Hello everyone, I would like to know which one is efficient in iron ore crushing and grinding circuit: Jaw crusher+SAG mill+ ball mill 3 stage crushing + 2 stage grinding (ball mill) Regards, Suvd
This industrial scale study compares two grinding circuits operating in an iron ore process with a production capacity of 12 million tons per year. The plant has three identical parallel lines, all fed from the same feed pile. Each line has an independent grinding circuit, with two ball mills and three hydrocyclones batteries.
(Because of this requirement, closing a SAG mill with a crusher is not used in magnetic iron ore grinding circuits.) This circuit configuration is common as it usually produces a significant increase in throughput and energy efficiency due to the removal of the critical size material. An example SABCA circuit is the Cadia Hill Gold Mine, ...

Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates ecoefficient alternatives for the process design for magnetite iron ore.
