Bouchillon, C W; Steele, W G

The specific goals for Phase I of this project were to: (1) select a friable Texas lignite for Phase I investigation. (2) In three separate tests, micropulverize the lignite in a fluid-energy mill utilizing steam as the drying agent and carrier media to produce at three levels of moisture content. (3) Measure the power requirements to micropulverize the lignite at each level of product moisture. (4) Measure the product size distribution, ash content as a function of particle size, particle shape, angle of repose and moisture reabsorption. (5) Submit a technical report on the test lignite. Preliminary results are reported.
