Three-Roller Vortex Talc Surface Activation Modification Mill

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

Three serial triangular staggered rotor units rotate at high speed to generate cross-direction turbulent vortex. Talc agglomerates are fully dispersed under repeated shear and collision between multi-stage chambers. Friction between talc flakes and rotors generates stable heat to melt coating agents, enabling full contact between modifier and talc surface active sites for uniform surface activation treatment.

The whole system runs under full negative pressure to prevent dust leakage. Modified loose talc powder is conveyed to cyclone & bag dust collectors. It can directly connect upstream grinding and drying equipment without intermediate storage silos to form a one-stop closed talc deep processing production line.
