Rationalization of geometric parameters receptions bunkers primary gyratory cone crusher for automotive transport

Annotation: The article presents the results of studies of the influence of the geometric parameters of the receiving hopper of the crushing plant on its actual capacity. We consider bunkers in the form of a parallelepiped, designed for direct loading of a cone crusher located below it. The data were obtained on the basis of modeling the geometric parameters of the embankment in the bunker in accordance with the location of the unloading points and the carrying capacity of dump trucks. Many of the options considered are summarized in the form of two-dimensional and three-dimensional graphs.It is shown that for modern powerful crushing complexes with a capacity of 5000—8000 mt/h, it is rational to use two unloading points located on opposite sides; organization of three-sided unloading is excessive in terms of the crusher loading intensity and less efficient in terms of filling the hopper. The data on the influence of the length and width of the bunker on the occupancy, the degree of utilization of the geometric capacity are given. A rational range of the length and width of the bunker has been established for the considered range of carrying capacity of dump trucks, methods of increasing the capacity of the bunker by moving the unloading points towards the center of the bunker. The research data can be used in the design of crushing and reloading points of the CPT complexes, as well as receiving bunkers of concentration plants when loading by motor vehicles.
