METHOD AND DEVICE FOR TEMPERATURE RISING AND DRYING OF CEMENT INCLUDING MOLDING

摘要

PROBLEM TO BE SOLVED: To enhance intensity of a molding including a large amount of moisture content immediately after molding, for example, including by exceeding 11%, up to intensity which is capable of handling (3 N/mmor more by collapse intensity) at an early stage (within 1 day).SOLUTION: Provided is the method for temperature rising and drying of a cement including molding which is obtained by molding a fine powdery ore by a molding machine, using cement as a coupling agent, in which (i) a band dryer is arranged, immediately rear the molding machine, and the cement including molding immediately after molding is subjected to temperature rising and drying, and (ii) difference between moisture contents on upper and lower layers of the cement including molding is reduced to 3 mass% or less at an outlet side of the band dryer.
