2022330 · Screening is an important part of mineral processing. In this paper, a large-scale dry screening method (the 0.8 mm classification of linear vibrating flip-flow screen) for spodumene is proposed, which break through the lower limit of traditional large-scale dry deep screening. First, the kinematic characteristics and spatial trajectory of ...
