Suggestion for selecting lithium ore grinding equipment We suggest using a ball mill or vertical mill for grinding lithium ore. By crushing the lithium ore in the previous step, the lithium ore and gangue minerals will separate to obtain particles that match the following beneficiation process. Suggestion for selecting lithium ore sorting equipment
The coarser ore being drier and having more space in between each piece than is normal, will not slow the flow of fine material towards the discharge points as much. This means that when the crushers stop putting ore into the fine ore storage the size ratio of the mill feed will decrease rapidly.
