Column baffles (1) for suspensions with-precipitating substances which are provided for a substance transfer between the suspension and a vapour phase-moving in a counter-flow. The baffles comprise membrane-like elements (2, 3; 5) which, on the one hand, bring about a cascade-like formation of liquid curtains with respect to the suspension and, on the other hand, with respect to the vapour phase, for chicanes for strong changes of direction for the vapour flow which lead to the formation of eddies in the vapour phase. In accordance with the invention, the membrane-like elements are made from a flexible material and are secured at few sites in the column (100) such that an oscillating movement or fluttering movement of the elements can be excited by the flowing media, in particular by means of eddies in the vapour phase.
