PROBLEM TO BE SOLVED: To provide a solid aggregate measuring apparatus capable of holding density of a solid aggregate dropped from a charging port of an upper hopper and stored in a measuring container at fixed density and performing measurement based on always accurate volume.SOLUTION: A level sensor 23 respectively detects height positions of raw materials t1, t2, t3, t4 in upper hoppers 13, 15, 17, 19, and when the height positions are descended lower than a position of the level sensor 23, lamps 103, 105, 107, 109 are turned on. When the lamp 103 e.g. is turned on, an operator supplies the raw material t1 to the upper hopper 13 until the lamp 103 is turned off. Since the height (quantity) of the raw material t1 is held at almost fixed height in the upper hopper 13, load applied to the raw material t1 in the measuring container 59a is fixed and the density of the raw material t1 in the measuring container 59a can be fixed. Thereby, measurement based on the volume of the measuring container 59a can be always accurately performed. |
