Abstract:In view of the present situation that the ore grade of bauxite which decreases year by year leads to the increasing amount of red mud and affects the settling performance of the settling tank, and combining with the current production practice of the existing settling tank, this paper introduces the upgrading method and implementation steps of the central shaft feed system of efficient deep cone tank from venturi to chute type. The self-overflow of pipe be realized by using the height drop of settling tank, so that the overflow pump can be removed. Through the implementation of a specific plan, the purposes of reducing power consumption and improving the treatment capacity of the settling tank are realized.
