Surface modification of mineral powders is not as simple as adding a small amount of chemical agent to the powder and mixing it uniformly; rather, it requires that the modifier be dispersed as thoroughly as possible across the particle surfaces and that spreading or interfacial interactions be achieved under appropriate temperature, mechanical conditions, and residence time.

When coating equipment processes materials such as calcium carbonate, talc, fumed silica, and oxides, it is first necessary to determine the powder’s particle size, specific surface area, moisture content, and the type of modifier. If agglomerated particles are present inside the modification‑activation machine, even with an adequate dosage of the modifying agent, localized over‑coating and insufficient treatment on certain particle surfaces may still occur.

The honeycomb mill integrates powder dispersion, gas–solid conveying, heating, and dispersing of modifiers into a continuous process, with temperature, linear velocity, and injection method adjustable according to the material’s properties. The modification effect should not be evaluated based on a single criterion. In addition to assessing the “activation degree” index, it is also necessary to measure the oil absorption value, contact angle, particle size distribution, and the actual dispersion performance in downstream plastics, rubbers, or coatings to determine whether the process is appropriately matched.
