Description

Technical Field

[0001] The utility model relates to the technical field of papermaking additives, and specifically relates to a papermaking additive drying and crushing structure. Background Art

[0002] Papermaking additives are widely used in the papermaking industry. Their main function is to improve the quality of paper, including improving the strength, glossiness, smoothness, dry-wet stability, etc. Papermaking additives can be used for various types of paper, such as newsprint, coated paper, wrapping paper, etc. In addition, papermaking additives can also be used for mixing and filtering pulp, improving the production efficiency of paper machines and paper quality. Papermaking additives are a type of chemical substance with a wide variety of different formulas. They are generally composed of a variety of chemical substances. These chemical substances will undergo chemical changes during storage due to environmental factors such as temperature, humidity, and oxygen, causing the product to become hard, brittle, and lose fluidity, resulting in dryness and agglomeration.

[0003] If the dried and agglomerated papermaking additives are not treated, it will have a lot of impact on the subsequent processing. Untreated dried and agglomerated papermaking additives will affect the quality of paper, such as strength, smoothness, water absorption, etc., resulting in a decrease in paper performance. In the papermaking industry, dried and agglomerated papermaking additives should be treated in time. Therefore, we propose a papermaking additive drying and crushing structure to ensure the quality of paper during the papermaking process. Utility Model Content
