Three-Roller Vortex Surface Modification Mill

Flaky dry kaolin powder is quantitatively fed into the first mixing chamber via sealed screw feeder; solid modifiers (stearic acid, aluminate, titanate) are metered synchronously by dosing pump.

Three serial triangular staggered rotor units rotate at high speed to generate cross-direction turbulent vortex. Kaolin agglomerates are fully dispersed under repeated shear and collision between multi-stage chambers. Friction between kaolin flakes and rotors generates stable heat to melt coating agents, enabling full contact between modifier and kaolin surface hydroxyl groups for even surface coating.

Whole system runs under full negative pressure to prevent dust leakage. Modified loose kaolin powder is conveyed to cyclone & bag collectors. It can directly connect upstream grinding/drying equipment without intermediate silos to form one-stop closed production line.
