Exactly how to utilize and preserve timber pellet machine effectively?<br>
Grinding before using

Most roller and also level dies in pellet machine are refined by high-heat treatment. After planing, boring, milling, and also relieving process, there are usually several cloths inside the die openings, which might affect the pelletizing results and also manufacturing. Consequently, prior to beginning a new pellet machine, or after changing a brand-new die, you require to grind it completely.



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



For ring die pellet mill, the grinding process requires even more oil mixture as well as longer time. The quantity of oil mixture is 10% that of pellet production per hour. The grinding time is 30-50 min. As well as the clearance between ring die and also the roller is 0.1-0.4 mm.



Pretreatment of basic materials

The appropriate moisture web content of biomass products must in between 14% as well as 20%. Dry products are upsetting shape, damp products will make the pellets loose. The dimension of the raw materials need to be less than the hole size of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm as well as 8mm, and the size of raw materials ought to be under 5mm, or they may obstruct the holes as well as reduce pellet production.



The glue pressure establishes the developing price of the pellets Most biomass materials contain lignin, which would melt under high temperature and also act as binder. But some products like rice husk has low sticky force. It require to be combined with sawdust or binders to make pellets




The density and also length of the wood pellets.

The density of wood pellets is established by the hole size of the die. The size is determined by the slicer. In level die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. about his of them can be adjusted to accomplish various sizes. For your own usage, it is far better to be brief. For transportation and also selling, it suggest to be a little long.



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



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

When you completed making pellets, don't shut the pellet machine down at the same time. Include some mixed oil as well as biomass products to the pellet machine and let it run for 1-2 min. richi pellet , we can load the die holes with oil combination, so that we can directly start making pellets the following time. With this process, we can not only maintain the mold and mildew, but likewise conserve time. When the pellet machine stops, loosen the adjusting screw and also clear away the left materials.



The upkeep of roller, die, shafts and transmission

You ought to get rid of all difficult things as well as metal blocks in basic materials before feeding them right into the pellet machine, or they would trigger damages to the roller, die or major shaft. You can set up 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 protector in the pellet machine, so you require to clean up the bearing every 2-5 hours, as well as lubricate it with oil. After every 8 functioning hours, the main shaft requirement to be oiled. The transmission demand cleaning every half a year. If there is https://extruschuler.com/floating-fish-feed-making-machine-plant/ in the transmission, you can make use of better equipment oil as well as boost the clearance between the equipments for maintenance. The securing screw in the transmission part likewise need to be replaced regularly.



Exactly how to replace roller as well as die?

When the rollers breaks, you can replace the roller shell or the whole set of roller. If the bearing get loose or locked, you require to change the bearing and even the shaft.




In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart and also replace it with a brand-new one. If the ring die is repaired with screws, you need to tremble the ring die delicately, as well as get rid of the screw with even toughness.



In flat die pellet machine, the flat die is installed with retaining nuts in the keyway. On the 2 sides of the flat die, there are 2 balanced screw openings. You can make use of the screw motorist to press them out, or use a magnet to pull them out. Throughout your pushing or pulling, keep the level die shaking with a hammer, so that the screw will not stuck in the screw opening.



Defense of the drive engine

Choose the matched power according to the required manufacturing. If the power is insufficient, the manufacturing will be reduced as well as the pelletizing impact is poor. If the power is too big, it will take in more power, speed up the weariness, and shorten the life span of roller and also die.



The examination as well as repair work should be performed in power off condition. The machine needs to be put near the working area, so regarding minimize the relocating time as long as possible. Safeguard it from water logging, rain, electric leakage, fire, etc.



Only when we make use of the pellet machine correctly and also maintain it on a regular basis can we take full advantages of the pellet machine as well as extend its working life.
