Device for grinding battery material graphite

Abstract

The invention discloses a battery material graphite grinding device, comprising a crushing device and a storage device; the crushing device is provided with a material inlet, a fastener, a first motor, a transporter, a casing, a second motor, a rotating shaft, and a blade , a screen, a vibrator, a grinding net, a third motor, a bump, a rotating shaft, a connecting rod, a pressure wheel and a conveyor belt; At the bottom right of the material inlet; the conveyor is vertically fixed at the center of the left end of the first motor; the second motor is fixed inside the casing; the rotating shaft is vertically fixed below the second motor central position; the raw material graphite of the present invention enters the crushing device from the feed port; the fastener controls the opening and closing of the feed port; the first motor drives the conveyor to make the raw material in the feed port enter the crushing device; the casing The second motor plays a protective role; the second motor drives the rotating shaft to rotate.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a battery material graphite grinding device. Background technique [0002] Lithium batteries have a high storage energy density, which has reached 460-600Wh / kg, which is about 6-7 times that of lead-acid batteries, so they have the characteristics of high energy; the service life of lithium batteries can reach more than 6 years, making them relatively High service life; the many advantages of lithium batteries make it gradually replace traditional lead-acid batteries, suitable for various fields; there are many kinds of negative electrode materials for lithium batteries, and artificial graphite is often used as the negative electrode material of lithium batteries; graphite Making lithium battery anode materials needs to go through processes such as crushing, screening, and stirring; the above-mentioned process requires a graphite pulverizer. It is difficult for a machine to process graphit...

[0002] Lithium batteries have a high storage energy density, which has reached 460-600Wh / kg, which is about 6-7 times that of lead-acid batteries, so they have the characteristics of high energy; the service life of lithium batteries can reach more than 6 years, making them relatively High service life; the many advantages of lithium batteries make it gradually replace traditional lead-acid batteries, suitable for various fields; there are many kinds of negative electrode materials for lithium batteries, and artificial graphite is often used as the negative electrode material of lithium batteries; graphite Making lithium battery anode materials needs to go through processes such as crushing, screening, and stirring; the above-mentioned process requires a graphite pulverizer. It is difficult for the machine to process graphite into the required particle size, and subsequent processing steps are required to increase the construction cost; if the follow-up processing steps are not added, the quality of the final lithium battery negative electrode material will be low
