PROBLEM TO BE SOLVED: To provide a quantitative supplying method for crushed waste capable of reducing load of an operator by automatically and properly maintaining a storing level, even if bulk specific gravity of a stored object within a hopper fluctuates, and maintaining supply amount to equipment on a downstream side and forming quality. SOLUTION: This method is one for supplying the stored object 11 to the equipment 16 on the downstream side by adjusting the number of revolutions of a screw 15, while maintaining a storing level LX of the stored object 11 within the hopper 12 to a proper range. When the storing level LX is between a lower limit level LL and an upper limit level LH, the number of revolutions of the screw 15 is left as it is. When the storing level LX is less than the lower limit level LL, the number of revolutions of the screw 15 is reduced according to a volume decrease ratio of the stored object 11 per time. When the storing level LX exceeds the upper limit level LH, the storing level LX is automatically controlled to be maintained between the lower limit level LL and the upper limit level LH by increasing the number of revolutions of the screw 15 according to a volume increase ratio of the stored object 11 per unit time.
