Just how to make use of and also preserve timber pellet machine effectively?<br>
Grinding prior to utilizing

Many roller as well as flat dies in pellet machine are processed by high-heat therapy. After planing, boring, milling, and also relieving procedure, there are usually many dustcloths inside the die openings, which may influence the pelletizing impacts and manufacturing. For that reason, prior to beginning a new pellet machine, or after changing a new die, you need to grind it extensively.



We utilize oil mix to refine grind the roller as well as level die. The oil mix is composed of 20% fine sand, 65% biomass materials( like sawdust), 15% waste engine oil. Before feeding the oil mixture to the pellet machine, you must change the clearance 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 even more oil combination as well as longer time. The amount of oil combination 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 resources

The ideal dampness web content of biomass materials must between 14% and 20%. Dry products are upsetting shape, wet materials will make the pellets loose. The size of the raw materials must be less than the hole size of pellet mill dies. Generally, the hole dimension of the pellet mill die is 6mm as well as 8mm, and also the dimension of resources ought to be under 5mm, or they might obstruct the holes and minimize pellet manufacturing.



The adhesive force determines the creating price of the pellets Many biomass materials consist of lignin, which would melt under heat and serve as binder. However Richi machinery like rice husk has reduced glue pressure. It require to be blended with sawdust or binders to make pellets



The density and also size of the wood pellets.

The thickness of wood pellets is established by the opening dimension of the die. The length is identified by the slicer. In level die pellet machine, the slicer is mounted under the level die, while in ring die pellet machine, the slicer is set up outside the ring die. Both of them can be adjusted to attain different dimensions. For your very own use, it is far better to be brief. For transportation as well as marketing, it advise to be a little long.





After the wood pellets come out from the pellet machine, they are hot with some heavy steams. They can be dried and cooled down in an open field, or by a counter-flow cooler. Quick cooling down can boost the hardness of the timber pellets, and facilitate storage and also transport.



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

When you finished making pellets, don't shut the pellet machine down simultaneously. Add some blended oil and also biomass materials to the pellet machine as well as allow it compete 1-2 minutes. This way, we can fill the die openings with oil mixture, so that we can directly start making pellets the following time. With this procedure, we can not just preserve the mold, however additionally conserve time. When the pellet machine stops, loosen up the readjusting screw as well as eliminate the left products.



The maintenance of roller, die, shafts and gearbox

You must get rid of all hard items and steel blocks in basic materials prior to feeding them 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 hopper.



The heat inside the pelletizing chamber can rise to 80 ℃, and also the roller maintains high pressure during operation. As there is no dirt protector 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 irregular high warmth in the transmission, you can use far better equipment oil as well as increase the clearance between the equipments for maintenance. The fastening screw in the transmission part likewise need to be changed regularly.



Just how to replace roller and also die?

When the rollers wears, you can replace the roller covering or the entire collection of roller. If the bearing get loosened or secured, you require to change the bearing and also the shaft.



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



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



Defense of the drive engine

Select the matched power according to the required manufacturing. If fish feed pellet machine is inadequate, the manufacturing will certainly be low and the pelletizing impact is poor. If the power is as well large, it will take in more power, accelerate the weariness, and shorten the life span of roller and also die.



The examination as well as repair service must be performed in power off problem. The machine needs to be put near the working area, so as to lower the relocating time as long as possible. Protect it from water logging, rain, electrical leak, fire, etc.



Only when we use the pellet machine appropriately and maintain it consistently can we maximize the pellet machine and lengthen its working life.
