PROBLEM TO BE SOLVED: To provide a system for continuously granulating waste gypsum which meets the strong need of a processing technique and an improved working environment for reuse of waste gypsum. SOLUTION: The system for granulating waste gypsum continuously comprises the following equipment installed in the order from the head of the system: (a) a crusher 1 for separating/removing paper from waste gypsum to be generated from construction debris; (b) a rotary screen 3 and a drying burner 2 for drying/screening paper-removed waste gypsum; (c) a sprayer 5 for spraying a solution obtained by mixing a gluing agent such as starch, a medicinal component such as bittern and a solvent such as water toward the dried waste gypsum particles having definite particle size; (d) a dryer 7 which is equipped with a baking burner 6 and bakes, dries and hardens the solution-absorbed waste gypsum particles; (e) a crushing/screening machine 8 for crushing lumps of the hardened waste gypsum particles to obtain waste gypsum particles having specific particle size; and (f) a bagger 9 for bagging the obtained waste gypsum particles having specific particle size.
