Waste lithium battery recycling method

With the popularization of smartphones, tablets, computers and electric vehicles, people rely more and more on lithium batteries. At the same time, because of the popularity of lithium batteries and social requirements for environmental protection, make the recovery and recycling of used lithium batteries has become an important industry. Lithium battery recycling equipment plays an important role, and is one of the most important in the process of dealing with waste lithium batteries. Through this article, we will introduce the technical program of lithium battery recycling processing equipment, including composition, working principle and equipment advantages.

1 Equipment composition

Lithium battery recycling equipment is composed of shredder, low temperature drying oven, linear vibrating screen, and other multi-component sorting equipment.

(1) Shredder: the discharged lithium batteries are sent into the shredder through the conveyor , so that the batteries can be divided into small pieces of 3-4 centimeters, so as to facilitate the processing of subsequent tools.

(2) Drying equipment: the shredded material is heated and dried by means of natural gas heating. Heat the outside of the furnace body, and use the heating conduction to make the temperature into the inside of the furnace body, so as to achieve the purpose of drying and evaporating the electrolyte and water.

(3) Multi-component sorting equipment: the plastic diaphragm is pre-separated by a multi-component separator in advance according to the material characteristics, so as to reduce the operating pressure of the back-end device. By means of magnetic separation equipment, linear sieve, specific gravity sorting, etc.,  the various metals will be separated out in the waste battery.

2 Working principle.

Lithium battery recycling equipment works by first crushing and drying the discharged lithium batteries, crushing the dried materials again, and these battery fragments are sent to be sent to the multi-component sorting equipment, for example, linear sieve, when the crushed material passes through the linear sieve, it will be separated by the method of vibration sieving to separate out the different materials; magnetic sorting equipment, according to the characteristics of the materials, the magnetic separator can separate out the iron and nickel bands with magnetic properties from lithium batteries, while the other materials will be sent to the next process; the specific gravity sorting equipment is based on the separation of the heavy same as the copper and aluminum.

3 Advantages of the equipment: the advantages of lithium battery recycling equipment are as follows

(1) High degree of automation: the whole process of lithium battery recycling equipment is automated, reducing manual operation and improving production efficiency.

(2) Good separation effect: lithium battery recycling equipment through the multi-component sorting device so that various metals in the lithium battery can be effectively separated, improve the sorting effect.

(3) Wide range of applications: lithium battery recycling equipment can be used for cylindrical batteries, hard shell batteries and soft pack batteries.

(4) High environmental protection: lithium battery recycling machine is equipped with multi-group environmental protection dust removal system to reduce environmental pollution.

Gongyi Xingmao—Lithium battery recycling equipment has advanced technology, which improves the separation effect of lithium batteries and is suitable for various lithium battery recycling enterprises .
