Popis: The paper deals with issues related to expanding the possibility of using a promising direction for improving vibrating cone crushers of secondary and fine crushing. The paper deals with two major issues that need to be solved at designing and creating vibrating cone crushers. First question: the value of the ratio of the crushing force in the standard design of a cone crusher of secondary or fine crushing. The second question is the frequency of forced oscillations of the additional vibration device. The choice of the ratio of the crushing force and the value of the driving force of the vibrator is based on the output of the rational frequency of forced oscillations of the unbalanced vibration device. For the first time in this paper for this type of machine the method of dividing the circular crushing chamber into separate sections is used. Each section is a zone of wave displacement of the compressive stress in the material from the action of the crushing force. The length of the section is considered in the range of the current action of the crushing force, in which the stress in the crushed material changes from zero to maximum and again to zero. This section of the action of the crushing force is an elementary section of the force effect of the crushing force on the material. The paper contains some new terms that are caused by the need to apply a more accurate description of the kinetics of the process. The paper forms new approaches to the process of calculating the parameters of vibrating cone crushers, so it can be considered in the “in order of discussion” format.
