Abstract
An apparatus for regenerating foundry sand comprising; a first chamber (13) having a sand input (16) and a sand output (17), and a source (14) of microwave radiation, the first chamber further comprising a waveguide for microwave radiation, and the microwave source (14) supplying the first chamber with microwave energy such that substantially all of the sand passing through the chamber is heated to a temperature of at least 580{C, the apparatus further comprising a second chamber (23) associated with the first chamber(13) and positioned such that sand exiting the first chamber (13) via the sand output enters the second chamber (23), the second chamber (23) serving as a phase conversion chamber.
