In the first stage, the straw briquettes are relatively loose and require a small amount of pressure to achieve a large proportion of deformation. The relationship between pressure and deformation in this process can be approximated as a linear relationship. The compression process of the straw briquetting machine is mainly to reduce the gap between the briquettes. Because the straw itself is relatively loose, the compression volume at this stage is relatively large. Easy to complete.
The next stage is mainly compact. After the previous stage of compression, the density between the straw briquettes decreases, and more compression is required to achieve more compression. The deformation amplitude of the straw becomes smaller, but the pressure needs to increase more quickly. The relationship between material deformation and pressure is linear in length. At this stage, the pressure of the straw briquetting machine is mainly to overcome the gaps inside the straw. The compressed packing at this stage is significantly affected by moisture content, feed rate and loading speed.
