Abstract

This application provides a pulverizing and mixing device for battery materials, particularly relating to the technical field of pulverizing devices for battery material production. The device includes a pulverizing tank, a first housing, and a mixing assembly. The pulverizing tank has a pulverizing chamber and an inlet and an air inlet communicating with the pulverizing chamber. The inlet is used to introduce material into the pulverizing chamber, and the air inlet is used to introduce airflow into the pulverizing chamber, so that the airflow accelerates the material particles within the pulverizing chamber and causes the particles to collide and pulverize into pulverized material. The first housing has a mixing chamber and an outlet communicating with the mixing chamber. The mixing chamber is connected to the pulverizing chamber. The mixing assembly is mounted on the first housing and is adapted to uniformly mix the pulverized material entering the mixing chamber. This application utilizes airflow to pulverize materials and then mixes them, allowing the uniformly mixed material to be directly sintered, significantly simplifying the battery material production process, reducing production costs, and improving production efficiency.
