the selection of parameters for the working chambers and actuators. Works [9,10] provide recommendations for the design and manufacture of crushers for aluminum cans, which cannot be directly applied to rock crushers. The work in [11] proposes the design of a continuous crusher, but there is no mathematical model of its operation. At …

For selection of the best Area for Sungun development crusher, 14 criteria for five alternatives were checked. Results show that Area 3 (on the South East of Sungun current pit) is the best solution. Using MCDM methods have many advantages, but it is important to emphasize that the success of the method largely depends on the expert evaluation ...

The method developed for multi-criteria optimization of the crusher can be effectively used to optimize the parameters and structure of other types of crushing machines. Based on the results of the performed work, the authors elaborated an analytical expression for calculating the rational profile of the crusher working chamber.
