In the production of high-end coated paper, calcium carbonate serves as a critical filler, and the uniformity of its particle size directly affects the paper’s smoothness and brightness. Conventional grinding processes often struggle to achieve both objectives simultaneously. “ Extremely fine ” and “ Uniform ” , resulting in noticeable streaks or a grainy texture in the coating.
The introduction of the cell mill offers a new pathway for upgrading papermaking fillers. Thanks to its unique vertical shear‑type design, the trajectory of calcium carbonate particles within the chamber is precisely controlled, ensuring that each particle receives a uniform level of energy. This high degree of consistency means that the resulting ultrafine calcium powder can meet coating‑grade specifications without relying on complex screening steps. Moreover, the cell mill demonstrates exceptional stability in wet‑processing conditions, efficiently handling high‑concentration slurries and significantly boosting throughput per unit time. For plants requiring large‑scale production of high‑performance fillers, this equipment not only streamlines the process but also enhances product value, directly strengthening the company’s market bargaining power and driving an industrial upgrade from quantitative expansion to qualitative improvement.
