Carbon materials represent difficult chemical compounds [1, 2]. They demand not only dispergating (crushing), and dehydration (removal of moisture) [3], but also cleanings of harmful impurity which negatively influence the environment at their further use in the industry. Now there are many installations and techniques of dehydration and dispergating of rheological material, including coals of different types. Comparative analysis of standard technologies and technology of thermal vacuum dehydration and dispergating of brown coal carried out. The experimental technique of dehydration and dispergating of brown coal described. Temperature, pressure, time of dehydration and dispergating of brown coal are determined. The physical model of simultaneous dehydration and dispergating of fine porous material offered. Dispergating of the dried-up material described by means of two models of disintegration of a part in the course of drying: discrete and continuous. It shown that at the initial stage of drying the maximum difference on the mass of the extracted water calculated on two models makes size about 7%. On big times of drying dependence of amount of the extracted water on time for the models considered above is almost identical. Calculations show that rapid withdrawal of water from a sample explains rather intensive process of crushing of the dried-up material at the initial stage of drying. At the same time with excess of temperature of the heater by 1.68 times over temperature of boiling of water with the lowered part pressure in the same number of times are crushed quicker. Comparison of theoretical calculations with experimental data shows adequacy of the offered models of dehydration and dispergating of fine rheological material.
