Natural graphite crushing device for lithium battery processing

Abstract

The invention discloses a natural graphite crushing device for lithium battery processing. The natural graphite crushing device comprises a supporting mechanism, an extrusion mechanism, a first crushing mechanism and a discharging port, wherein the supporting mechanism comprises a crushing box, supporting legs, a sealing door, a top cover and a feeding port, the front side of the crushing box is rotationally connected with the sealing door, the top cover is arranged at the top of the crushing box, the outer sides of extrusion plates are connected with hydraulic cylinders, the hydraulic cylinders are arranged at the tops of the supporting legs, the first crushing mechanism is arranged below the extrusion mechanism, and a second crushing mechanism is arranged below the first crushing mechanism. According to the natural graphite crushing device for lithium battery processing, the hydraulic cylinders are arranged, the hydraulic cylinders can drive crushing cutters on the extrusion plates to extrude and crush graphite in a circulating and reciprocating mode, meanwhile, a screening net is arranged, the screening net can filter graphite particles crushed for the first time, and the graphite blocks with overlarge sizes remain on the screening net and are extruded by the crushing cutters again, so that the crushing uniformity can be ensured to a certain extent.

Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to a natural graphite crushing device for lithium battery processing. Background technique [0002] Natural graphite, as the name implies, is graphite that is naturally formed in nature. It generally appears in the form of graphite schist, graphite gneiss, graphite-containing schist and metamorphic shale. It is mainly used in pencils, batteries, welding rods, graphite emulsion, graphite Ingredients for bearings and raw materials for battery carbon rods, etc. Graphite powder needs to be used in the processing of lithium batteries, so crushing devices are needed to crush graphite. Most of the existing crushing devices only have one crushing process, which is prone to uneven crushing. On the other hand, Some crushing devices are prone to diffuse graphite debris when crushing graphite, which is likely to pollute the working environment and cause waste of graphite res...
