Abstract

The invention discloses a battery negative electrode material mixing device with cyclic grinding equipment. The battery negative electrode material mixing device comprises a mixing chamber; a discharge pipe is arranged at the bottom of the mixing chamber; a stirring mixing device is arranged inside the mixing chamber; the stirring mixing device is composed of a bottom scraper blade, a through hole, a first vertical rod, a second vertical rod, a stirring shaft, a spiral stirring blade and a stirring motor. The battery negative electrode material mixing device is simple in structure, reasonable in design and convenient to use; due to arrangement of a grinding chamber, materials can be ground, a filter plate at the bottom of the grinding chamber can filter out qualified materials obtained after grinding, then, small and large materials are separated out through an inclined plate, large-particle materials can be input into the grinding chamber again through a cyclic feeding device, secondary grinding treatment is performed, small-particle materials are separated out through the inclined plate to be input into the mixing chamber, and the materials and additives are mixed; the stirring mixing device can greatly increase the material mixing speed, the material production time can be shortened, and the production rate can be increased.

Description

technical field [0001] The invention relates to battery production equipment, in particular to a battery negative electrode material mixing device with circulation crushing equipment. Background technique [0002] Lithium battery (Lithium battery) refers to the battery containing lithium in the electrochemical system. Lithium battery can be roughly divided into two types: lithium metal battery and lithium ion battery; the negative electrode material of lithium battery is mainly graphite. When producing lithium battery negative electrode, Graphite needs to be crushed, screened, mixed, etc., and crushing is a relatively important process, which requires uniform particle size and high crushing efficiency; however, the size range of the particles crushed by the existing crushing device is relatively large. In the later screening process, many particles do not meet the production requirements and need to be reprocessed, and the crushing efficiency needs to be improved. Contents...
