In a cell-to-cell type flotation machine the sanding problem is minimized, as the pulp is mixed in every cell as it passes through the feed pipe and impeller. In a conventional open-type machine, as the pulp progresses from one cell to the next, the coarser, heavi-er fractions tend to stratify or settle to the bottom of the cell.
