Coal Disintegration by High-Pressure Waterjet: Final Report.

摘要

A data base was constructed to demonstrate the capability and mechanism of coal comminution by means of high-pressure waterjets. With the aid of the data base, two laboratory-scale grinding mills were designed, constructed, tested, and evaluated for the production of sub-75-micron coal particles. One of the mills, a rotating-disk mill with one fixed waterjet, showed promise for significant efficiency. 11 refs., 85 figs., 27 tabs.
