What should be paid special attention to when making biomass pellets?
① Different types of materials require different compression ratios. For example, the compression ratio required for poplar is between 1:6-1:7, the compression ratio required for larch is about 1:5, and the compression ratio required for larch is 1:8.2, or even higher. Therefore, it is necessary to do a good job of raw material research and verification in the early stage. The compression ratio of the same mold is fixed, that is, the same mold can only adapt to a certain type of raw material. If there are many types of raw materials, then multiple molds with different compression ratios are required, or multiple raw materials are mixed into a fixed raw material according to the size ratio of the provided amount. In this way, there is no need to match multiple sets of molds, only one set of molds with a fixed compression ratio is needed. The specific implementation method of this process is best communicated with the equipment manufacturer to determine and select the mold with the best compression ratio.
② The moisture content of the raw materials required in different environments will fluctuate up and down, which will cause the water vapor generated during the compression process to directly present a water mist state, thereby affecting the pelletizing effect. Therefore, it is necessary to have a good sense of moisture, and then fine-tune the moisture on this basis.
Through the above analysis, we have gained a general understanding of the production of biomass energy pellets. Turning waste into treasure, biomass energy pellets are well-deserved.
