As lithium batteries are gradually entering the decommissioning period, the battery crushing technology process in the waste lithium battery recycling and treatment equipment is an important link to achieve resource reuse and environmental protection.

With the continuous progress of technology, the battery crushing process will be more effective, safe and environmentally friendly, contributing to the promotion of the sustainable development of the new energy automobile industry.

The crushing process of waste lithium batteries mainly breaks down the battery shell and internal materials through mechanical force. Battery crushing technology is generally divided into the following steps:

Classification: Before crushing, waste lithium batteries need to be classified due to different battery types.

Crushing: The pre-treated battery enters the crusher, and the battery is crushed using strong mechanical tools. The design of the crusher usually takes into account the structural characteristics of the batteries, and ensures that the batteries can be effectively crushed through the appropriate rotational speed and tool layout.

Separation: The crushed mixture contains a variety of materials such as metals, plastics and electrolyte. Through vibrating screen, air separation, magnetic separation and other sorting techniques, different materials are separated to extract precious metals such as lithium, cobalt and nickel.
