Mobile crushing device for graphite for manufacturing negative electrode materials for lithium batteries

Abstract

The invention provides a mobile crushing device for graphite for manufacturing negative electrode materials for lithium batteries. The mobile crushing device comprises a primary feeding and crushing device and a secondary crushing and receiving device; the primary feeding and crushing device comprises a feeding box, a first motor, crushing rotating wheels and a carrying box, wherein the carrying box is welded on four wheel supports, the feeding box is welded to the left side of the upper part of the carrying box, the crushing rotating wheels are fixedly arranged on rotating shafts and are arranged in the feeding box, and the first motor is fixedly arranged on the left side of the carrying box; and the secondary crushing and receiving device comprises a secondary crushing box, a loading box and a receiving box, wherein the secondary crushing box is welded on the left side surface of a right carrying plate and the right side surface of a left carrying plate, the loading box is fixedly arranged on the right carrying plate, and the receiving box is arranged on the bottom surface of the carrying box and right below a discharging pipe. The mobile crushing device for the graphite for manufacturing negative electrode materials for lithium batteries has the advantages that the graphite is crushed twice to reach the standard without additional subsequent procedures, time and labor are saved, and the construction cost is saved.

Description

technical field [0001] The invention relates to a lithium battery negative electrode material processing device, in particular to a mobile lithium battery negative electrode material graphite crushing device. Background technique [0002] The existing lithium battery negative electrode materials are divided into five types: the first is carbon negative electrode materials, and the negative electrode materials that have been actually used in lithium ion batteries are basically carbon materials, such as artificial graphite, natural graphite, and mesocarbon microspheres. , petroleum coke, carbon fiber, pyrolytic resin carbon, etc.; the second is tin-based negative electrode materials, which can be divided into tin oxides and tin-based composite oxides; there are currently no commercial products; the third It is a lithium-containing transition metal nitride anode material, and there is no commercial product at present; the fourth is an alloy-based anode material, which includes ...
