Considerations for Reclaiming Chemically Bonded

The factors that justify sand reclamation are changing, and redefining the planning process. Reclamation and reuse of foundry sands has always made economical and environmental sense, however the recent demands placed on sand by the oil and gas industries has made sand reclamation a process that no foundry can afford to overlook.

Reclaiming Sand, Metal is a Strategy for Reclaiming

The metal is separated from the sand and is thoroughly cleaned before discharging out the opposite end. For foundries that currently ship their spent sand to approved landfill sites, the costs of disposal and new sand purchases can easily justify an in-house Sand Reclamation System.

Life Cycle Assessment in Foundry Sand Reclamation. comparison was made between a sand reclamation train model without any secondary sand reclamation, secondary reclamation using a mechanical process, a thermal process, and a microwave process. An economic, energy balance, and full LCA analysis was conducted for each of these processes.
