Description

Technical Field

[0002] A pulp fiber separator is a device used in the papermaking process to separate the fibers from other components (such as heavy and light impurities) in the raw material. This process is crucial to improving pulp quality and production efficiency because it ensures the purity and uniformity of the fibers while removing non-fibrous materials that may affect paper properties.

The discharged waste residue must also be reprocessed, the process is very complicated, and the power consumption is too high. In the separation process, the high-speed rotating components may damage the fibers. In particular, in the mechanical separation process, the length and strength of the fibers may be affected, thereby reducing the quality of the final product.
