Sažetak

The paper presents coal comminution utilizing high-pressure water jet. Prototype of hydrojetting apparatus for coal disintegration with this method is presented. Three different types of coal were examined: hard-, brown-, and charcoal. Obtained results point out that high-pressure water jet usage for such purpose is very effective. Brown coal is more susceptible to this method treatment than the hard one whereas the most intensive disintegration is characteristic for charcoal. Such micronization effect gives even over 100 000 time's increase of its specific surface compared to normal fine coal after traditional comminution. Moreover, charcoal susceptibility for intensive hydro-comminution is the reason why one can get the most comminuted structure, this being a good prognosis for its modification into bio-fuels.
