APPARATUS FOR PRODUCING ZINC FLAKE

摘要

The present invention relates to an apparatus for producing zinc flake, in which a holding tank for supplying spherical zinc powder mixture materials and a ball mill are interconnected via an inlet line and an outlet line to flake the spherical zinc powder while circulating the mixture materials introduced in the holding tank. Particularly, as the present invention employs a complex ball mill having an inner cylinder constituted by a plurality of disks stacked into layers, zinc flake with superior quality is obtained to minimize porosity, protective effects against elements which might cause a corrosion can be increased, and the specific surface area of the zinc flake is increased to improve performance of corrosion-protective pigment. Further, the present invention adopts a continuous preparation process to shorten preparation time, thus improving productivity and yield rate, and allowing the commercial utilization thereof.
