Abstract

A jigging machine, particularly a movable sieve jigging machine, for the preseparation of deads from valuable material comprises an oscillatory jig bed in the housing filled with separating fluid and comprises deads and valuable material discharge devices located therein, as well as an oscillatory drive for the jig bed. The jigging machine is suitable for underground mining operations in that the outer dimensions of the jigging machine, with respect to the height and width theeof, are designed smaller than the tunnel cross-section of an underground mining operation. A relatively low structure is achieved by designing the housing as a flat trough towards a deads discharge end with the deads discharge being provided as a rising conveyor parallel to the bottom of the trough. Advantageously it is achieved that the quantity of deads to be conveyed is reduced and a considerable saving is provided in terms of energy and expense.

Claims

1. An underground mobile jigging machine for separating a mixture of deads and valuable material in an underground tunnel, comprising:

a housing including a charging end and a deads discharge end, for holding a separating liquid;

a perforate jig bed pivotally mounted in said housing in the separating liquid for receiving the mixture thereon;

oscillating drive means, including a piston cyinder connected to said perforate jig bed for oscillating the mixture, and the separating liquid, to cause startification thereof with the valuable material on top of the deads;

a first conveyor communicating with the deads layer for conveying off the deads;

a second conveyor constructed as a screw conveyor communicating with the valuable material layer for carrying off the valuable material, said housing comprising a trough including a floor disposed at an upward angle, with respect to the horizontal, towads the deads discharge end, said first conveyor extending parallel to said floor;

mobile support means supporting said housing from movement along the foor of the tunnel;

a sump in said housing for receiving valuable material passing through said perforate jig during separation; and

pump means connected to said sump and communicating with said second conveyor to provide a hydraulic discharge of the valuable material from said second conveyor.

2. The underground jigging machine of claim 1, wherein:

the angle of said housing floor is in the range of 15°

to 25°

.

3. The underground jigging machine of claim 1, wherein:

the angle of said housing floor is 20°

.
