PROBLEM TO BE SOLVED: To provide a rotary pan type granulator for obtaining granulated material excellent in strength and reduced in shaped products and to provide the method for producing the granulated material by using the granulator. SOLUTION: This rotary pan type graulator is provided with an inclined rotary pan 1 in which the feed of raw material powder and the dispersion of a liquid binder are performed and the raw material powder is transferred to aγpart 16, aβpart 17 and anαpart 18 from the bottom surface side in this order while being rolled to grow it into aggregated and granulated material, a distance displacement sensor 10 for measuring the layer height of theβpart 17 except the dispersed area of the liquid binder, and a control means 11 for controlling the dispersed quantity of the liquid binder and/or the fed quantity of the raw material powder according to a control signal from the distance displacement sensor 10. While controlling the dispersed quantity of the liquid binder and/or the fed quantity of the raw material powder according to the layer height of theβpart 17, granulation is performed.
