Description

Technical Field

[0002] With the development of society, people are increasingly pursuing environmental protection in their daily lives, so the demand for paper products is increasing. Paper products are mostly made of pulp, and the quality of pulp has a great impact on the quality of the final product. Common types of impurities in pulp include wood chips, bark, sand, metal fragments, etc. The presence of impurities will affect the quality of the product, causing spots, roughness, unevenness, and other problems on the product, reducing the strength and durability of the product. Therefore, these impurities need to be screened and separated by a screening machine. Through impurity removal and separation, the quality of the pulp can be ensured and the interference of impurities can be reduced, so that the pulp-molded products can be uniform and smooth, ensuring the quality of the final product.
