Exactly how to utilize and preserve timber pellet machine correctly?<br>
Grinding prior to utilizing

Most roller as well as level dies in pellet machine are processed by high-heat therapy. After planing, drilling, milling, and relieving richi pellet machine , there are normally many rags inside the die openings, which might influence the pelletizing results as well as production. For that reason, prior to beginning a brand-new pellet machine, or after changing a new die, you require to grind it thoroughly.




We utilize oil mixture to process grind the roller as well as flat 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 mixture to the pellet machine, you ought to change the clearance in between roller and level die to 0.1-0.3 mm. The grinding process ought to last 15-40 min.



For ring die pellet mill, the grinding procedure calls for more oil mixture as well as longer time. The quantity of oil blend is 10% that of pellet manufacturing 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 suitable dampness material of biomass materials ought to in between 14% and 20%. Dry products are hard to take form, moist materials will make the pellets loose. The dimension of the raw products must be less than the hole size of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm and also 8mm, and also the dimension of raw materials must be under 5mm, or they might obstruct the holes as well as lower pellet production.



The sticky pressure identifies the developing price of the pellets A lot of biomass products contain lignin, which would certainly melt under heat and also work as binder. But some products like rice husk has reduced sticky force. It require to be mixed with sawdust or binders to make pellets



The thickness as well as size of the wood pellets.

The thickness of wood pellets is determined by the hole size of the die. The size is figured out by the slicer. In flat die pellet machine, the slicer is set up under the level die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to achieve various dimensions. For your own usage, it is better to be brief. For transport as well as marketing, it suggest to be a little long.



After the timber pellets appear from the pellet machine, they are warm with some heavy steams. They can be dried and also cooled in an open area, or by a counter-flow cooler. Quick cooling can boost the hardness of the wood pellets, and also help with storage and transportation.



Do not shut down the machine right after making pellets.

When you ended up making pellets, don't close the pellet machine down at once. Include some blended oil as well as biomass products to the pellet machine and allow it run for 1-2 minutes. This way, we can fill up the die holes with oil combination, so that we can straight start making pellets the following time. With this process, we can not just keep the mold, yet additionally save time. When the pellet machine stops, loosen up the changing screw and also clear away the left products.



The maintenance of roller, die, shafts and also gearbox

You should remove all hard items and metal blocks in resources before feeding them right into the pellet machine, or they would create damage to the roller, die or primary shaft. pellet forming machine can set up a tubular magnet on the feed receptacle.



The warm inside the pelletizing chamber can reach up to 80 ℃, as well as the roller sustains high pressure during procedure. As there is no dust guard in the pellet machine, so you require to tidy up the bearing every 2-5 hrs, and lube it with oil. After every 8 functioning hrs, the main shaft requirement to be fueled oil. The transmission requirement cleaning every half a year. If there is unusual high warm in the transmission, you can use better equipment oil and also enhance the clearance between the gears for maintenance. The securing screw in the transmission component also need to be replaced routinely.



How to replace roller and also die?

When the rollers wears out, you can replace the roller covering or the whole set of roller. If the bearing get loosened or locked, you need to replace the bearing as well as also the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart as well as replace it with a new one. If the ring die is fixed with screws, you require to drink the ring die carefully, as well as remove the screw with also 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 in proportion screw holes. You can utilize the screw chauffeur to press them out, or use a magnet to pull them out. During your pushing or drawing, maintain the level die shaking with a hammer, to ensure that the screw won't embeded the screw hole.



Security of the drive engine

Pick the matched power according to the required manufacturing. If the power is inadequate, the production will certainly be reduced and also the pelletizing result is poor. If the power is too large, it will take in more power, accelerate the exhaustion, as well as shorten the life span of roller as well as die.



The test and also repair service need to be accomplished in power off problem. The machine needs to be positioned near the functioning location, so regarding decrease the moving time as high as feasible. Shield it from water logging, rain, electric leakage, fire, etc.



Just when we use the pellet machine appropriately and also maintain it frequently can we make the most of the pellet machine and lengthen its working life.
