Just how to use and also keep wood pellet machine correctly?<br>
Grinding prior to utilizing

The majority of roller and also flat dies in pellet machine are processed by high-heat treatment. After planing, boring, milling, and appeasing process, there are typically numerous cloths inside the die holes, which may affect the pelletizing effects and manufacturing. As a result, prior to starting a brand-new pellet machine, or after replacing a new die, you need to grind it thoroughly.



We make use of oil mix to refine grind the roller as well as 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 mix to the pellet machine, you need to readjust the clearance in between roller and level die to 0.1-0.3 mm. The grinding process needs to last 15-40 min.



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



Pretreatment of raw materials

The ideal wetness content of biomass products must in between 14% as well as 20%. Dry materials are hard to take shape, moist products will certainly make the pellets loose. The size of the raw products must be less than the hole dimension of pellet mill dies. Normally, the hole size of the pellet mill die is 6mm and also 8mm, and the size of basic materials must be under 5mm, or they might block the holes and reduce pellet manufacturing.



The glue force figures out the creating price of the pellets The majority of biomass products include lignin, which would melt under heat and also act as binder. But some materials like rice husk has low adhesive pressure. It require to be blended with sawdust or binders to make pellets



The density and length of the timber pellets.


The density of wood pellets is identified by the opening dimension of the die. The size is identified by the slicer. In level die pellet machine, the slicer is set up under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be gotten used to attain various sizes. For your own use, it is much better to be short. For transportation and selling, it suggest to be a little lengthy.



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 field, or by a counter-flow colder. Quick cooling down can boost the solidity of the timber pellets, and also promote storage as well as transport.



Do not shut down the machine right after making pellets.

When you ended up making pellets, do not close the pellet machine down simultaneously. Include see here now combined oil as well as biomass products to the pellet machine and also let it compete 1-2 min. In this way, we can fill the die holes with oil combination, so that we can directly start making pellets the following time. With this process, we can not just keep the mold and mildew, yet likewise conserve time. When the pellet machine quits, loosen the adjusting screw and also clear away the left products.



The maintenance of roller, die, shafts and also gearbox

You should eliminate all hard things and also metal blocks in resources prior to feeding them right into the pellet machine, or they would cause damages to the roller, die or major shaft. You can install a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can rise to 80 ℃, and the roller maintains high pressure during procedure. As there is no dust protector in the pellet machine, so you require to clean up the bearing every 2-5 hours, and lube it with oil. After every 8 functioning hours, the main shaft requirement to be oiled. The transmission need cleaning every half a year. If there is unusual high warmth in the gearbox, you can make use of much better equipment oil and also enhance the clearance in between the equipments for maintenance. The attaching screw in the transmission component also need to be replaced routinely.



How to change roller and also die?

When the rollers breaks, you can replace the roller covering or the entire set of roller. If the bearing get loose or locked, you require to replace the bearing as well as also the shaft.



In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart as well as change it with a new one. If the ring die is fixed with screws, you require to tremble the ring die carefully, and eliminate the screw with even strength.



In flat die pellet machine, the flat die is set up with maintaining nuts in the keyway. On the 2 sides of the flat die, there are two symmetrical screw openings. You can utilize the screw vehicle driver to push them out, or use a magnet to draw them out. Throughout your pressing or pulling, maintain the level die shaking with a hammer, to ensure that the screw will not embeded the screw opening.




Protection of the drive engine

Select the matched power according to the required manufacturing. If the power is not enough, the manufacturing will certainly be low and the pelletizing result is poor. If the power is also huge, it will consume more power, speed up the exhaustion, as well as reduce the life span of roller and also die.



The examination as well as repair service ought to be accomplished in power off condition. straw pellet machine for sale must be placed near the functioning area, so as to lower the moving time as high as feasible. Protect it from water logging, rainfall, electric leak, fire, and so on.



Only when we utilize the pellet machine effectively and keep it routinely can we take full advantages of the pellet machine and also prolong its functioning life.
