Description

Technical Field

[0001] The utility model relates to a pulverizing device, in particular to a classified ultra-fine pulverizing device. Background Art

[0002] Graphite powder is soft, black-gray, greasy, and can contaminate paper. Under oxygen-free conditions, its melting point is above 3000°C, making it one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature. It is insoluble in water, dilute acid, dilute alkali, and organic solvents. The material has high-temperature resistant conductivity and can be used as a refractory material, conductive material, and wear-resistant lubricating material. Graphite has broad market prospects as an auxiliary raw material for the production of new high-efficiency energy devices such as fuel cells, lithium-ion batteries, and supercapacitors. At the end of the last century, natural graphite was first used in Japan as a negative electrode material for lithium-ion batteries to replace expensive artificial graphite. At the beginning of this century, my country also successfully applied natural flake graphite raw materials to develop negative electrode materials suitable for lithium-ion battery production, that is, modified products of spherical graphite. The lithium-ion battery industry chain has entered a new era. Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium insertion capacity, low and flat charge and discharge potential, long cycle life, green and environmental protection, etc. As an important part of negative electrode materials for lithium-ion batteries, it is a replacement product for negative electrode materials used in lithium-ion battery production at home and abroad. In the spheroidization process of graphite powder, it is generally crushed and ground by a grinding device to finally form an ellipsoidal or spherical shape. The existing graphite powder grinding device still has the following defects: after the graphite powder is loaded into the grinding container, the graphite powder is crushed and ground by the grinding roller that rotates continuously in the grinding container. At this time, the height position of the grinding rod is fixed, and the graphite powder located on the upper or lower layer of the grinding rod is not easy to be ground, and the sphericity rate of the processed graphite powder is low; and the graphite powder sticking to the surface of the grinding rod is not easy to be collected and ground. Since the graphite raw material cannot be collected in a centralized manner after the crushing process is completed, the work efficiency is greatly reduced. Therefore, the purpose of this utility model is to provide a graded ultrafine grinding device. Utility Model Content
