摘要
Coal particles, typically having a particle diameter below approximately one micron, are produced by mechanical fracturing, the addition of a swelling agent, the further mechanical fracturing and removal of the swelling agent. In particular, gaseous anhydrous ammonia is employed as the entrainment fluid and swelling agent in a fluid energy mill for coal comminution.
