The production of wood pellets.
I hope that it will be interesting for you to find out something interesting about the technology of wood pellet production. In general, the technological process of production of wood pellets includes the following stages.
Let’s begin with filing and storage of raw materials. In most cases the land storage of raw materials is organized in such a way to ensure the constant flow of this stuff for the further processing. The equipment includes the separation unit and the transport system, which can be made in various ways.
The next stage is closely connected with shredding. At this stage of raw material preparation wood chips, sawdust, bark, shavings are fed to the shredder. It goes without saying that the supplied material can be of varied moisture content but anyway it must not contain any foreign matter such as stones, metal, sand and so on. In the amount of raw material bark, needles, leaves should not exceed 17% of the total mass due to high ash content.
Now it’s high time to start drying this stuff with the help of special machinery. On this stage our
crushed raw material gets in the drying chamber of the special unit. By the way it’s possible to remove the excessive moisture by the hot air. The heat - generator can operate both on the same waste as mentioned above and gas.
Then this crushed and dried product enters the special box where the separation of the dried material and cooling is carried out. Then the dried material is fed to the power supply device and the pellet making process goes on.
The the process of granulation should be carried out. To cut a long story short I can say that this shredded and dried wood waste gets into the rotating matrix with holes of 6-10 mm in diameter. There the high pressure is created due to the passage of the product through the matrix which is rotating on eccentric axes of rollers.
Then it’s time to cool this stuff properly. Through the special outlet ready made wood pellets fall into a special device. I mean a special cooling conveyor, where there cooling and cleaning of wood pellets from the fine fraction is carried out.
The fine fraction is fed back into the bunker and as the result of it the whole pellet making process goes on in the mode of non – waste and non - stop. Then purified and cooled pellets fall into the container for packaging and transporting to the storage or just come into a large reservoir.
Of course you know that the last procedure is packaging. With the feeder, designed for automatic weighing, ready made wood pellets are packed in large bags or polypropylene bags weighing 30-40 kg. Now wood pellets are ready to heat you.
Among many energy saving alternatives, we highly recommend you to learn more about wood pellets.
This is a short list of advantages of using wood pellets. They are not sophisticated; they do not need huge investments into fancy equipment; they are ecological in the heart of it. Please invest 5 minutes of your time into learning more about wood pellets - it is really vital now.
