Abstract
EL INVENTO SE REFIERE A UN PROCEDIMIENTO PARA CALCINAR TORTAS DE FILTRACION EN HORNOS ROTATIVOS TUBULARES DE CALENTAMIENTO DIRECTO. EL PROCEDIMIENTO SE CARADCTERIZA PORQUE UNA PARTE DE LA TORTA DE FILTRACION SE PRESECA, ANTES DE INTRODUCIRLA EN EL HORNO ROTATIVO TUBULAR Y EL RESTO DE LA TORTA DE FILTRACION, SE UNE CON LA PARTE DE LA TORTA DE FILTRACION PRESECADA.
