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

The majority of roller and also flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, and also quenching procedure, there are normally several cloths inside the die holes, which might influence the pelletizing results and also production. Consequently, prior to starting a new pellet machine, or after changing a brand-new die, you need to grind it completely.



We use oil blend to process grind the roller and level die. The oil blend is made up of 20% fine sand, 65% biomass materials( 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 also flat die to 0.1-0.3 mm. The grinding procedure needs to last 15-40 minutes.



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



Pretreatment of raw materials

The appropriate moisture content of biomass materials need to in between 14% and also 20%. Dry products are hard to take shape, damp materials will certainly make the pellets loose. The size of the raw products must be less than the hole size of pellet mill dies. Normally, the hole size of the pellet mill die is 6mm and 8mm, and also the size of raw materials should be under 5mm, or they might obstruct the holes and reduce pellet manufacturing.



The adhesive force determines the forming rate of the pellets The majority of biomass materials contain lignin, which would melt under high temperature and also function as binder. However some materials like rice husk has reduced glue pressure. It need to be mixed with sawdust or binders to make pellets



The thickness and also size of the timber pellets.

The thickness of timber pellets is established by the hole size of the die. The size is figured out by the slicer. In rabbit pellet making machine , the slicer is installed under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. small poultry feed machine of them can be adapted to achieve various dimensions. For your very own use, it is much better to be short. For transportation and also 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 out as well as cooled in an open area, or by a counter-flow colder. Quick cooling can enhance the hardness of the wood pellets, and also facilitate storage and also transport.



Don't shut down the machine right after making pellets.

When you finished making pellets, do not close the pellet machine down simultaneously. Include some blended oil as well as biomass materials to the pellet machine and allow it run for 1-2 minutes. In this way, we can load the die holes with oil mixture, so that we can directly begin making pellets the next time. With this procedure, we can not just keep the mold and mildew, however also conserve time. When the pellet machine stops, loosen up the adjusting screw and remove the left products.



The maintenance of roller, die, shafts and transmission

You ought to get rid of all tough things as well as metal blocks in raw materials before feeding them right into the pellet machine, or they would certainly trigger damages to the roller, die or major shaft. You can set up a tubular magnet on the feed hopper.



The warm inside the pelletizing chamber can rise to 80 ℃, and also the roller sustains high pressure throughout procedure. As there is no dust protector in the pellet machine, so you require to tidy up the bearing every 2-5 hours, and also lubricate it with oil. After every 8 working hrs, the major shaft demand to be fueled oil. The gearbox requirement cleansing every half a year. If there is abnormal high warm in the gearbox, you can make use of much better gear oil and raise the clearance between the gears for maintenance. The securing screw in the transmission component likewise require to be replaced consistently.



Exactly how to replace roller as well as die?

When the rollers wears, you can replace the roller covering or the whole set of roller. If small pellet machine obtain loosened or locked, you require to change the bearing and even the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and also change it with a brand-new one. If the ring die is fixed with screws, you need to tremble the ring die gently, and also get rid of the screw with also toughness.



In level die pellet machine, the flat die is installed with keeping nuts in the keyway. On the 2 sides of the level die, there are 2 symmetrical screw holes. You can utilize the screw chauffeur to push them out, or use a magnet to pull them out. During your pushing or pulling, maintain the level die shaking with a hammer, so that the screw will not stuck in the screw hole.




Security of the drive engine

Pick the matched power according to the necessary production. If the power is insufficient, the manufacturing will certainly be low and also the pelletizing impact is poor. If the power is too huge, it will certainly eat more power, increase the fatigue, and shorten the life span of roller and die.



The examination and fixing need to be accomplished in power off condition. The machine needs to be placed near the functioning place, so as to reduce the moving time as high as possible. Secure it from water logging, rainfall, electric leakage, fire, and so on.



Only when we use the pellet machine correctly and keep it on a regular basis can we maximize the pellet machine and prolong its functioning life.
