Mobile mineral material processing station
A mobile mineral material processing station has a mobile platform having tracks or wheels or a skids for supporting or forming a body that supports in line, in a transport configuration: a feed conveyor; a screen frame and a multi-layer screen; first and second exit conveyors; and a third exit conveyor on top of the first and second exit conveyors. The first exit conveyor turns from a transport position, under the third exit conveyor, to a first operation direction, onto a first side of the station, for operating the station, and back. The second exit conveyor turns from a transport position, under the third exit conveyor, to a second operation direction onto a second side of the station, opposite to the first side, and back.
1. A mobile mineral material processing station comprising:
a mobile platform comprising tracks or wheels or a skids;
a body supported by or formed by the mobile platform;
a feed conveyor;
a screen with multiple layers for separating three or more different fractions of mineral material;
a first exit conveyor;
a second exit conveyor;
a third exit conveyor, wherein the feed conveyor, the screen, the first exit conveyor, the second exit conveyor and the third exit conveyor are supported by the body in line with each other and the third exit conveyor is on top of the first exit conveyor and the second exit conveyor when the station is in a transport configuration;
a first turning mechanism configured to enable turning the first exit conveyor from a transport position that is in line with and under the third exit conveyor to a first operation direction onto a first side of the mobile mineral material processing station for operating the mineral material processing station and back to the transport position for transporting the mineral material processing station; and
a second turning mechanism configured to enable turning the second exit conveyor from a transport position that is in line with and under the third exit conveyor to a second operation direction onto a second side of the mobile mineral material processing station, opposite to the first side, and back to the transport position for transporting the mineral material processing station.
2. The mobile mineral material processing station of claim 1 , wherein the first exit conveyor includes a first base portion and a first discharge end, wherein the first base portion is fixedly mounted to the mobile platform and the first discharge end is pivotable relative to the first base portion.
3. The mobile mineral material processing station of claim 1 , wherein the second exit conveyor includes a second base portion and a second discharge end, wherein the second base portion is fixedly mounted to the mobile platform and the second discharge end is pivotable relative to the second base portion.
4. The mobile mineral material processing station of claim 1 , wherein a base portion of the first exit conveyor and a base portion of the second exit conveyor are located under a discharge end of the screen.
5. The mobile mineral material processing station of claim 1 , wherein the transport orientation of the feed conveyor is parallel with or at most 15 degrees off a ground line of the mobile platform.
6. The mobile mineral material processing station of claim 1 , further comprising a tilting mechanism configured to tilt the feed conveyor, the screen when mounted to the screen frame and the third exit conveyor from a compacted configuration to an extended operating configuration in which the feed conveyor slopes upwards, the screen when mounted to the screen frame slopes downwards and the third exit conveyor slopes upwards.
7. The mobile mineral material processing station of claim 6 , wherein the tilting mechanism is further configured to maintain the third exit conveyor at a distance from the screen that remains constant during the tilting of the third exit conveyor.
8. The mobile mineral material processing station of claim 6 , wherein the tilting mechanism is further configured to lift a screen-side end of the third exit conveyor on moving the third exit conveyor to the compacted configuration so that sufficient space is formed under the third exit conveyor for turning the first exit conveyor and the second exit conveyor to the transport position.
9. The mobile mineral material processing station of claim 6 , wherein the tilting mechanism comprises feed conveyor tilting arms.
10. The mobile mineral material processing station of claim 6 , wherein the tilting mechanism comprises third exit conveyor tilting arms.
11. The mobile mineral material processing station of claim 6 , wherein the tilting mechanism is configured to tilt the feed conveyor and the third exit conveyor by angles deviating at most 15 degrees.
12. The mobile mineral material processing station of claim 6 , wherein the feed conveyor tilting arms comprises a first sub-arm and a second sub-arm that are pivotably connected to each other.
13. The mobile mineral material processing station of claim 12 , wherein the first sub-arm is functionally connected to the screen frame to move with the screen frame.
14. The mobile mineral material processing station of claim 6 , wherein in the compacted configuration, feed conveyor, the screen when mounted to the screen frame and the third exit conveyor are in their respective transport orientations.
15. The mobile mineral material processing station of claim 6 , wherein the first operation direction is freely adjustable in a first adjustment sector.
