Paragraph starter
This study demonstrates that operational parameters of a processing machine, such as screen aperture size and rotational speed, can be adjusted to control the particle size distribution of the output material and influence overall productivity. For instance, a specific screen size was found to yield a high percentage of uniform sawdust, while productivity and power consumption varied significantly with material moisture content and machine speed, highlighting the importance of parameter optimization in waste valorization processes.
