PURPOSE:To enable automatic measurement, by arranging equipments three- dimensionally in a sample adjuster so that samples automatically flow in the order of process with an automatic control mechanism interlocking a sensor or the like while robots are set in a hot CO2 reaction unit to handle a series of works. CONSTITUTION:As a backet 1a where a sample is fed reaches the highest of an orbit 1b, it tilts to load a hopper 3 with a sample. At this point, the backet 1a hits a limit switch 1c to start a crusher 4 and a siever 5 and the sample in the hopper 3 is crushed while the oversize samples are returned to a backet 2a and the undersize ones are sent to a hopper 8 to waste. Eventually, the samples of the specified size only are sent to a dryer 7. Then, the samples are reduced to almost the specified weight with a reducer 9, the weight of each lot thereof measured with an automatic weighing device 10 and sent to a hot CO2 reaction unit with a belt conveyor 12. Then, a series of works such as insertion of reaction tubes into and withdrawal thereof from an electric furnace and weighing of the samples after the reaction are handled by a robot to enable automatic measurement. |
