Option 2 has an additional grinding and magnetic separation stage compared to Option 1 and is considered to be simple for design and operation. The final milling stage is carried out using energy-efficient stirred mills. Steel grinding media usage significantly increases the operating cost. Option 3.
The pelletizing equipment produced by AGICO has high production efficiency and can save about 40% of energy. Our equipment has high wear resistance, long service life, and a nice appearance. The damp mill is a kind of ball grinding machine, widely applied in iron ore pelletizing plants. It can deal with semi-dry and semi-wet materials.
This work assesses the potential suitability of autogenous (AG) and semi-autogenous (SAG) milling through an extensive pilot plant campaign carried out with itabirite iron ores. The effects of ore type, feed size distribution, circuit configuration (open or closed-circuit and two-stage or single-stage), mode of grinding (AG or SAG), ball load ...
