ELE Sand Mill Empowers Ultra-Fine Grinding of Optical Brighteners

In the processing of optical functional materials, the color rendering efficiency and dispersion stability of optical brighteners directly depend on their microscopic particle size. Traditional dry crushing easily causes particle heating and secondary agglomeration, so many fine chemical enterprises are seeking high-efficiency wet grinding solutions. As a well-known domestic sand mill manufacturer, ELE has developed high-performance grinding equipment tailored to the characteristics of this material. By adopting advanced ELE sand mills, manufacturers can realize deep refinement of optical brighteners within an extremely short circulation cycle.

According to laser particle size analysis reports from R&D laboratories, the volume average diameter of the original optical brightener sample reaches 37.15 μm, and its D90 index is as high as 80.08 μm. Such coarse particle size not only slows down the dissolution rate of the product but also tends to cause color spots and uneven coating on finished products. After high-energy grinding by the ELE sand mill, test data shows that the volume average diameter drops sharply to 0.627 μm, and the core indicator D90 is reduced to 1.445 μm, demonstrating remarkable ultra-fine deagglomeration capacity. This qualitative leap brought by ELE sand mills thoroughly solves sedimentation and dispersion problems of optical brighteners in downstream applications.

Such remarkable refining effect benefits from the excellent energy density distribution inside the ELE sand mill. The equipment adopts special high-wear-resistant dispersion discs and customized grinding chambers, which generate strong shear force and collision force at high speed. As an experienced sand mill manufacturer, ELE has specially optimized the temperature control system, effectively preventing molecular structure damage of optical brighteners caused by local overheating during strong shearing, and perfectly preserving the optical activity of materials.

Besides superior grinding fineness, equipment stability and ease of use are also key concerns for enterprises. During R&D, ELE fully considered the requirements of automatic cleaning and fast material change. ELE sand mills feature excellent sealing performance, which not only avoids cross-contamination of materials but also greatly reduces labor costs for daily maintenance, providing solid support for high and stable production in factories.

Selecting high-quality grinding equipment is the key to increasing the added value of chemical products. As a professional sand mill manufacturer serving high-tech fields, ELE continues to take technological innovation as the driving force. In the future, ELE will keep optimizing and upgrading the ELE sand mill product line to provide more accurate and efficient integrated wet ultra-fine grinding solutions for more customers in advanced materials.
