Online Coal Ash Analyzer DF-5753 Online Coal Ash Analyzer
The Online Coal Ash Analyzer (DF-5753) is used for on-line detection, measurement and control of coal ash & finds wide application in coal mines, coal washing plants, coal blending plants, coking plants, coal-fired power plants, steel plants and coal terminal, etc. It is especially suitable for on-line coal ash analysis on the entire belt conveyor during the coal transportation process.
Working principle
On the basis of double energy γ ray absorption method, the coal ash content can be calculated by processing data of the two rays after passing coal attenuation.
