Pelletizer Machine-Drying Conclusions

Other than a pelletizer machine, a dryer can be the largest capital expenditure on a pelletizer plant. Drying systems are heavy and also take up quite a lot of space. Sourcing dry raw materials saves the costs of a drying system, and can dramatically reduce the production cost per tonne.

Due to the different characteristics of various raw materials, the pellet quality is unequal. To improve the pellet quality or maximize the production capacity of pelletizer machine, you can add the binder (a kind of glue, e.g., vegetable oil or rapeseed cake) to help the lignin-lacked material to compress into pellets much easier by the biomass pelletizer machine.

Whether producing a single material pellet or a mixed material pellet, material consistence is crucial to a consistent, reliable and efficient pelletizer machine. Batch mixers are used after the material has been milled and dried (if required). Through mixing the material, a more consistent material blend is fed into the pelletizer. Mixing may occur before or after conditioning. The graphs below illustrate the possible effects of poor material consistency.
