Abstract
A reclamation system is used for mercury-zinc and mercury-cadmium battery disassembly. The mercury-zinc/mercury-cadmium reclamation system has a cooling station, a cracking station, a disassembly station and a shredder station. The cooling station freezes the batteries to facilitate cracking of the housing by the cracking station. The cracked batteries are then disassembled and the battery cells are shredded. The shredded cells are placed in the retort oven, for recovery of mercury. In an alternative embodiment, the reclamation system is used for silver-zinc battery disassembly. The silver-zinc reclamation system has a staging and draining station, cracking station, and disassembly station. At the staging and draining station, wet batteries are separated out and drained. The batteries are then cracked, disassembled and washed. The washed cells are placed in the retort oven, for recovery of mercury.
