Abstract
Un procedimiento y una instalación para el tratamiento térmico de material de grano fino, en especial para la producción de cemento, siendo precalentado el material en un calentador previo, siguiendo siendo caldeado en una zona de calcinación previa bajo adición de combustible adicional, terminando de ser calcinado en un horno tubular giratorio, y siendo enfriado en un refrigerador para lo cual el material precalentado es introducido en una corriente de aire de refrigeración procedente del refrigerador, y la mezcla de sólido -gas producida con ello se introduce de lado en una conducción de gas por la que circulan desde abajo hacia arriba los gases de escape del horno, y que comunica el horno tubular giratorio con el calentador previo, caracterizándose el procedimiento por el hecho de que la corriente de aire de refrigeración derivada del refrigerador se divide en varias corrientes parciales, que se introducen por puntos periféricos distintos en la conducción de gas por la que circulan los gases de escape del horno y que forma la zona de calcinación previa, y porque se introducen cantidades parciales correspondientes del material precalentado en las corrientes parciales de aire de refrigeración inmediatamente antes de que éstas penetren en la conducción de gases de escape del horno
