Exploration of Cyclone in Secondary Classification of Iron Ore Concentration
Through analyzing the traditional secondary grinding classification process of iron ore and its problems,the factors and conditions that affect the process are explored,and the necessity of introducing cyclones for pre-classification and high-frequency screens for control classification is proposed.The appli-cation shows that the cyclone provides suitable feeding conditions for the high-frequency vibrating screen,improves the screening efficiency of the vibrating screen,and at the same time improves the grinding effi-ciency of the ball mill,which to some extent increases the yield of concentrate.
