ABSTRACT:
A jigger for the processing of minerals such as coal, consisting of two traveling troughs, the upper trough being equipped with a sieve and closed from below by a continuous flexible membrane, the lower trough interrelating with the diaphragm of the upper trough, acting as a piston and giving water vertical pulsation. The troughs are linked to each other via double-arm levers, hinged in the supports. The double-arm levers together with the troughs form a system of hinged parallelograms, providing uniform distribution of pulsations along the whole capacity of the upper trough that produces conditions for the intensification of the jigging process. Besides this intensification, decreasing of energy-consumption and simplicity of design having been achieved. A laboratory sample was made and its testing showed good technological results and confirmed the reliability of a unit simple in manufacturing, operating and maintenance.
