In order to produce molds or cores for foundry purposes from a mixture (M) of molding compound or sand and at least one binder, the mixture is mixed (M) by a mixing device (20) and is fed with the aid of a feeding system (30) to at least one sand storage unit (40) of a core or mold production device (50), wherein the mixture-free region (21) of the mixing device (20), at least at times, and/or the feeding system (30) located between the mixing device (20) and the core or mould production device (50), and/or the sand storage unit (40) downstream of the feeding system (30) and upstream of the core or mould production device (50), is moistened or kept moist by means of a liquid (71). The liquid (71) used for moistening is atomised by at least one ultrasonic atomiser (60) to form a suspended aerosol and is fed to the mixing device (20) and/or the feeding system (30) and/or the sand storage unit (40) via pipes (81, 82, 83). |
