Abstract
A control apparatus for a rotary valve-driven jigging machine for processing coal or other minerals, particularly for a rotary valve-driven throughput jigging machine whose pulse chambers periodically are charged with compressed air in order to generate a pulse motion and are disposed under the jig screen, is characterized in that the level of the working air pressure in the pulse chambers is changed as a function of changes of the size of the stroke of the separating liquid. The change of the level of the working air pressure in the pulse chambers occurs by a controlled throttling of the outgoing air and/or of the incoming air.
