The Test Installation Research On The Cement Crude Material Multi-ultimate Analysis Using The 2.5MeV Neutron

In the cement industry, the primary concern is quality control. Controlling the reasonable and stable crude material ingredient is the main essential link during the cement production, which has the vital significance to produce the high grade cement. The earlier the cement industry can institute quality control upon their product, the more significant their savings in labor, energy and material. Until now, the people still used conventional chemistry sampling analysis method to obtain these 3 rate values: Lime saturation coefficient KH, silicic acid rate n and the iron rate p. But the chemical analysis method speed is slow, cannot promptly instruct the production. However, the nuclear technology method can provide a new method to realize the cement analysis at the right moment because of its radiation penetrability. The neutron induced instantaneous gamma beam analytic method (NIPGA) may fast carry on the cement crude material analysis. It can produce [ n, Gamma ] response With 2.5MeV neutron irradiation to cement sample, and produce the instantaneous gamma beta spectrum through the element Si, Al, Fe, and Ca, which may obtain each kind of oxide compound content in the cement by calculation, thus calculates the cement lime saturation coefficient KH, silicic acid rate n, iron rate p. The pulse neutron generator has fast opens - closes the ability, enhanced the survey signal to noise ratio greatly, therefore it suits this method extremely.This article introduced makes the neutron source using the D-D neutron generator to carry on the cement crude material multi- elements content detector set the research. Compared after several kind of plans designs installment to tests, designs the field using detector set, installed makes the outer covering with the polythene, installed with wheel in the frame;The frontage has established the delievery crude entrance;the BGO detector installed in the installment from the side,which was put in the refrigeration systeme vaporator and the heat preservation with Dewar's flask.Carries on the characteristic with 2,048 spectrometers gathering gamma-ray spectrum gamma. Picks the water used to make the testinstallation the overall shielding material, because in the water theelement produces the characteristic gamma-ray, treats to thecement crude material in measured the element gamma-ray disturbsslightly, measured in the cement crude material the elementcharacteristic peak is obvious, but precisely calculates in the cementcrude material each kind of oxide compound content. Used thisequipment separately to carry on the cement crude material single component raw material and to enter rubs mix raw material the examination, and with chemistry chemical examination value comparison, the examinationresult was looking up in by mistake the permission scope.Because the neutron examines the measurement analysis speed to be quick, may achieve prompt adjustment delivery material mouth each kind of oxide compound the supplies quantity, thus enhances the cement the production quality.
