Coatings and Dyes Solutions
The coatings and dyes industries impose extremely stringent requirements regarding the whiteness, fineness, dispersibility, and chemical stability of powdered materials. Our equipment is ideally suited for the precision processing of light calcium carbonate, heavy calcium carbonate, talc, and various other high-whiteness functional fillers. These mineral powders serve not only as extender pigments in coatings and dyes—helping to reduce production costs—but also play a pivotal role in enhancing coating opacity, gloss, and weather resistance, as well as improving the color fastness of dyes. By leveraging advanced ultrafine grinding and classification technologies, our equipment transforms natural ores into ultrafine powders characterized by high specific surface area and a narrow particle size distribution. This effectively resolves common pain points associated with traditional fillers—such as poor dispersion within resin matrices, susceptibility to sedimentation, and low gloss levels—thereby empowering coatings and dyes enterprises to successfully transition toward high-end, functional, and eco-friendly production.

Process & Solutions
Addressing the specific requirements of the coatings and dyes industries for powders that are “ultra-fine, highly white, and high-purity,” our equipment executes a complete process encompassing crushing, grinding, classification, powder collection, and packaging—thereby ensuring that the finished powder meets the rigorous standards for high-end applications in terms of its microscopic morphology.

Stage 1:Crushing
Large-sized raw materials first undergo coarse crushing in a jaw crusher, followed by fine crushing in an impact crusher to control the particle size within the range of 5 mm to 15 mm. For materials requiring exceptionally high whiteness, iron removal is performed during this stage to prevent the contamination of the product by metallic impurities, which could compromise its color.
Stage 2:Grinding and Classifying
After crushing, the smaller material fragments are conveyed by an elevator into the raw material bin, and then fed uniformly and quantitatively by a vibrating feeder into the grinding chamber of the mill.
● Ultrafine Powder Processing: To address the demand for high-end coating and dye fillers ranging from 1,250 to 5,000 mesh, we primarily recommend our CLUM series ultrafine vertical mills and HGM series ultrafine micro-powder mills. The CLUM vertical mill integrates crushing, drying, grinding, and classifying functions into a single unit, producing ultrafine powders with superior particle morphology that significantly enhance the leveling properties of coatings. The HGM micro-powder mill, featuring a design utilizing multi-layer grinding rings and suspended rollers—combined with a high-precision classifier—is capable of consistently producing ultrafine powders with a D97 fineness of ≤5μm, entirely free from metal contamination.
●High-Purity Ultrafine Powder Processing: For functional fillers requiring specific crystalline morphologies or exceptionally high purity, we recommend utilizing the CLJM series Air Jet Mills or the CLCM series Vortex Mills. Air jet mills employ high-velocity airflow to achieve autogenous grinding, thereby preventing contamination from grinding media; vortex mills achieve ultrafine pulverization through high-speed shear forces, effectively preserving the material’s crystalline structure and enhancing suspension stability.
Stage 3:Powder Collecting
Following grinding, the material is carried by the airflow into a high-efficiency turbine classifier. By adjusting the rotational speed of the classifying wheel, the desired particle size range can be precisely cut (e.g., D97 ≤ 10 μm or D97 ≤ 5 μm). The qualified fine powder is conveyed by the airflow into the collection system, while coarse particles automatically fall back into the grinding chamber for further processing. This establishes a closed-loop circulation system, ensuring that the finished product exhibits an extremely narrow particle size distribution and is free of coarse impurities.
Stage 4:Modification
Fine powder meeting the specified fineness requirements is carried by the airflow into a pulse dust collector for gas-solid separation. The entire system operates under negative pressure and is equipped with a long-bag, low-pressure pulse dust collector; consequently, dust emission concentrations remain far below national standards, and collection efficiency reaches as high as 99.9%. The collected finished powder is discharged via a discharge valve and proceeds to the next processing stage.
Stage 5:Packaging
After cooling, the finished powder is packaged—either in 25kg bags or one-ton bags—using an automated packaging machine. The entire process involves fully enclosed conveying to ensure zero dust contamination, thereby safeguarding the cleanliness of the finished product during transport and storage.
