The present work analyzes the application of the UFRJ mechanistic ball mill model to grinding of iron ore pellet feed in an industrial grinding circuit. In order to address the challenge of applying the model to a reasonably fine feed, selected model parameters were back-calculated on the basis of batch grinding tests.
When the ore is ready to be processed, it flows by gravity into the facility onto one of 12 conveyors lines which brings the ore up a slope that feeds a primary grinding mill. Each of these 12 primary grinding mills then feed 2 peb-ble mills that further reduce the size of the material. After the ore exits the pebble mills and has been

Mar 15, 2021 In spite of the important advances in modelling and simulation of autogenous and semi-autogenous grinding made in recent decades (Napier-Munn et al., 1996, Morrell, 2004), risks exist in designing a circuit adopting AG/SAG mills for low-grade itabirite iron ores from bench-scale information.
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
