Abstract

LA INVENCION SE REFIERE A UN PROCESO PARA LA REGENERACION DE LA ARENA USADA EN UNA FUNDICION, CUYA ARENA DE MOLDE DE ORIGEN CONTIENE AGLOMERANTE INORGANICO COMO MATERIAL DEL MOLDE POR EJEMPLO Y ESPECIALMENTE BENTONITA (= "ARENA USADA INORGANICA") Y/O AGLOMERANTE INORGANICO COMO POR EJEMPLO Y ESPECIALMENTE RESINA FENOL Y/O FURANO (="ARENA DE USO ORGANICO"), DONDE LA ARENA USADA A TRATAR SE IMPREGNA EN AGUA Y A CONTINUACION EN UNA SITUACION O CONDICION HUMEDA SE SOMETE A UN PROCESO DE SECADO TURBULENTO EN CAPA.THE INVENTION REFERS TO A PROCESS FOR THE REGENERATION OF THE SAND USED IN A FOUNDRY, WHICH MOLD SAND OF ORIGIN CONTAINS INORGANIC BINDER AS MOLD MATERIAL FOR EXAMPLE AND ESPECIALLY BENTONITE (= "INORGANIC USED SAND") AND / OR AGAN FOR EXAMPLE AND ESPECIALLY PHENOL AND / OR FURAN RESIN (= "SAND FOR ORGANIC USE"), WHERE THE SAND USED TO TREAT IS IMPREGNATED IN WATER AND FOLLOWING IN A SITUATION OR WET CONDITION, IT IS SUBJECT TO A TURBULENT DRYING PROCESS IN LAYER.
