Abstract
An experimental evaluation of the power requirements for simultaneous ultrafine grinding and drying of low-rank coals in a fluid-energy mill was undertaken. Two different lignites and a subbituminous coal were used in the study. Ultrafine grinding tests were conducted with air nominally at ambient conditions and with steam at temperatures ranging from 225°F to 488°F. It was found that the power required for grinding and drying increased linearly with the grinding medium temperature.
