Abstract
A method for controlling the liquid stroke of a pneumatically driven jigging machine for the separation of mineral mixtures uses a jigging machine that consists of an air chamber and a jigging chamber with a jigging bed located above it. The stroke of the liquid in the jigging machine depends on the period of time the air is allowed into the chamber. The differential pressure between the air chamber and the jigging chamber as parameter for controlling the jigging machine is measured, and as a result, a much better opportunity for controlling will be achieved, and disruptions in the jigging bed are detected and can be counteracted.
Claims9
A method for controlling a liquid stroke of a pneumatically driven jigging machine for separation of mineral blends, whereas the jigging machine comprises an air chamber and a jig with a jig bed arranged above the air chamber and whereas the stroke of the liquid used in the jigging machine is dependent on an air inlet time into the air chamber, the method comprising the following steps:
- measuring a differential pressure between a pressure in the air chamber and a pressure in a liquid column in the jigging machine;
- and
- controlling the air inlet time against the measured differential pressure.
