PROBLEM TO BE SOLVED: To provide a method of pulverizing coal for the production of coke which can pulverize coal with precision without varying the formulation of raw materials and the target particle size. SOLUTION: In a repulsion type pulverizer 10 having a rotor 12 and repulsive plates 14 and 15, the relationship (V and P) between the set amounts V of the gaps 14a and 15a between the rotor 12 and the repulsive plates 14 and 15 and the variance P of the particle size of the coal after pulverization is previously found, and by regarding the difference between the measured particle size of the coal pulverized by the repulsive pulverized 10 and the target particle size after the previously set pulverization as variance P, the set amounts V are found from the relationship (V and P), and the gaps 14a and 15a between the rotor 12 and the repulsive plates 14 and 15 of the repulsion type pulverizer 10 are adjusted based on the set amounts V to effect pulverization of coal.
