As is known to all, the dressing operation consists of three stages: pre-dressing, dressing and post-dressing. The preparatory work before mineral dressing generally includes crushing and screening, grinding classification, hand sorting and washing, among which grinding classification is the follow-up technology of crushing and screening and also an important process in the pre-dressing stage.
