Abstract—The use of a drum chute instead of the regular chute is proposed in coke sorting prior to classification. A method of calculating the optimal drum dimensions is outlined. The drum’s inclination is plotted as a function of the required number of drum rotations to which the coke is subjected. A simplified method is considered for determining the number of drum rotations to which the coke must be subjected in order to meet specified quality requirements.
