AI Technical Summary

Technical Problem

Existing mixing and grinding equipment has difficulty effectively breaking down hard agglomerates in the preparation of barium titanate powder. Furthermore, prolonged compression of materials in a fixed area leads to localized accumulation, affecting the uniformity of powder dispersion and the dielectric properties of the sintered ceramic.

Method used

The grinding head is driven by a point-pecking drive mechanism to perform intermittent downward pressure, combined with airflow assistance, to achieve instantaneous shearing and efficient mixing, avoid local accumulation and temperature rise, and ensure uniform distribution of powder.

Benefits of technology

It improves the crushing efficiency of barium titanate powder, reduces the risk of agglomeration and clumping, and enhances the dispersion uniformity of the powder and the dielectric properties of the sintered ceramic.

Abstract

This invention discloses a mixing and grinding device for preparing barium titanate, comprising: a lifting frame fixed to the rear end of a base and equipped with a lifting drive mechanism; a lifting platform slidably mounted on a slide rail on the front of the lifting frame and driven by the lifting drive mechanism; a grinding cylinder fixed to the front end of the base; and a grinding head mounted on the lifting platform and slid into the grinding cylinder by the downward movement of the lifting platform. The grinding head is driven by a peck-type drive mechanism, enabling it to perform intermittent downward pressing actions while rotating continuously. In this invention, the grinding head employs intermittent downward pressing grinding, applying high pressure to the material in a short time, creating an effect similar to "impact crushing," generating instantaneous shear force and compressive stress on hard agglomerates or large particles, accelerating their crushing, thereby improving the uniformity of the ground particles.
