The ETI Full Stream Elemental Analyser from HMA INSTRUMENTATION is a registered nuclear gauging device for measuring ash, moisture, and sulphur weight percent, heating value, and the ash elemental weight percent of coal. The measuring portion of the device, which consists of a source and detector enclosure, is mounted such that a conveyor belt passes through the enclosure. The detector is connected to an electronics enclosure housing an industrial computer that processes the detector signals and displays the measured results to the operator.

Real-time measurement of coal ash weight percent and a virtually unlimited flow capacity make the ETI Full Stream Elemental Analyser from HMA INSTRUMENTATION an invaluable sorting instrument. Run of mine coal, especially within highly variable seams, can be sorted efficiently into specific market products, thereby reducing good product waste and improving profit margins.

Application of the ETI Full Stream Elemental Analyser from HMA INSTRUMENTATION as the control element in either feed-forward or feed-back control topologies makes it an important tool for coal blending. Electronic control signals can be used to adjust feed rates from various coal sources, thereby improving blend quality and efficiency. On the output of a prep plant it allows for closed-loop feedback to control heavy-media density in the coal circuit. On a plant bunker feed belt, the ETI Full Stream Elemental Analyser from HMA INSTRUMENTATION allows for boiler operation adjustments to reduce boiler fouling and slagging, which can improve the long-term heat rate.
