10 Panguna nga mga Rason Ngano nga Ang Imong Pellet Machine Dili Pag-discharge ug Ubos nga Kapasidad

Why doesn’t the makina sa pellet discharge anymore?

What are the reasons why the pellet machine low capacity?

Let’s talk about these issues today: pellet machine troubleshooting.

Many customers who are making pellets for the first time will have various problems after purchase. Pananglitan, ang biomass pellet machine dili makahimo og mga pellets, ug ang output nga kapasidad sa pellet machine katunga lamang sa gipahayag nga kapasidad. Karon, ipakita namo kanimo ang 10 nag-unang rason alang niini nga mga problema sa biomass pellet machine, hinaot makatabang ni nimo.

Sa dili pa nimo ipakita kanimo ang mga hinungdan, atong hisgotan kon sa unsang paagi ang wood pellet machine pagproseso. Ang nag-unang rason ngano nga ang biomass pellet machine mahimong maporma mao nga ang friction tali sa pressing roller ug sa agup-op makamugna kainit., aron ang lignin sa mga chips sa kahoy mahimong bug-os nga buhian sa usa ka natural nga binder sa temperatura nga 80-90 °, so that even without any adhesive the pellets can be shaped. After knowing this ,let’s talk about the main reason for the wood pellet problems :

First time use with new makina sa kahoy nga pellet ring die

The first time use, the wood pellet machine ring die hole has a poor finish. The drilling has burrs, so the friction of the discharge is large, which is easy to cause no discharge or less discharge, so it needs to be polishing and grinding. After mixing with sand, mga tipak sa kahoy, and industrial waste machine oil, the sand is 30 %. Mix 60% wood chips and 10% oil to grind the biomass pellet machine.

Material accumulation in the makina sa pellet

After the pellet machine finish working, there will be some accumulations, and there will be no clean residue. After the next day the pellet machine continue working, due to the high temperature, it will solidify into a hard block, so the pellet machine cannot discharge normally. The solution is to clean the inside and clean up the residue.

Unstable working voltage

The motor of the wood pellet machine needs a certain voltage to operate normally. If the voltage is too low, even if the motor can roll, the power generated by it is not enough to quickly extrude the material in the compression chamber. Niining panahona, there will be a lot of materials blocked in the compression cavity, affecting production.

Inappropriate distance between the wood pellet mill ring die and the pressure roller

wood pellet mill ring die and the pressure roller

The pellet machine makes pellets through the extrusion of the accessory roller and the ring die. If the distance is not appropriate, the pellet machine will not be able to discharge normally. The solution is to adjust the distance properly. When the equipment is tested, the technical staff of the pellet machine manufacturer will teach the customer how to use and debug, so as to avoid the situation of non-discharge.

After a period of production of the biomass pellet machine, tungod sa friction tali sa sawdust ug sa die press roller, ang gintang tali sa ring die ug sa press roller kinahanglan nga i-adjust sa husto. Kung gamay ra ang distansya, ang press roller makadugang sa friction sa ring die ug mub-an ang oras sa paggamit sa ring die. Ang asembliya magpahinabo nga ang press roller nga madulas ug dili hapsay ang pag-discharge, nga nagpamenos sa output; sa kinatibuk-ang pagsulti, ang gintang tali sa singsing mamatay ug ang press roller anaa sa taliwala 0.1 ug 0.3mm. Kasagaran, the new press roller and the new ring die are suitable Use a slightly larger gap. The old pressure roller and the old ring die should be matched with a smaller gap. The ring die with large aperture should use a slightly larger gap, and the ring die with small aperture should use a slightly smaller gap, which is easy to granulate. Large gaps should be used, and small gaps should be used for materials that are difficult to granulate. For the operator, it is necessary to have actual operating experience and be able to skillfully select and adjust the ring die gap.

Material moisture is inappropriate

For the biomass pellet machine, the raw material moisture is too high or too low will affect the quality of the pellets greatly. Too much or too little moisture in the material will cause the die hole to be blocked, causing the pellet machine to fail to discharge. Because the biomass pellet machine is elegantly shaped by physical pressing, its adhesiveness is formed by a combination of appropriate moisture and pressing, without any addition of chemical ingredients. Busa, the moisture of the raw material is one of the important factors affecting the output of the biomass pellet machine. (It is recommended that the moisture of general raw materials should be controlled within 10-15%. If too wet, you need a makina sa sawdust dryer to remove the moisture .Of course, the specific situation still depends on the type of raw materials.

The ring die and the pressure roller are severely worn

The ring die and press roller are the main parts of the pellet machine, and they are also vulnerable parts. If the parts are aging or malfunction, these are also the reasons that the pellet machine will not discharge. If it is a newly purchased pellet machine, you only need to look at which part is not working to tell which is the problem. If it is a pellet machine that has been used for many years, it means that the parts are aging, just replace the parts.

Inappropriate ring die compression ratio

The ring die compression ratio is incorrect. For a biomass pellet machine, compression ratio and moisture are two equally important factors. One of them is controlled by the raw materials and the other is controlled by the ring die. Both are indispensable. Kung dili, the output of the biomass pellet machine will be seriously affected. Busa, before purchasing a biomass pellet machine, you must communicate with the manufacturer the compression ratio of the biomass pellet machine. Because different raw materials have different compression ratios, if you have multiple raw materials, you should communicate with the manufacturer to prepare a few more ring dies.

The material has high crude fiber content

Pellet machines have different models and powers. For different types of pellet machines, the requirements for pelleting are different. Some pellet machines are suitable for special pressing of coarse fibers, and some are suitable for special pressing of fine fibers. If your materials is too large, you need to use a fine galingan sa martilyo to reduce the size of your material. Kung gipili nimo ang usa ka gamay nga pellet machine aron ma-compress ang mga coarse fiber nga materyales, mao usab kini ang hinungdan ngano nga ang pellet machine dili mogawas. Ang solusyon mao ang pagpakigsulti sa tiggama ug pag-ilis sa usa ka pellet machine

Kakulang sa Lubricating Oil

Human sa taas nga panahon sa pagtrabaho ,ang pellet machine magkinahanglan ug igong lubricating oil para sa normal nga pagtrabaho ,kung dili ka makadugang sa igo nga lana ,dali ra mahurot ang mga spare parts, ug ang mga wood pellets dili mogawas sa maayong porma ,so every week ,the working staff should check the lubricating oil tank ,and add oil in time .

The ring die has been used for too long time and needs to be replaced

If the biomass pellet machine has been in normal production for a period of time and the output suddenly drops, then check whether the cone hole on the inner wall of the ring die is worn, whether the pressure roller is worn, and then check whether the ring die is out of round. Some inferior ring dies will have rough inner holes. The out-of-round ring die leads to unsmooth discharging, uneven particles, difficult discharging, and low output; it also causes the granulator to work weakly, the current is unstable, and the output is reduced.
