Coke powder is utilized as emaciating agent and mixed in coal during coal blending for cokemaking. This not only solves the coke powder sale problem and reduces environmental pollution, but also saves large amount of lean coal to realize the secondary utilization of energy. The applications of coke powder preparation processes and technologies in production are described. The five coke powder preparation processes of dry process, wet process, lubricating grinding, vibrating rod mill and high pressure roller mill are narrated respectively and the advantages and disadvantages of the five coke powder preparation processes and equipment are analyzed and compared.
