Abstract

Un método perfeccionado de quemar harinas crudas de cemento, que comprende las operaciones de (a) alimentar una parte de materias primas de cemento a una primera unidad precalentadora de suspensión que consiste en una pluralidad de etapas de intercambio de calor conectadas en serie para precalentar las materias primas mientras se alimenta la parte restante de los materiales de cemento a una segunda unidad precalentadora de suspensión que consiste en una pluralidad de etapas de intercambio de calor conectadas en serie para precalentar las materias primas, (b) dirigir la totalidad de las materias primas descargadas desde la segunda etapa de intercambio de calor más inferior en dicha segunda unidad precalentadora a un calcinador.
