The effectiveness of mineral filler modification and deagglomeration often hinges on equipment selection. A wide variety of surface‑modifying and deagglomeration machines are available on the market; when choosing, first assess the material to be processed: mineral powders such as heavy calcium carbonate, talc, and wollastonite differ significantly in particle size, moisture content, and surface properties, requiring different types of equipment. Next, consider process integration: after modification, deagglomeration is typically required. Whether the equipment can handle continuous feeding and discharging, and whether a single unit can simultaneously perform both modification and deagglomeration, directly impacts production line configuration and floor space requirements.

The honeycomb mill integrates surface modification and deagglomeration functions into a single unit. In a high‑velocity air stream, the material is deagglomerated and dispersed, while the modifier is uniformly coated and simultaneously broken up, eliminating intermediate handling and minimizing secondary agglomeration of the powder. When selecting equipment, consider its suitability for particle size, moisture content, and modifier dosage, and carefully evaluate energy consumption and maintenance costs. By factoring in the raw material’s moisture and particle‑size requirements, you can develop an optimal modification‑and‑deagglomeration solution tailored to multifunctional mineral filler processing, ensuring long‑term, stable operation of the production line.
