- Аннотация: The paper addresses determination of ore hardness and grindability parameters using thedata obtained from the industrial comminutions circuits survey campaigns. The calculations use theearlier obtained relations between the high-energy impact fracture parameters A and b from JK DWTand SMC tests and the energy efficiency indices used in the Morrell method for the conventionalgrinding, coarse grinding and high pressure grinding roll milling. Using the simulation modeling ofcomminution circuits for two types of sulfide copper–nickel ore and one type of apatite–nephelineore, it is shown that the relative error of the theoretical determination of the JK DWT and SMC testingdata is never higher than 16.1%. The calculation method is recommended for application in designand optimization studies of process plants for various genesis minerals, including iron ore.
