1, randomly draw lime or the light dolomite sample that a certain amount of particle size range is evenly distributed in each grade of 30-70mm, and guarantee that lime or light dolomite sample have certain representativeness on grade;
2, with balance, lime or light dolomite sample are weighed, obtain the weight of lime or light dolomite sample;
3, the lime after weighing or light dolomite sample are packed in thin plastic packaging bag, seal after evacuation of air, again lime or the light dolomite sample plastic packaging bag of sealing are put into respectively measuring tank after being filled with water, measure one by one the volume of lime or light dolomite sample;
4, according to the weight and volume of step (2), (3) detection, calculate respectively the volume density of each lime or light dolomite sample;
5, use fluorescence detection to detect the CaO content of each lime or light dolomite sample, detect at least 2 points at every turn;
6, in on-the-spot a period of time of intercepting, lime or the light dolomite of actual production is in kind, the intercepting number of times repeats more than 100 times, lime or light dolomite to each grade detect respectively according to step (1)-(5), use MINITAB software to carry out data regression, obtain the corresponding relation of each sample CaO content and volume density, and make corresponding table;
7, the weight, volume and the volume density that step (1)-(4) are detected are applied to commercial production as foundation.
Beneficial effect of the present invention is:
The present invention is according to the corresponding relation of giving birth to stone in lime or light dolomite and decompose fully the size of rear grog volume density and its igloss, CaO, MgO content, extrapolate fast igloss, the CaO of grog, the physical and chemical index of activity degree, thereby the physical detection data of lime or light dolomite quality are provided for the production scene, for the quality control of production team provides reliable basis with in time instructing and adjusting the produced on-site technological parameter, guaranteed the stable control of product quality.Simultaneously, can avoid the manually-operated sampling and detect non-standard phenomena, simplifying the production scheduling program, increase work efficiency and manage the control level, guaranteeing the efficient operation of producing.
