Tests by the Bureau of Mines' Twin Research Center at Minneapolis, Minn., has shown that drying fine coal in the minus 1/4-in. range with microwave energy is not only feasible but also very efficient. The microwave technique, uses a custom-designed conveyorized microwave oven to dry three coal types: bituminous, subbituminous and lignite. Remarkable drying efficiencies of 97% for Colowyo coal of minus 1/4-in. plus 28 mesh, as well as for Illinois No. 6 coal of minus 28 mesh plus 100 mesh were obtained by the bureau using the pilot-scale continuous drying microwave system.
