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


The majority of roller and flat dies in pellet machine are processed by high-heat treatment. After planing, boring, milling, as well as appeasing procedure, there are usually several rags inside the die holes, which might affect the pelletizing impacts and manufacturing. As a result, prior to starting a brand-new pellet machine, or after replacing a brand-new die, you need to grind it completely.



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



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



Pretreatment of resources

The ideal dampness web content of biomass materials need to between 14% and 20%. Dry materials are hard to take shape, wet products will certainly make the pellets loose. fish pellet machine of the raw materials should be less than the hole size of pellet mill dies. Usually, https://richimachineryblog.wordpress.com/2023/03/15/straw-rice-husk-utilized-for-biomass-pellet-mill/ of the pellet mill die is 6mm and also 8mm, and also the dimension of raw materials need to be under 5mm, or they may obstruct the holes as well as lower pellet manufacturing.



The sticky force identifies the creating rate of the pellets Most biomass products contain lignin, which would certainly melt under high temperature as well as work as binder. Yet some products like rice husk has low sticky pressure. It require to be combined with sawdust or binders to make pellets



The density and size of the timber pellets.

The thickness of timber pellets is identified by the opening dimension of the die. The length is figured out 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 adjusted to attain various dimensions. For your very own usage, it is far better to be short. For transportation as well as selling, it recommend to be a little lengthy.



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



Do not close down the machine right after making pellets.

When you finished making pellets, don't close the pellet machine down at the same time. Add some mixed oil as well as biomass materials to the pellet machine and also let it compete 1-2 min. This way, we can load the die holes with oil combination, so that we can straight start making pellets the following time. With this procedure, we can not only keep the mold and mildew, however likewise conserve time. When the pellet machine quits, loosen the adjusting screw as well as clear away the left products.



The upkeep of roller, die, shafts as well as gearbox

You must remove all difficult items and steel blocks in resources before feeding them into the pellet machine, or they would certainly create damages to the roller, die or major shaft. You can set up a tubular magnet on the feed receptacle.



The warmth inside the pelletizing chamber can reach up to 80 ℃, and also the roller maintains high pressure during operation. As there is no dirt guard in the pellet machine, so you need to tidy up the bearing every 2-5 hrs, and also lubricate it with oil. After every 8 working hours, the primary shaft need to be oiled. The transmission need cleaning every half a year. If there is abnormal high heat in the gearbox, you can use far better gear oil and increase the clearance in between the gears for maintenance. The attaching screw in the transmission component likewise need to be changed regularly.



How to change roller and die?

When the rollers wears, you can change the roller covering or the whole set of roller. If the bearing get loosened or locked, you need to replace the bearing and also even 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 brand-new one. If the ring die is taken care of with screws, you require to shake the ring die gently, and remove the screw with also strength.



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 holes. You can utilize the screw chauffeur to press them out, or utilize a magnet to pull them out. Throughout your pressing or drawing, maintain the level die shaking with a hammer, to make sure that the screw won't embeded the screw opening.



Defense of the drive engine

Pick the matched power according to the necessary manufacturing. If the power is not nearly enough, the manufacturing will be reduced and the pelletizing result is poor. If the power is too large, it will eat even more power, increase the weariness, and also reduce the life span of roller and die.



The test and repair service need to be accomplished in power off problem. The machine must be positioned near the functioning area, so as to minimize the moving time as high as feasible. Safeguard it from water logging, rainfall, electric leakage, fire, etc.



Only when we use the pellet machine properly and also preserve it consistently can we maximize the pellet machine and extend its working life.
