Waste roasting sagger crushing and grinding equipment for lithium battery positive pole material

Abstract

The invention discloses a waste roasting sagger crushing and grinding equipment for a lithium battery positive pole material. The equipment comprises a base and a workbench, the front side of the workbench is fixedly connected with a fixing plate, sliding grooves are arranged in the surface of the fixing plate, fixing rods are fixedly connected to the front surface of the base, a first magnet is fixedly connected to the bottom of the workbench, and a second magnet is fixedly connected to the top of the base, a first spring is fixedly connected to the top of the base, and the top of the first spring is fixedly connected with the bottom of the workbench. According to the equipment, the fixing plate, the sliding grooves, the fixing rods, the first magnet, the second magnet and the first spring are arranged to play a role in buffering and damping when the sagger are carried out crushing and grinding work, and a certain protective effect to the equipment is achieved, the service life is prolonged, and a crushing box, afirst motor, a L-shaped rod and a first smashing rod, a hole plate, a second motor, a rotating shaft and a second smashing rod are arranged to play a crushing effect to the sagger.

Description

technical field [0001] The invention relates to the technical field of lightweight saggers, in particular to crushing and grinding equipment for waste roasting saggers used for positive electrode materials of lithium batteries. Background technique [0002] At present, lithium battery cathode materials are calcined at high temperature by using saggers to carry materials. Generally, saggers are used to carry lithium carbonate and metal oxides (manganese, cobalt, nickel, etc.) for high-temperature reaction. Li2O reacts with acidic oxide silica and amphoteric oxide aluminum oxide in the surface layer of the sagger to produce a glassy substance, the main components of which are (LiAlO2, Li2OSiO2, Li4SiO4, LiAlSiO4, (LiCoO2)RR, Li24Mg0. 8 and SiO4, etc.), the average index of consumption of saggers at home and abroad is 200-300 kg per ton of positive electrode materials. Only in 2011, the production of positive electrode materials for lithium batteries in China consumed more than...
