Abstract (en)
[origin: EP0580084A2] Method for regenerating foundry sand in regenerators in which the dust is discharged pneumatically. During the regeneration process, the density of dust in the discharge air is continuously measured and the measured values are used as signals for the control of the regeneration process.
