Embodiment 1
[0042] A wet sorting process for waste lithium batteries, comprising the following steps:
[0043] (1) Perform a stage of wet ball milling under the condition that the ball milling concentration is 60% and the steel ball filling rate is 40% for 1 ton of waste and old ternary square shell lithium battery sorting raw materials to obtain a ball milling product;
[0044] (2) Put the ball mill product into vibrating sieves with mesh sizes of 2mm and 0.15mm respectively for sieving to obtain coarse-grained grades (coarse-grained grade products are returned to the first stage of ball mill feeding), medium-grained grades and fine-grained grades Grade three screened materials;
[0045] (3) The sieved material of the medium particle size is added with water to adjust the concentration to 50%, and the passing condition is that the steel ball filling rate is 45%, and the sieve size is the second stage wet ball milling-sieving of 0.15mm, and the obtained 0.15 Add appropriate amount of wat...
Embodiment 2
[0051] A waste lithium battery wet separation process, comprising the following steps:
[0052] (1) 1 ton of waste lithium cobaltate soft-pack battery sorting raw materials is subjected to a stage of wet ball milling under the conditions that the ball milling concentration is 55% and the steel ball filling rate is 35%, to obtain a ball milling product;
[0053] (2) Put the ball mill product into vibrating sieves with mesh sizes of 2mm and 0.15mm respectively for sieving to obtain coarse-grained grades (coarse-grained grade products are returned to the first stage of ball mill feeding), medium-grained grades and fine-grained grades Grade three screened materials;
[0054] (3) Add appropriate amount of water to the medium-sized product to adjust the concentration to 52%, and pass the second-stage wet ball milling-sieving with a steel ball filling rate of 40% and a sieve size of 0.15mm to obtain a 0.15-2mm The material is added with an appropriate amount of water to adjust the c...
