Waste Battery Treatment Plant in Bad Oeynhausen
At the DELA business location in Bad Oeynhausen, Germany, treatment of zinc-carbon and alkali-manganese batteries proceeds mechanically by means of crushing, screening and sorting processes. The waste battery plant runs in a dual-shift operation and is currently equipped to process up to 2.5 tons of batteries per hour. The batteries are optionally supplied in barrels, Big Bags, ASP-type special waste containers or other container types.
In a first step, the batteries are crushed and hence mechanically broken up. Subsequent to fragmentation the heterogeneous material obtained is separated on a vibrating screen to yield a coarse and fine fraction. Ferrous (Fe) components are recovered in the coarse fraction. The ferrous metals recovered in the treatment process are marketable and can re-enter the cycle of raw materials.
The separated fine fraction consists of a metal-carbon mixture. This “black mass” is directly filled into container and subsequently brought into a waelz process for material recovery. The main product obtained in this process is a zinc concentrate, also referred to as waelz oxide, which can be reused as a secondary raw material in metallurgic zinc production.
