Abstract
This invention provides an ore separating device of the rotating wheel type that includes a container, which may be of fiberglass, having a concave portion and an annular flange at its periphery with a pad having ridges on its outer surface complementarily overlying the concave portion and removably secured by fasteners. An annular rim complementarily overlies the peripheral portion of the container and is removably held therein by forwardly inclined vanes which agitate the ore during rotation of the container.
Claims17
An ore separating device comprising
- a shallow container having
- a first concave portion with an opening at its center
- and a peripheral flange portion projecting from the outer edge of said first portion,
- means for positioning said container with its axis at an angle to the horizontal,
- means for rotating said container about its axis in a predetermined direction,
- a liner for said first portion,
- said liner defining spiral outwardly facing ridges on one side thereof,
- removable fastener means engaging said liner and said first portion for holding said liner in said first portion,
- an annular rim member complementarily overlying the surface of said second portion adjacent the periphery of said liner,
- said annular rim member engaging the peripheral edge of said liner for retaining said peripheral edge of said liner in said first portion,
- and a plurality of spaced vanes on said peripheral flange portion for causing agitation of ore in said container upon rotation of said container about its axis in said predetermined direction.

For use in an ore separating device comprising
- a shallow container having a first concave portion with an opening at its center and a peripheral flange portion projecting from the outer edge of said first portion,
- means for positioning said container with its axis at an angle to the horizontal,
- means for rotating said container about its axis in a predetermined direction,
- the improvement comprising:
- a liner for said first portion,
- said liner defining spiral outwardly facing ridges on one side thereof,
- the liner adapted to receive removable fastener means engaging said liner and said first portion for holding said liner in said first portion,
- an annular rim member for complementarily overlying the surface of said second portion adjcacent the periphery of said liner,
- said annular rim member adapted to engage the peripheral edge of said liner for retaining said peripheral edge of said liner in said first portion,
- and a plurality of spaced vanes on said peripheral flange portion for causing agitation and classification of ore in said container upon rotation of said container about its axis in said predetermined direction,
- whereby, said liner is easily and quickly attachable to and detachable from said first concave portion so that the ore separating device can be adapted to different ores or so that the liner if worn can be readily replaced.
