Apparatus for contacting fused solid materials with solid, liquid or gaseous materials, comprising a rotary drum, longitudinal baffles along the inner drum wall inside the apparatus, coaxial consoles being joined in a liquid- and gas-tight manner to faceplates of the drum, for lodging feeding and removing mechanisms. It is a major feature of the invention that a diverter baffle system is mounted from the consoles throughout the interior length of the drum. Two preferred embodiments are described: one for formulating plant protecting agents, wherein the baffle system includes a row of diverting baffles that can be pivoted inside the drum. The other preferred embodiment is suitable for extracting vegetable materials, and here the baffle system is constituted by a stationary drum having a slanting lapping formed therein, similarly pivotable diverting baffles being arranged along the lapping. Various additional and some optional structural features are disclosed for both apparatus embodiments.
