Study on Slaking Particle Distribution Characteristics of Carbonaceous Mudstone

Article Preview

Abstract:

In order to find out the slaking mechanism of carbonaceous mudstone, this study puts two different samples in the indoor soaking slaking test, one of dried sample and the other original one. After comparing the characteristics of carbonaceous mudstone slaking particles 's distribution under different moisture content conditions , the result shows: The main reason for carbonaceous mudstone slaking is the change of moisture content resulting from dry-wet circulation. The difference in moisture content partly affects the process and slaking product before slaking. The lower the moisture content is, the smaller the slaking particle diameter is and the more thoroughly the slaking is. As the particle diameter of the slaking product decreases, its slaking gradually weakens and even disappears.
