The Radiometric Belt Scanner (RBS) measures the uranium ore grade on the main uranium plant conveyor belt and reports the ore grade to the control room.
In order to optimize the uranium mill metallurgy process it is paramount to control the uranium ore grade that goes to the plant. The RDS RBS is a microprocessor based radiation monitor that detects the gamma radiation emitted by uranium ore on the main plant conveyor belt. The measured gamma count is converted to uranium ore grade (ppm U3O8) and displayed on a two line LCD either in 1, 2 or 3 minute counting intervals.
The RBS contains a two line LCD, the pulse counter with a microprocessor, the amplifier/HV power supply board and a 20.5 mm x 200 mm long GM tube inside a water proof lead shielded enclosure.
The readability of the ore grade is +/- 1 ppm U3O8 and the lowest limit of detection is approximately 10 ppm U3O8. As the amount of ore on the belt is continuously monitored by electronic scales the gamma count rate is logged and transmitted by radio to the PC in the control room only if ore mass on the belt is within a required mass range.
