Discharge in which the coal supplied onto the distribution plate is fluidized and conveyed by low-velocity hot air introduced from below the distribution plate arranged horizontally, and the hot air is discharged to the upper part. A fluidized drying chamber that communicates with pipes and high-velocity hot air introduced from below a horizontally disposed dispersion plate allow the dispersion plate to further fluidly convey the coal fluidized from the fluidized drying chamber toward the discharge path side. A discharge system that blows up fine and fine granular coal to classify it into fine and coarse coal and has an adjustment valve at the top that adjusts the amount of hot air containing the blown up fine and fine coal. A wind-powered classification room in which pipes are connected, a partition wall that partitions the fluidized drying room and the wind-powered classification room with the coal passage remaining, and hot air flowing through the discharge pipe provided above the fluidized-air drying room and the wind-powered classification room. A dust collector is installed to collect the fine and fine coal accompanying the hot air, and a coarse coal cutter is installed in the discharge path to discharge the coarse coal flowed on the dispersion plate of the wind classification chamber. A coal drying/classifying apparatus comprising: a cutter for adjusting the output amount; and a hot air temperature regulator for adjusting the temperature of the hot air supplied from the bottoms of the fluidized drying chamber and the air classification chamber. 2. The coal drying/classifying apparatus according to claim 1, wherein a partition wall separating the fluidized drying chamber and the fluidized classification chamber is provided so as to be movable up and down. 3. A coal drying/classifying apparatus, characterized in that a hole whose opening area can be adjusted is provided in the middle of a partition wall that partitions the fluidized drying chamber and the fluidized classification chamber.
