Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA OBTENCION DE MASAS ESENCIALMENTE SECAS MEDIANTE ELIMINACION DE AGUA MECANICA A PARTIR DE CAUCHO HUMEDECIDO CON AGUA, ELABORADO MEDIANTE POLIMERIZACION DE EMULSION Y PRECIPITACION PARA FORMAR UN CAMPACTADO CON AL MENOS UN 50 % DE CONTENIDO EN CAUCHO. EL CAUCHO CON ELIMINACION PREVIA DE AGUA SE GUIA AL TRAMO DOSIFICADOR DE UN EXTRUSIONADOR DE TORNILLO SINFIN DE DOS EJES CON ROTACION EN CONTRASENTIDO, DONDE SE HAN PREVISTO DOS ZONAS DE ESTANCADO AL MENOS EN LA DIRECCION DE TRANSPORTE, UNA DESPUES DE OTRA, Y DOS ABERTURAS DE ELIMINACION DE AGUA PERTENECIENTES, QUE ESTAN DOTADAS EVENTUALMENTE CON UN TORNILLO SINFIN DE RETENCION, ASI COMO AL MENOS UNA ZONA DE AMASADO, UNA ZONA DE DESGASIFICACION Y FINALMENTE UNA ZONA DE EXTRACCION, QUE ESTA CERRADA EVENTUALMENTE POR MEDIO DE UN LISTON DE TOBERAS Y QUE EXTRAE EL AGUA SEPARADA A PARTIR DE LAS ABERTURAS DE ELIMINACION DE AGUA EN FORMA LIQUIDA.
