· This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground Once the ore has been crushed it is diverted to a stockpile The aim of this step is to ensure a smooth crushing process and minimize downtime in the event of a breakdown or to allow planned maintenance in the crushing system without stopping the grinding and other further steps
Grinding is continuous and fully integrated with subsequent flotation operations SAG or AG mills The crushed products are ground in SAG or AG mills The self grinding machine can grind ore without grinding media such as iron ball or steel rod as long as the hardness of the ore is sufficient for the rolling ore to grind by itself
