Abstract

The invention provides a two-stage crushing device for graphite for manufacturing negative electrode materials for lithium ion batteries. The two-stage crushing device comprises a first-stage crushing device body, a second-stage crushing device body and a dust removal device; the first-stage crushing device body comprises a feeding cylinder, a screen plate and a first-stage crushing box, wherein the first-stage crushing box is welded on the left side surface and the right side surface of two carrying plates, the screen plate is welded on the inner parts of the two sides of the first-stage crushing box, and the feeding cylinder is fixedly arranged on the left carrying plate; the second-stage crushing device body comprises a second-stage crushing box and a second motor, wherein the second-stage crushing box is welded on two second-stage crushing support frames, and the second motor is fixedly arranged on a motor carrying plate; and the dust removal device comprises a dust collection box and a dust suction machine, wherein the dust suction machine is fixedly arranged on the second-stage crushing box. The two-stage crushing device for the graphite for manufacturing negative electrode materials for lithium ion batteries has the advantages that the size of graphite particles can be uniform through a two-stage crushing mode, the crushing speed can be increased, dust can be removed while crushing is conducted, and the environment can be protected.

Description

technical field [0001] The invention relates to a lithium ion battery negative electrode material processing device, in particular to a lithium ion battery negative electrode material secondary crushing device. 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 categories: 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 ...
