Simulation of operation of fine crushing cone crusher

The processes of crushing and grinding mineral raw materials are the most energyintensive technological processes, which consume about 20% of all electricity generated in Russia, therefore all studies aimed at increasing the efficiency of the crushing process are relevant. Reduction of energy consumption can be achieved by improving the quality of the output product, excluding pressing modes, which are achieved by matching the parameters of the crushers with the properties of the processed materials. The quality of the product will be "the best" if there are no pieces in the crushed product larger than the setting of the discharge gap. Known methods for determining the parameters of the working crushing zone in cone crushers are based on geometric constructions and determining the parameters under such assumptions, when the movement of the piece begins with a fully "open" crushing chamber, the initial position of the piece is not taken into account. In a real crusher, a piece falls from a certain height from the loading device before entering the crushing chamber and can enter at any moment, both when the crushing chamber is "opened" and when it is "closed". In order to exclude some assumptions and take into account the features of the work process, a simulation mathematical model of the technological process of breaking a piece of rock has been developed. The presence of an adequate model of the technological process of breaking a piece of rock, i.e. crushing, will allow solving the problems of matching the parameters of crushers with the properties of the processed materials.
