Coal-sand attrition system and its importance in fine coal cleaning. First quarterly report, September 1, 1991--November 30, 1991
The primary objective of this project is geared toward the substitution of steel media by fracturing silica sand as a grinding media for ultrafine coal grinding. The experimental silica is as follows: (1) design and fabrication of attrition cell; (2) sample procurement, preparation, and characterization; (3) batch grinding tests; (4) continuous grinding test; and (5) fracture mechanics.
