Exactly how to use and also maintain wood pellet machine correctly?<br>
Grinding before making use of

Most roller and level dies in pellet machine are processed by high-heat treatment. After planing, drilling, milling, as well as satiating process, there are generally many dustcloths inside the die holes, which might influence the pelletizing results as well as production. Consequently, prior to beginning a new pellet machine, or after replacing a new die, you need to grind it extensively.



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



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



Pretreatment of resources

The ideal wetness content of biomass products must between 14% and also 20%. Dry materials are upsetting form, damp materials will certainly make the pellets loose. The dimension of the raw products must be less than the hole dimension of pellet mill dies. Typically, the hole size of the pellet mill die is 6mm and 8mm, and the size of basic materials should be under 5mm, or they might obstruct the holes as well as decrease pellet production.



The sticky force determines the forming rate of the pellets A lot of biomass products consist of lignin, which would melt under high temperature as well as act as binder. However some materials like rice husk has low adhesive pressure. It require to be mixed with sawdust or binders to make pellets




The thickness and size of the wood pellets.

The density of timber pellets is established by the opening size of the die. The length is figured out by the slicer. In level die pellet machine, the slicer is installed under the flat die, while in ring die pellet machine, the slicer is mounted outside the ring die. Both of them can be adjusted to accomplish different dimensions. For your very own use, it is much better to be brief. For transport as well as selling, it recommend to be a little lengthy.



After the wood pellets appear from the pellet machine, they are hot with some heavy steams. They can be dried as well as cooled down in an open area, or by a counter-flow cooler. Quick cooling can boost the solidity of the wood pellets, and also assist in storage space as well as transportation.



Do not close down the machine right after making pellets.

When you completed making pellets, don't shut the pellet machine down at once. Include some mixed oil as well as biomass products to the pellet machine and allow it compete 1-2 min. In this way, we can load the die holes with oil mixture, to ensure that we can directly begin making pellets the following time. With Richi machine , we can not just keep the mold, but also conserve time. When the pellet machine quits, loosen the adjusting screw and also clear away the left materials.



The maintenance of roller, die, shafts and gearbox

You must eliminate all tough things and also metal blocks in basic materials prior to feeding them right into the pellet machine, or they would certainly cause damage to the roller, die or main shaft. You can mount a tubular magnet on the feed receptacle.



The heat inside the pelletizing chamber can rise to 80 ℃, and also the roller sustains high pressure throughout operation. As there is manure pellet machine in the pellet machine, so you require to tidy up the bearing every 2-5 hours, as well as lubricate it with oil. After every 8 working hrs, the major shaft demand to be fueled oil. The gearbox demand cleansing every half a year. If there is uncommon high warmth in the transmission, you can use much better equipment oil and raise the clearance between the gears for maintenance. The securing screw in the transmission part additionally require to be changed on a regular basis.



How to change roller and die?

When the rollers breaks, you can replace the roller covering or the whole collection of roller. If the bearing obtain loose or secured, you need to change the bearing and also even the shaft.



In ring die pellet machine, simply loosen the hoop chuck, take the old ring die apart and also change 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 also get rid of 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 level die, there are 2 in proportion screw holes. You can make use of the screw chauffeur to press them out, or make use of a magnet to draw them out. During your pressing or pulling, keep the level die vibrating with a hammer, to make sure that the screw will not embeded the screw hole.



Security of the drive engine

Choose the matched power according to the needed manufacturing. If the power is inadequate, the manufacturing will be low and the pelletizing impact is poor. If the power is too huge, it will certainly take in more power, increase the exhaustion, as well as shorten the life span of roller as well as die.



The examination and fixing need to be accomplished in power off problem. The machine needs to be positioned near the working place, so regarding reduce the moving time as long as feasible. Safeguard it from water logging, rainfall, electric leak, fire, etc.



Just when we utilize the pellet machine effectively as well as maintain it routinely can we maximize the pellet machine and also lengthen its functioning life.
