Abstract
An automatic control for an electropneumatic wet settling machine, for the separation of mineral mixtures, in particular coal, through the pulsation of the separating liquid, provides that the separating liquid is energized and controlled by means of compressed air in pulsing chambers, and that measuring devices for measuring the movement of the separating liquid are provided to signal, advantageously on an analog basis, the movement of the separating liquid in order to control the introduction and exhaust of compresssed air from the pulsing chambers.
