HPGR (high pressure grinding rollers), roll/roller crushers, or mineral sizers use two large rollers or a roller and a flat surface. The rolls can be serrated, toothed, or smooth. Vertical impactors use the weight and friction of the feed (autonomous) or add hammer-like processors. Horizontal shaft impactors spin feed against various surfaces.
