    Automated Mineral Sample Preparation Of Coal Mine

    What Is Coal Preparation • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.Oct 07, 2021 The reason is that the difference in the bedding structure of the coal sample and the coal sample preparation process have caused some large pores to evolve into large cracks. Figure 7 shows that the proportions of the pore diameters of different bedding high-rank coals are different. Among the proportions of micropores, ZM5 is the highest at.
