    Investigating the benefits of replacing hydrocyclones with

    Mar 15, 2020 Screens, which provide better separation efficiencies compared to hydrocyclones, have been attracted the attention of minerals industry for many years. However, low capacity in fine screening applications has limited the use of screens to classify the ball mill product in wet grinding circuits. In recent years, the separation efficiency of fine particles in a small footprint has been largely increased by the advances in high-frequency screening technology, thus increasing the use of screens
