When crushing, use a jaw crusher for primary crushing, and then use a cone crusher for fine crushing. When grinding, use a ball mill . As proper grinding fineness is crucial to the flotation results, the particle size of lithium ore generally needs to be ground to less than 0.15 mm for a better flotation effect.
