The position of the second point limit switch 13 is set so that the aggregated powder breaks along the division surface 45 before reaching the second point limit switch 13 from the position of the first point limit switch 12. . The change in load during that time is converted into an electrical change by the load converter 8 and displayed as a load signal, and the change in load over time can be recorded as an output signal from the output terminal 41 as necessary.
