Abstract: A waterless system for processing mined material to remove impurities therefrom includes a dryer, a pulverizer, and an air classifier. The dryer is configured to remove moisture from a batch of mined material, such as coal, and the pulverizer is configured to pulverize the dried coal into small, individual coal particles and liberate impurity particles from the coal without substantially reducing the size of the liberated impurity particles. The dryer heats an air stream containing the coal to a temperature of between about 500° F. and 1,000° F. and includes a plurality of rotating paddles. An air stream forces the coal through the plurality of rotating paddles to pulverize the coal into small, individual particles and to liberate the impurity particles. The air classifier separates the impurity particles and pulverized coal particles into respective product streams. A pelletizer pelletizes ultra fine coal particles into pellets or bricks to facilitate handling and/or storage.
