Effect of Mechanical Activation Frequency on the Reactivity of Phosphate Rock Mixtures in an Impact Mill

Year: 2025

Type: article

Abstract: This article presents the results of an experimental investigation into the mechanical activation of a phosphate rock mixture using a single-rotor impact activator. The key indicators used to assess the effectiveness of activation were the content of water-soluble P2O5 and the heat of dissolution of phosphorite in hydrochloric acid. The obtained graphical data illustrate a clear improvement in these parameters with increasing rotational speed and frequency of mechanical impacts on the material particles. Analysis of the results revealed that both the content of accessible P2O5 and the heat of phosphorite dissolution increased by approximately 15-20% when the intensity of mechanical activation was enhanced under the specified grinding conditions.
