摘要：

This study presents a method for determining the fractionation rate of clinker in the grinding process with ball mills, a parameter that defines the fracturing of the material and the particle size distribution function. In the paper, the kinetic model of the clinker granule crushing process was taken into account. In the grinding process, reducing the size leads to a growth of the particle surface, though at the similar period a partial growth in the dimension of the particles due to aggregation and cluster is also observed. In both cases, energy is lost. For this purpose, substantial survey is conducted to determine fracture rate values that underline the change in particle size distributions in order to find a method to stop this energy loss. Estimation of the differential equation parameters for grinding was carried out with specialized programs provided by the Matlab package, and the validation was performed for a set of experimental data.
