Description

Field of technology to which the invention relates

The present invention generally relates to a mobile mineral processing plant.

State of the art

The following will provide useful information regarding the state of the art, without describing any methodology that characterizes the existing state of the art.

Mineral material is processed by crushing or screening on mobile units that are self-propelled or towed. The mobility of such installations is increased by folding them to form a transport configuration. Patent document GB 2526769 A presents an example of a mobile screening plant for processing bulk material and, in particular, in a portable or mobile format. The installation, which complies with GB 2526769 A, contains a feed conveyor and a screen, which can be superimposed on each other and raised with their adjacent ends upward, as well as three outlet conveyors, two of which can be folded onto the screen, so that the entire installation can be largely Folded for easy transport. The folding side conveyors appear to be manually foldable and there are rectangular profile telescopic supports to hold the folding side conveyors in the folded configuration. The central outlet conveyor is installed motionless.

Disclosure of the invention

The object of the present invention is to improve the transportability of a mobile mineral processing plant, or to improve the operating configuration of a mobile mineral processing plant, or at least to provide a new technical alternative.

According to a first exemplary aspect of the invention, there is provided a mobile mineral processing plant comprising a mobile platform including tracks or wheels or skids. The installation differs in that it additionally contains:

a body supported or formed by the mobile platform;

supported by the housing in one line when the plant is in a transport configuration: feed conveyor, screen with several tiers for separating three or more different fractions of mineral material; a first outlet conveyor, a second outlet conveyor, and a third outlet conveyor on top of the first and second outlet conveyors;

a first rotating mechanism configured to rotate the first outlet conveyor from a transport position under the third outlet conveyor in a first operating direction to a first side of the mineral material processing plant for operating said mineral material processing plant, and back to a transport position for transporting the mineral material processing plant; And

a second rotating mechanism configured to rotate the second outlet conveyor from a transport position under the third outlet conveyor in a second operating direction to a second side of the mineral material processing unit opposite the first side, and back to a transport position for transporting the mineral material processing unit.

The advantage is that the feed conveyor and the first, second and third discharge conveyors can be rotated and aligned to form a compact transport configuration.

The first base portion may be less than 20% of the length of the first outlet conveyor. The first base portion may be less than 10% of the length of the first outlet conveyor. The first base portion may be less than 5% of the length of the first outlet conveyor.

The base portion of the first outlet conveyor may be located below the outlet edge of the screen.
