Just how to use as well as maintain timber pellet machine properly?<br>
Grinding prior to using

A lot of roller as well as flat dies in pellet machine are refined by high-heat therapy. After planing, drilling, milling, and satiating procedure, there are usually numerous cloths inside the die openings, which might influence the pelletizing impacts and manufacturing. As a result, before beginning a brand-new pellet machine, or after replacing a brand-new die, you require to grind it completely.



We make use of oil mix to refine grind the roller and also level die. The oil blend is made up of 20% fine sand, 65% biomass products( like sawdust), 15% waste engine oil. Prior to feeding https://carmenrichi.bloggersdelight.dk/2023/03/13/ high-efficiency-…eed-making-maker to the pellet machine, you ought to adjust the clearance between roller and also level die to 0.1-0.3 mm. The grinding procedure should last 15-40 minutes.



For ring die pellet mill, the grinding procedure needs more oil blend and longer time. The amount of oil mixture is 10% that of pellet production per hour. The grinding time is 30-50 minutes. As well as the clearance in between ring die and the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The appropriate dampness web content of biomass materials ought to between 14% and 20%. Dry materials are upsetting shape, damp products will make the pellets loose. The size of the raw products ought to be less than the hole dimension of pellet mill dies. Generally, the hole size of the pellet mill die is 6mm as well as 8mm, and also the dimension of resources ought to be under 5mm, or they might block the holes as well as decrease pellet manufacturing.



The adhesive force determines the forming rate of the pellets Many biomass products include lignin, which would certainly thaw under high temperature and function as binder. However some products like rice husk has reduced glue pressure. It require to be mixed with sawdust or binders to make pellets



The thickness and also length of the wood pellets.

The thickness of timber pellets is identified by the hole dimension of the die. The length is identified by the slicer. In level 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 adjusted to attain various sizes. For your own use, it is much better to be short. For transportation as well as selling, it recommend to be a little long.



After the timber pellets come out from the pellet machine, they are hot with some heavy steams. They can be dried and cooled down in an open field, or by a counter-flow cooler. Quick cooling can boost the solidity of the timber pellets, and promote storage and also transport.




Do not shut down the machine right after making pellets.

When you completed making pellets, don't close the pellet machine down at the same time. Include some combined oil as well as biomass products to the pellet machine as well as let it run for 1-2 minutes. By doing this, we can fill up the die holes with oil blend, to ensure that we can straight begin making pellets the next time. With this procedure, we can not just maintain the mold, however likewise save time. When the pellet machine stops, loosen up the adjusting screw and eliminate the left products.



The upkeep of roller, die, shafts and also transmission

You should remove all hard things and also metal blocks in resources 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 hopper.



The heat inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure throughout procedure. As there is richi pellet machine in the pellet machine, so you need to clean up the bearing every 2-5 hours, and lube it with oil. After every 8 functioning hours, the primary shaft demand to be oiled. The transmission need cleansing every half a year. If there is irregular high warmth in the gearbox, you can use much better equipment oil and enhance the clearance in between the equipments for maintenance. The securing screw in the transmission component likewise need to be replaced routinely.



Exactly how to replace roller and also die?

When the rollers breaks, you can change the roller covering or the whole collection of roller. If the bearing get loosened or secured, you need to change the bearing as well as also the shaft.



In ring die pellet machine, just loosen up the hoop chuck, take the old ring die apart and change it with a new one. If the ring die is taken care of with screws, you require to drink the ring die gently, as well as eliminate the screw with even toughness.



In flat die pellet machine, the flat die is installed with preserving nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw holes. You can use the screw vehicle driver to push them out, or utilize a magnet to draw them out. Throughout your pressing or drawing, maintain the level die shaking with a hammer, to make sure that the screw will not stuck in the screw opening.



Protection of the drive engine

Choose the matched power according to the needed manufacturing. If the power is not enough, the production will certainly be low and also the pelletizing impact is poor. If the power is also huge, it will certainly consume more power, speed up the fatigue, as well as shorten the life span of roller and die.



The examination and repair should be performed in power off condition. The machine needs to be placed near the functioning area, so regarding decrease the relocating time as much as feasible. Protect it from water logging, rainfall, electric leakage, fire, etc.



Only when we make use of the pellet machine correctly and maintain it consistently can we maximize the pellet machine as well as extend its working life.
