Pulp mixing uniformity is the basic premise of stable batch paper quality, especially for mixed pulp production of wood pulp, straw pulp and recycled pulp. In the batching and mixing process of multiple pulp raw materials, different fibers have different density, length and suspension characteristics, resulting in uneven mixing, local single-fiber aggregation and layered separation. Unbalanced pulp mixing leads to inconsistent fiber distribution in finished paper, causing local strength difference, uneven thickness, unstable ink absorption and batch quality fluctuation. Serious mixing deviation will also trigger periodic paper breakage and defective rate rise in high-speed production. Most paper mills rely on mechanical stirring to improve mixing effect, but single stirring mode cannot eliminate fiber stratification and aggregation of different raw materials, and mixing dead zones always exist in the pulp tank, resulting in long-term unstable mixing quality. Shandong Ludao Energy Technology Co., Ltd. provides professional pulp mixing uniformity optimization solutions. By adjusting fiber suspension activity, eliminating fiber stratification and aggregation, and realizing multi-component fiber uniform fusion, we achieve microscopic uniform mixing of mixed pulp. The solution stabilizes fiber distribution structure of finished paper, eliminates local performance difference, unifies batch production indicators, and realizes efficient and stable standardized production of mixed pulp paper.
