The kinetic theory oil agglomeration of coal has been studied by the agglomerate growth. It is assumed here that the oil collision of interaction between the coal dust and the dispersed bridging oil is the rate determining step. The second order kinetic equation with two constants describes the growth kinetics adequately. The effects of operating variables, such as furnace oil dosage, degree of agitation and feed size. The model accounts qualitatively for the observed experimental trends and provides a basis for under standing of the fundamental aspects of the agglomeration process.\;
