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

Many roller and flat dies in pellet machine are processed by high-heat treatment. After planing, boring, milling, and appeasing process, there are generally several cloths inside the die holes, which may influence the pelletizing impacts as well as manufacturing. As a result, before beginning a new pellet machine, or after replacing a new die, you need to grind it completely.



We make use of oil mix to refine grind the roller as well as level die. The oil blend is made up of 20% great sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil blend to the pellet machine, you need to adjust the clearance between roller as well as flat die to 0.1-0.3 mm. The grinding procedure ought to last 15-40 minutes.




For ring die pellet mill, the grinding process needs even more oil combination and also longer time. The quantity of oil mixture is 10% that of pellet production per hr. The grinding time is 30-50 min. And fish food making machine price between ring die and the roller is 0.1-0.4 mm.



Pretreatment of resources

The ideal moisture material of biomass products need to between 14% and 20%. Dry materials are hard to take shape, damp materials will certainly make the pellets loose. wood chip pellet machine of the raw products should be less than the hole dimension of pellet mill dies. Usually, the hole dimension of the pellet mill die is 6mm as well as 8mm, and also the size of resources should be under 5mm, or they may block the holes as well as decrease pellet manufacturing.



The adhesive force figures out the creating rate of the pellets A lot of biomass products have lignin, which would thaw under high temperature as well as function as binder. But some products like rice husk has low adhesive force. It require to be mixed with sawdust or binders to make pellets



The thickness and size of the wood pellets.

The density of wood pellets is identified by the opening size of the die. The length 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 installed outside the ring die. Both of them can be adapted to accomplish different dimensions. For your very own usage, it is much better to be short. For transportation as well as selling, it suggest to be a little lengthy.



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



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

When you ended up making pellets, don't shut the pellet machine down simultaneously. Add some mixed oil and biomass products to the pellet machine and let it compete 1-2 min. In this way, we can fill up the die holes with oil mix, so that we can straight begin making pellets the following time. With this process, we can not only keep the mold, yet additionally conserve time. When the pellet machine quits, loosen up the changing screw and eliminate the left materials.



The upkeep of roller, die, shafts and also gearbox

You must remove all hard objects and also steel blocks in raw materials before feeding them into the pellet machine, or they would certainly cause damages to the roller, die or main shaft. You can set up a tubular magnet on the feed hopper.



The warmth inside the pelletizing chamber can rise to 80 ℃, and the roller sustains high pressure throughout procedure. As there is no dirt protector in the pellet machine, so you need to clean up the bearing every 2-5 hours, and lubricate it with oil. After every 8 working hrs, the main shaft need to be oiled. The gearbox requirement cleansing every half a year. If there is unusual high heat in the gearbox, you can make use of far better equipment oil and increase the clearance between the gears for maintenance. The securing screw in the transmission part also need to be changed regularly.




Just how to change roller and also die?

When the rollers breaks, you can replace the roller shell or the whole collection of roller. If the bearing get loosened or locked, you require to change the bearing and also the shaft.



In ring die pellet machine, simply loosen up the hoop chuck, take the old ring die apart and change it with a brand-new one. If the ring die is taken care of with screws, you need to drink the ring die gently, and remove the screw with even strength.



In flat die pellet machine, the level die is installed with keeping nuts in the keyway. On the 2 sides of the level die, there are 2 balanced screw openings. You can utilize the screw driver to push them out, or use a magnet to pull them out. During your pushing or pulling, maintain the flat die shaking with a hammer, to ensure that the screw won't stuck in the screw opening.



Security of the drive engine

Select the matched power according to the required production. If the power is inadequate, the production will be reduced as well as the pelletizing effect is poor. If the power is as well huge, it will certainly eat more power, accelerate the exhaustion, and also reduce the life span of roller and die.



The exam and repair work should be performed in power off problem. The machine must be positioned near the functioning area, so regarding lower the relocating time as much as feasible. Secure it from water logging, rainfall, electrical leakage, fire, and so on.



Just when we make use of the pellet machine correctly as well as preserve it consistently can we maximize the pellet machine and lengthen its working life.
