The processor connection, the snifting valve is arranged on the surface of the turntable, and the barricade is arranged on two adjacent measurements
Between region, the barricade is stereotype, and each measured zone includes multiple pressure sensors, and the nuclear radiation is visited
The center that device is arranged on the multiple pressure sensor bottom is surveyed, the ore storage bin is connected with the shocking feeder, described
Shocking feeder is connected with the conveyer belt, and the ore storage bin is configured as storing ore to be sorted, the shocking feeder quilt
It is configured to the ores lifting to be sorted in the ore storage bin to the conveyer belt；
The conveyer belt is configured as ore to be sorted being sent to the measured zone of the turntable surface；
The turntable is configured as the carrying ore to be sorted and rotated；
The nuclear radiation detector is constant relative to the position of the ore to be sorted of the turntable surface, is configured as detecting institute
The radioactive intensity of ore to be sorted is stated, the radioactive intensity that measurement is obtained is sent to the processor, the nuclear radiation
Detector is measured by the way of multiple tracks measurement to gamma ray；
The pressure sensor is configured as the quality of the measurement ore to be sorted, and the quality that measurement is obtained is sent to institute
State processor；
The processor is configured as treating that the quality of sorting ore calculates the ore deposit to be sorted according to preset algorithm according to
The corresponding radioactive intensity reference value of stone, the processor is additionally configured to be treated point by described according to multiple pressure sensors
The pressure condition of the ore of choosing calculates the ore to be sorted in the measured zone relative to the nuclear radiation detector
Position, according to default correcting algorithm, is visited according to the ore to be sorted in the measured zone relative to the nuclear radiation
The radioactive intensity that the position of survey device is detected to the nuclear radiation detector is corrected；
The processor is additionally configured to the nuclear radiation detector inspection after radioactive intensity reference value described in comparison and correction
The radioactive intensity of survey, when the radioactive intensity that the nuclear radiation detector is detected is higher than the radioactive intensity reference value, institute
State processor and judge that the ore to be sorted is concentrate, when the radioactive intensity of nuclear radiation detector detection is less than described
Radioactive intensity reference value, the processor judges that the ore to be sorted is mine tailing；
The snifting valve be configured to respond to the processor control blowed to judged result for the ore to be sorted of concentrate
On to the concentrate transport belt, blowed to judged result for the ore to be sorted of mine tailing to the mine tailing conveyer belt.
