Method for controlling a jigging machine

METHOD FOR CONTROLLING A JIGGING MACHINE Abstract The invention is for a method for controlling the liquid stroke of a pneumatically driven jigging machine (10) for the separation of mineral mixtures whereas the jigging machine (10) consists of an air chamber (20) and a jigging chamber (15) with a jigging bed (152) located above it and whereas the stroke of the liquid in the jigging machine (10) depends on the period of time the air is allowed into the chamber (20). The invention proposes to measure the differential pressure between the air chamber (20) and the jigging chamber (15) as parameter for controlling the jigging machine (10). As a result a much better opportunity for controlling will be achieved, whereby disruptions in the jigging bed (152) are detected and can be counteracted.
