Suspensions, which usually contain slurries of various sizes of particles, which can settle quickly in a short period of time and contain a large amount of unavoidable interfering bubbles inside, so automatic unattended sampling and measurement of such suspensions is very difficult. However, sampling and measurement of suspensions plays an important role in online grade analysis in mineral processing control. Based on the above problems, this paper proposes an on-line analysis and prediction algorithm for suspension based on X-ray fluorescence analysis. Based on this, a large-scale online analysis system for slurry suspension is developed, which is successfully applied to the analysis of slurry grade in mineral processing control process. Unlike other liquids, mud does not allow for complex and slow process sampling and inspection processes. Since the mud detection accuracy is easily affected by the physical form of the slurry, the detection process must ensure transientity. It can be seen that the process sampling and mixing of the slurry is another key technology. In this paper, BOXA team finished simulation and experiment for primary sampling, secondary division and slurry carrying in cell based on CFD (Computational Fluid Dynamics) fluid simulation technology and analysis it, the laboratory and industrial data shows that sampling technique of BOXA can handle the slurry into standard state rapidly and steadily to ensure accuracy and reliability for the accuracy of assay and measurement.
