Columns may be vertically baffled in order, both to reduce mixing and to lend additional structural support. An important condition to achieve effective operation with a baffled column is an even feed and air distribution between the compartments, otherwise detrimental circulation patterns may form between the baffled sections. This overall circulation can make a baffled column less effective in terms of flow structure than a column without baffles. Normally, baffles are installed above and below the feed distributor in a column, leaving space around feed pipe(s) and air spargers open to allow even distribution of the slurry and air bubbles, respectively.

Horizontal baffles (plates) are not typically used, though tests have confirmed their ability to improve flotation of coarse particles due to less short-circuiting in the wall part of the baffled column.
