摘要：
Mechanical ball milling significantly enhances the recovery rate and utilization efficiency of phosphogypsum (PPG). This study investigates the mechanical activation of PPG. Mechanical ball milling was conducted at a speed of 300 r/s for periods ranging from 30 to 120 min. The particle composition and structure of activated PPG were analyzed using laser particle size testing. The grinding kinetics mechanism was analyzed based on classification theory, and its chemical activity was characterized through activity index testing. Results indicate ...
