The study proposes mathematical model for reducing the size of mineral particles in crushing and grinding operations, which is a form of the reflected normal Gaussian – Laplace distribution. The study considers the distribution density modification of the mineral particles depending on the magnitude of the energy impact during grinding. Comparison of the results of computational experiments with the results of laboratory studies confirms the possibility of using the proposed model of disintegration of mineral particles in the development of software modules for the operational evaluation for crushing and (or) grinding of mineral raw materials.
