The honeycomb grinding and modification coating process is centered on the core principle of “first depolymerization and drying, followed by simultaneous surface coating.” Relying on the unique turbulent honeycomb structure inside the equipment and the synergistic effect of thermomechanical forces, this process achieves efficient depolymerization, deep drying, and precise coating of non-mineral powders. Within just 3 seconds, it can form a single-layer nano-coating film with a thickness of 20–40 nm, boasting a coating efficiency of 99.2% and an activation rate of 99.8%. This process is particularly well-suited for modifying wet-milled filter cakes and agglomerated powders, endowing non-mineral materials such as calcium carbonate, kaolin, talc, and quartz powder with functions including hydrophobicity, oleophilicity, and anti-agglomeration properties. It thus meets the stringent surface-performance requirements of powders in fields such as coatings, new energy, and high-end rubber and plastics.

The honeycomb grinding and modified coating process employs a wind-swept thermomechanical synergy system, through which... An integrated process—“precise feeding → hot-air drying → honeycomb disaggregation → atomization coating → grading and discharge → collection and capture”—enables the transformation of powders from agglomerates to individual particles and from hydrophilic to functionalized. The entire process is conducted under negative pressure in a sealed system, with no dust leakage, and the utilization rate of the modifying agent exceeds 95%.

The core of the equipment is a vertical multi-stage rotor. + The stator groove structure enables the rotor’s linear velocity to reach 110–160 m/s, generating a turbulent “honeycomb” vortex within the grinding chamber. This vortex, driven by shear forces, friction, and centrifugal force, breaks up agglomerated powders back to their original particle size. Simultaneously, hot air performs synchronous drying; the modifier, atomized through four nozzles, thoroughly wraps around individual particles in a fluidized state, forming a dense nano-coating film. The synergistic combination of chemical bonding and physical adsorption ensures the coating’s exceptional adhesion and durability.

After coating, the talc powder exhibits enhanced barrier properties in plastic films. 30% increase in wear resistance; needle-like wollastonite used in rubber to achieve lightweighting as well as enhanced toughness and strength. ； The metal-free process ensures that the iron content in the quartz powder is below— 5 ppm, used as a filler for lithium-ion battery separators to enhance high-temperature resistance and insulation properties, thereby ensuring battery safety; high-purity mica powder used in electronic coatings for stable insulation performance.
