Remarkable sale ce wood pellets making machine for long using life
Process of wood pellet making machine
It contains six sections:wood chipping section,drying section,crushing section,pelletizing section,cooling section,packing section.
1. Log chipping section of wood pellet making machine
2. Drying section of wood pellet making machine
The best moisture content to pelletizing is about 14 to 16%. Our new rotary dryer is made up of burning stove and main rotary dryer, which can realize to reduce the moisture from 50% to 10%, and save about 30% energy consumption .
Our burning stove is fueled by coal and wood material, which can save electricity consumption largely. If the users want to use the other fuel such as gas and electricity, one Burner is necessary, but the extra cost will be charged.
3. Crushing section of wood pellet making machine
Depending on the different input material, we fit out the suitable Crushing machines. If the raw material is big logs with diameter less 300mm or big timber cutter, our BX Series Chipping and Crushing Machine is your best choices; While SFSP series Hammer Mill is widely used to crush each kind of straw, wood chip, tree branch, bark and leftover bits from agricultural wastes. The best moisture content in the Crushing Process is less 20%, and the thickness of the wood chip is less 5mm. If the moisture of wood chips is more than 20%, please first dry the wood chips using drum dryer.
4. Pelletizing section
| Wood Pellet Mill is the most important equipment, which have the following features: |
| 1). This equipment use sawdust, crops straw (corn stalk, beanstalk, sorghum culm and cotton stalk, rape stalk,sunflower culm and peanuts seedling), the chaff, grass, shrubs, twigs, bamboo sawdust, bag asses as raw materials. |
| 2). The main transmission adopts two motors belt transmission, ring die adopt advanced fast discharge type. |
| 3). Adopt international advanced alloy steel ring die, long lifetime, pellets smoother, quality higher. |
| 4). The international advanced level of power transfer coupling, with novel structure, compact,security, low noise,low fault performance. |
| 5). High-energy permanent magnet absorb iron device. |
| 6). Adjustable cutting knife , more convenient and reliable. |
After the pelletizing process, the temperature of the wood pellet is about 60 to 80 degree, and the moisture content of the wood pellet is about 15%, so we need use Cooler to reduce about 3% to 4% moisture, so this wood pellet is easy to store. But considering the feedback from some foreign clients, the local climate is very humidity; They hope to cool the wood pellet with moisture 7 to 8%. In order to satisfy different needs from different clients, we provide certain cooler to customer.
After cooling, the wood pellet will not directly enter into the fuel process, avoiding the wood pellet affected with damp. The packing process is necessary. In this process, we adopt domestic best Packing Machine.
