| Le procédé permet la récupération du sable de fonderie usé afin qu'il puisse être réutilisé, par l'élimination par combustion des substances charbonneuses organiques qui imprègnent le sable usé. Après l'avoir broyé jusqu'à une grosseur du grain homogène, on place le sable usé dans un récipient cylindrique (2) qui est incliné par rapport à la verticale et que l'on fait tourner lentement (de 4 à 6 tours/min). Puis, on introduit par soufflage un flux d'oxygène dans la base du récipient à l'aide d'un distributeur (5) qui le distribue de manière uniforme dans la masse de sable usé (20). Ensuite, on provoque une combustion localisée à la surface de ladite masse, dans la partie supérieure du récipient, au moyen d'un brûleur (31). Enfin, on éteint le brûleur tout en maintenant le flux d'oxygène, et la combustion continue et s'alimente elle-même grâce à l'effet de la descente progressive du front des flammes (30) vers le fond du récipient jusqu'à ce que les substances charbonneuses et organiques contenues dans le sable aient été entièrement détruites. | ||||||

An apparatus for heat treating contaminated particulate material and more particularly, an apparatus for reclaiming foundry sand. The apparatus includes a heated, inclined rotary drum (3) and an auger (2) projects into the upstream end of the drum (3) and serves to feed material to the drum (3). The auger (2) includes a spiral flight (7) carried by a hollow shaft (8) and a blower (18) is connected to the outer end of the hollow shaft (8) so that air is supplied through the shaft (8) into the drum (3). A seal is provided between the non-rotating auger housing (9) and the drum (3), and the seal includes an annular bearing plate mounted on the end of the drum (3) while a sealing ring is connected to the auger housing (9) and is biased against the plate to provide a seal. The excess air in the heated drum (3) burns off the organic contaminates from the particulate material and calcines the mineral contaminates. The treated particulate material is transferred from the downstream end of the drum (3) to a second cooling drum (5) and air is passed through the second drum (5) countercurrently to movement of the particulate material to cool the material. |

| Appareil (14) comportant des mécanismes d'échange thermique pour le traitement de matériaux solides, granulaires et agglomérés, et en particulier pour le traitement de sable de fonderie à liaison chimique, épuisé, c'est-à-dire utilisé. L'appareil (14) comporte un premier mécanisme de chambre pivotant (16) où le sable de fonderie utilisé est préchauffé pendant qu'il se déplace dans une première direction à travers celui-ci, d'une extrémité à l'autre. Du premier mécanisme de chambre (16), le sable de fonderie utilisé préchauffé est avantageusement amené à un mécanisme de récupération thermique (12) afin d'en retirer thermiquement les substances organiques. Le sable de fonderie utilisé est ensuite amené à un deuxième mécanisme de chambre (44) où le sable de fonderie utilisé subit une post-récupération par laquelle toute matière organique pouvant rester dans le sable de fonderie en est retirée thermiquement. Du deuxième mécanisme de chambre (44), le sable de fonderie est forcé de passer dans un troisième mécanisme de chambre (52) situé en relation d'échange de chaleur par rapport au premier mécanisme de chambre (16). Au fur et à mesure que le sable de fonderie utilisé traverse le troisième mécanisme de chambre (52) dans une seconde direction, il y a échange de chaleur entre le sable de fonderie traversant le troisième mécanisme de chambre (52) et le sable de fonderie traversant le premier mécanisme de chambre (16) si bien que le premier perd de la chaleur c'est-à-dire se refroidit et que le dernier absorbe de la chaleur, c'est-à-dire est préchauffé. | ||||||

The grinding device further includes a fluidizing device for fluidizing the granular bodies in a floating state by sending air from the bottom surface portion of the case, to form a fluidized bed in which at least a part of the grinding surface is soaked. | ||||||
| 135 | METHOD AND MACHINE FOR DRYING MATERIALS | US14407344 | 2013-05-16 | US20150121717A1 | 2015-05-07 | Falk Denke |
| A method and a drying machine for drying materials, for example foundry sands, laundry, chemical pulps and/or bulk materials. The materials to be dried are loaded into a drying container, in which liquid is vaporized. The steam produced is passed into a condensation chamber and condensed there in thermal contact with the material from the drying container. In this way, the heat of condensation can be recovered for a renewed vaporizing process. The drying machine may be used in particular in a regeneration plant for inorganically bound foundry sands. | ||||||
