Abstract

Disclosed herein are a process and a plant for recycling used batteries, the plant including: a first comminuting device to comminute used batteries to a first degree of comminution to obtain comminuted battery material; a drying device, arranged downstream of the first comminuting device, to dry the comminuted battery material; a second comminuting device designed to be explosion-proof and arranged downstream of the drying device, to comminute the dried battery material to a second degree of comminution, the second degree of comminution being greater than the first degree of comminution; and a pyrolysis device, arranged downstream of the second comminuting device, to pyrolyse the dried and comminuted battery material.

Dependent claims

A plant for recycling used batteries, comprising:

a first comminuting device to comminute used batteries to a first degree of comminution in a first comminuting space to obtain comminuted battery material;
a drying device, arranged downstream of the first comminuting device, to dry the comminuted battery material;
a second comminuting device arranged downstream of the drying device, to comminute the dried battery material to a second degree of comminution in a second comminuting space, the second degree of comminution being greater than the first degree of comminution;
and
a pyrolysis device, arranged downstream of the second comminuting device, to pyrolyse the dried and comminuted battery material in a pyrolysis space,
wherein at least the second comminuting device is designed to be explosion-proof.
