On July 16, 2025, Liancheng Jiahui Technology Co., Ltd. obtained a patent for "a preparation device for white carbon black" (announcement number CN223096781U). This device is driven by a single power source through a linkage mechanism design: the stirring rod is responsible for material agitation, and the rotating plate achieves uniform and quantitative discharge, reducing device costs by 20% and maintenance workload by 30% compared to traditional multi power source systems.
The R&D director of Jiahui Technology stated that this technology has been applied to a production line with an annual output of 5000 tons of white carbon black, and the product particle size uniformity (D90 ≤ 15 μ m) has reached the international advanced level. The company plans to complete the nationwide industrial equipment transformation by 2026, with the goal of reducing the investment cost of small and medium-sized production lines to 60% of the industry average level.
