A PROCESS, APPARATUS, AND SYSTEM FOR RECOVERING MATERIALS FROM BATTERIES

The invention pertains to an apparatus for carrying out size reduction of battery materials under immersion conditions, comprising: a housing configured to hold an immersion liquid; a first feed chute defining an opening therein for receiving battery materials of a first type into the housing; a first submergible comminuting device disposed within the housing to receive the battery materials of the first type from the first feed chute, wherein said first submergible comminuting device is configured to cause a size reduction of the battery materials of the first type to form a first reduced-size battery material; and a second submergible comminuting device disposed within the housing to receive the first reduced-size battery material from the first submergible comminuting device, wherein the second submergible comminuting device is configured to cause a further size reduction in the first reduced-size battery material to form a second reduced-size battery material.
