1. Product Overview Ash Analyzer (AA-X) can be installed directly on the belt sampler and can online test the coal ash on the sampler. 2. Product Principle The product combines the principle of X-ray fluorescence and X-ray absorption. Applying X-ray exposure to the coal sample, the intensity of the different energy will be measured, and the coal ash value was calculated through data analysis and processing. 3. Product Parameter 1) Measurement accuracy ■Ash content <15%, standard error <0.5% ■Ash content 15~30%, standard error <1.0% ■Ash content >30%, standard error <1.5% 2) Operating environment ■ Ambient temperature: - 35 °C ~ 45 °C ■ Relative humidity: <98%, no condensation.

■ Power supply: three-phase AC 380V, 50 Hz, earthing resistance < 4 Q. 4. Product Features ■ The X-ray tube is used to replace the radioactive source and when without power supply, there is no radiation. ■ Measurement is not affected by particle size and density. ■ Real-time online nondestructive testing of coal ash. ■ Non-contact measurement. 5. Product application AA-X can be widely used in coal mines, coal washery, coal mixing plants, coking plants, coal-fired power plants, steelworks and coal docks, etc.
