Lithium battery natural graphite multistage crushing device

Abstract

The invention discloses a lithium battery natural graphite multistage crushing device. The lithium battery natural graphite multistage crushing device comprises a primary crushing barrel, a rotary shaft, a lower grinding plate and a crushing device body, a plurality of universal wheels are arranged at the lower end of the crushing device body, a feeding port is formed in the upper end of the crushing device body, the primary crushing barrel is arranged at the lower end of the feeding port, and gear rails are arranged on the surfaces of the two sides of the interior of the primary crushing barrel. The primary crushing barrel is arranged, a graphite raw material is directly placed into the primary crushing barrel through the feeding port, in the primary crushing barrel, a second rotary motordrives a driving crushing roller to rotate, the driving crushing roller drives auxiliary crushing rollers to rotate through shaft moving connecting rods at the two ends, meanwhile, the auxiliary crushing rollers move on the inner side surfaces of the gear rails through gears at the two ends so as to drive a secondary crushing barrel to rotate to cooperate with the driving crushing roller to actively crush the graphite back and forth, so that the graphite raw material is crushed into graphite particles which are uniform particles, and the crushing quality is improved.

Description

Technical field [0001] The invention relates to a crushing device, in particular to a natural graphite multi-stage crushing device for lithium batteries. Background technique [0002] Graphite is an allotrope of elemental carbon. The periphery of each carbon atom is connected with three other carbon atoms (multiple hexagons arranged in a honeycomb) covalently bonded to form a covalent molecule. Since each carbon atom emits an electron, those electrons can move freely, so graphite is an electrical conductor. Graphite is one of the softest minerals, and its uses include making pencil leads and lubricants. Carbon is a non-metallic element, located in the IVA group of the second period of the periodic table. [0003] In the production process of lithium batteries, graphite powder is needed. This is made of graphite. When graphite is turned into powder, it needs to be crushed. The existing crushing device has slow crushing efficiency and low crushing quality. Larger, often cannot be ...

Problems solved by technology

[0003] In the production process of lithium batteries, graphite powder is needed, which is made of graphite. When graphite is turned into powder, it needs to be crushed. The existing crushing device has slow crushing efficiency and low crushing quality. Larger, often cannot be crushed into the graphite powder required for production, and cannot meet the production demand
