellet machine, or they would create damage to the roller, die or major shaft. You can mount a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can reach up to 80 ℃, and the roller maintains high pressure during operation. As there is no dirt guard in the pellet machine, so you need to tidy up the bearing every 2-5 hours, as well as oil it with oil. After every 8 functioning hrs, the primary shaft demand to be fueled oil. The gearbox requirement cleaning every half a year. If there is irregular high warmth in the gearbox, you can use much better gear oil and enhance the clearance between the equipments for upkeep. The securing screw in the transmission component likewise require to be changed routinely.



Exactly how to change roller and die?

When the rollers wears, you can change the roller shell or the whole set of roller. If the bearing get loose or locked, you require 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 change it with a new one. If the ring die is taken care of with screws, you require to shake the ring die delicately, and remove the screw with also strength.




In flat die pellet machine, the level die is mounted with preserving nuts in the keyway. On the 2 sides of the level die, there are 2 symmetrical screw openings. You can use the screw motorist to press them out, or make use of a magnet to pull them out. During your pressing or drawing, maintain the flat die vibrating with a hammer, to make sure that the screw won't embeded the screw hole.



Security of the drive engine

Pick the matched power according to the needed manufacturing. If the power is not enough, the production will certainly be reduced as well as the pelletizing result is poor. If the power is too huge, it will take in even more power, speed up the fatigue, and also reduce the life span of roller as well as die.



The examination as well as repair need to be executed in power off condition. The machine ought to be placed near the working area, so regarding minimize the relocating time as high as feasible. Protect it from water logging, rainfall, electric leak, fire, etc.



Only when we make use of the pellet machine effectively and also keep it frequently can we maximize the pellet machine and lengthen its functioning life.
