What are the last two steps of the wood pellet production line?
| Model No. | Capacity(kg/h) | Power(kw) | Weight(t) |
| RKL-250 | 100-200 | 15 | 0.5 |
| RKL-300 | 150-250 | 22 | 0.65 |
| RKL-350 | 100-300 | 30 | 0.76 |
| RKL-400 | 300-600 | 37 | 2.2 |
| RKL-450 | 500-800 | 55 | 4.3 |
| RKL-550 | 1000-1500 | 90 | 5.5 |
Cooling and Screening
- Once the pellets are formed, they are hot and soft. They need to be cooled down to room temperature to harden and increase their strength. A cooling unit, such as a counter - flow cooler, is used for this purpose. After cooling, the pellets are screened again. This second screening is to separate any under - sized or over - sized pellets, as well as any un - pelleted material. The qualified pellets are then ready for further packaging.
Packaging and Storage
- The final step in the wood pellet production line is packaging. The high - quality pellets are usually packed in bags of various sizes, such as 20kg or 25kg bags, for easy handling and transportation. They can also be bulk - loaded into trucks or containers for large - scale distribution. Proper storage is also crucial. The pellets should be stored in a dry and well - ventilated area to prevent moisture absorption, which could lead to mold growth and a decrease in the calorific value of the pellets.
