Elemental Analyzer (EA)

Elemental Analyzer (EA) features one cross-belt type online detecting device for cement materials.

It is mainly used for online detection of element (composition) contents during limestone batching,raw mix.

EA is a modular structure and can be installed around a belt without the necessitytocut it.When EA operates, the belt slides through the internal supporting tank of the measuring unit and then EA measures all the materials passing by. During the whole detection process, no material is contacted and there is no influence on belt operation. When using EA, the measuring results are given once every minute, with the contents of eachelement and related quality control parameters being analyzed accurately.

Effective control over the production process can be made according to the real-time detecting information from analyzer to improve the production process, reduce the production cost and improve the product quality .

EA adopts prompt gamma neutron activation analysis (PGNAA) technology.

Fast neutron with an average energy of 2.35MeV is released from a neutron source. The fast neutron is moderated into thermal neutron by the measuring device, and the thermal neutron irradiates the material and occurs thermal neutron capture reaction with all elements in the material, emitting different gammarayswith different energy and intensity. By testing the energy in characteristic gamma rays, the element categories in the materials can be distinguished, and by testing the intensity of gamma rays with specific energy, the content of elements can be got. When the detector receives gamma rays, pulsed light will occur, which will generate electric pulse after entering into the photoelectric multiplier. The electric pulse is magnified by electronic signal processing parts and converted through ADC, and then a recombined gamma ray energy spectrum is generated. Afterwards, the element (components) of such an energy spectrum can be disclosed by microprocessor and advanced analysis software.
