Crushing device for chemical industry production

The invention discloses a crushing device for chemical industry production. The crushing device for chemical industry production comprises a crushing machine body. The crushing machine body is divided into a crushing cavity and a smashing cavity in an upper-lower mode. The bottom end of the left side of the crushing cavity is connected with a feeding pipe, a feeding hopper is arranged on the upper side of the feeding pipe, and an iron removing rotary shaft is horizontally arranged in the center in the feeding hopper. Permanent magnet sheets are arranged on the outer wall of the iron removing rotary shaft in a vertically symmetrical mode. A telescopic column is vertically arranged in the center in the crushing cavity, the top end of the telescopic column stretches out of the crushing cavity and is connected with a hydraulic cylinder fixed on the outer wall of the upper side of the crushing machine body, and the bottom end of the telescopic column is connected with a crushing hammer arranged horizontally. The crushing device for chemical industry production can conduct iron removing on materials twice, thereby being good in iron removing effect and sufficient in iron removing; two crushing mechanisms arranged up and down are adopted for sufficiently crushing materials, gears are engaged to conduct crushing, and thus the crushing effect is good, and crushing is sufficient; and besides, effective shock absorption can be achieved, and the service life of the machine body is prolonged.

Different-orientation spherical natural graphite negative electrode material and preparation method thereof

The invention relates to a different-orientation spherical natural graphite negative electrode material and a preparation method thereof. The method comprises the following steps: mixing natural crystalline flake graphite micro powder and dispersion medium; adding deflocculants for regulating the solid content; then, placing materials and bonding agents into a pulp mixing machine to be stirred; carrying out atomization, drying and granulation on the pulp on a spraying drying machine to obtain powdery materials; carrying out heat treatment on the powdery materials in nitrogen gas atmosphere through a revolving furnace; and cooling the obtained powder to obtain the different orientation spherical natural graphite negative electrode material. The graphite negative electrode material consists of a plurality of layered graphite crystalline flakes, and the layered graphite crystalline flakes are glued and have different orientations. The graphite negative electrode material prepared by the method of the invention has the obvious characteristics that the specific capacity of the material is high, the circulation stability is high, the micro spheres formed by the graphite flakes of the graphite with different orientations can effectively inhabit the layer flake peeling caused by deep lithium insertion, the graphite flake adhesion and the carbon coverage can be realized at the same time, the powder agglomeration can be avoided through dynamic sintering, and the invention is favorable for obtaining the spherical natural graphite micro powder with uniform granularity.
