The coil classifiers are flow classifiers in which the process of separation of grains into fractions differentiated by their grain size occurs in the stream of the medium and the separation feature is a characteristic velocity of grains movement in relation to the medium which is the function of their size. The multi-parameter capacity of the system of conditions of the classification process course makes up for serious difficulties in constructing of this model. The paper presents an attempt of identification of significant conditions out of these in which the process takes place. The authors separated groups of factors affecting the course and results of classification and described their role in forming the technological indicators and separation characteristics. Also a scheme of construction of a phenomenological model of classification which can be considered to be sufficient for practical purposes, especially for the tasks connected with the regulation and controlling of the operation of coil classifiers in industrial conditions.
