A nanoscale white carbon black pulverizing device

Abstract

This utility model discloses a pulverizing device for nanoscale silica, comprising an inner cylinder, an outer cylinder, and a gas conveying assembly. The inner cylinder has a first pulverizing chamber and a first grinding protrusion, with a first through hole in its side wall. The outer cylinder is fitted over the inner cylinder to form a second pulverizing chamber, with a second grinding protrusion on its inner side. The gas conveying assembly includes a gas conveying pipe coaxially arranged with the outer and inner cylinders, and has an outlet hole. A first rotating assembly drives the inner cylinder to rotate in a first direction, and a second rotating assembly drives the outer cylinder to rotate in the opposite second direction. After being fed into the device by the feeding assembly, the silica particles are graded and pulverized under the shearing force and airflow generated by the counter-rotating inner and outer cylinders, and finally output as nanoscale particles meeting the requirements through the discharge assembly. This device achieves highly efficient nanoscale pulverization of silica particles through a bidirectional pulverizing structure.
