ABSTRACT:
A nuclear jig control unit which is an electronically controlled system employing nuclear sensing devices and electro-hydraulic operators to proportionally control the opening and closing of a refuse gate of a jig. These components permit remote operator control and monitoring of the jig. The system provides for immediate adjustment of the specific gravity setting which triggers refuse discharge. This allows complete removal of the built-up refuse yet minimizes inadvertent coal losses with the refuse.
