Comparing strategies for grinding itabirite iron ores in ...
2021-3-15 Finally, more recently, the full secondary pre-crushing of the fresh feed to the mill has also been considered a valid alternative to improve throughput of SAG mills (Siddal and Putland, 2007). Their low competence, with drop weight A*b indices of over 100, has led to some doubts regarding the suitability of itabirite ores to AG/SAG milling.
