Abstract

The invention relates to a system for recovering foundry sand comprising: a rotary drum open at its upper base for depositing the sand to be recovered therein, a cover which can adopt an open position for allowing passage through the upper base of the rotary drum, and a closed position for closing passage through said upper base, and means for generating electromagnetic radiation installed on the cover, such that when the cover is arranged closing the upper base of the rotary drum, the electromagnetic radiation generated is directed towards the inside of the rotary drum. This technique for recovering foundry sand based on the use of microwave energy successfully cleans the sand at great speed, preventing CO2 emissions, and with low energy consumption.
