Abstract
The invention relates to a process and an apparatus for the treatment of a material in the form of fragments or particles which is moved and/or rotated, mixed, heated and, if appropriate, comminuted by at least one mixing element () in a receiver or cutter-compactor (), where, in the course of the process, undesired substances which impair the treatment of and/or further operations on the material are removed from the material by introducing a gas, in particular air or an inert gas, in a region below the level of the material located in the receiver () during its operation, or below the level of material of the mixing vortex which forms within the receiver (), where the gas is forced to flow through at least a subregion of the material, and where the gas then saturated with, or with an increased concentration of, undesired substances is discharged from the receiver () in a region above the level of the material located in the receiver () during its operation or above the level of the material of the mixing vortex.
