Core sand reclamation

Core sand | hot separation and reclamation

In the core package process with binder-free backfill sand, there is a significant challenge in the separation of castings and core sand lumps. The separated lumps are broken and crushed to single grain and hot reclaimed in a 1-stage airlift system and pre-classified in the silo. After that, oversize particles are screened, fine iron is separated and the reclaimed material is cooled to operating temperature. Chillers can be cooled and warmed in particularly demanding climatic conditions.
