Abstract
La presente invención se refiere a procedimiento para el tratamiento de regeneración de arena de fundición usada predominantemente aglutinada con arcilla, para volverse a usar en lugar de arena nueva, en el cual los granos de arena son repetidamente acelerados y desacelerados y son frotados uno con otro mediante un esfuerzo de impacto y un esfuerza de deslizamiento combinados y de esta manera quedan libres de la capa que se adhiere a los granos de arena, la cual capa consiste de aditivos y sustancias de aglutinamiento, con el uso de un dispositivo neumatico que remueve el polvo y lo lleva al exterior, caracterizado en que el contenido de agua de la arena usada del tratamiento de regeneración se fija a lo más al 1 por ciento por peso de agua.The present invention relates to a process for the regeneration treatment of predominantly clay-bonded used foundry sand, to be reused in place of new sand, in which the sand grains are repeatedly accelerated and decelerated and are rubbed against each other by means of a combined impact effort and sliding effort and in this way they are free of the layer that adheres to the grains of sand, which layer consists of additives and binding substances, with the use of a pneumatic device that removes the powder and takes it outside, characterized in that the water content of the sand used in the regeneration treatment is set to no more than 1 percent by weight of water.
