Abstract
An apparatus for measuring the composition of coal and mineral ores on-line, by bombarding a sample stream with low energy X-rays and measuring the characteristic X-rays fluoresced. The assembly is comprised of one or more X-ray generators mounted in a specific geometry with one or more silicon detectors. A representative sample of a flow stream is obtained from a sampling system. Sample presentation to the analyzer is done with a plow or a flow cell to obtain a uniform interrogation zone for the analyzer. Elemental analysis (Aluminum through Silver on the Periodic Table) of the sample is computed from calibration curves generated from a linear relationship with count rates under each peak. Sample presentation to the analyzer is done with a plow or leveling plate to ensure that material flows past the analyzer at a constant level. The elemental analysis is determined by measuring counts under the characteristic peaks fluoresced by various elements in an energy spectrum resolved with a multi-channel analyzer.
