Claim:
1. A mineral material processing plant comprising: a frame; a crusher supported by the frame; a sub-frame supported by the frame; a screen supported by the sub-frame; and a first conveyor and a second conveyor having an operation position and arranged to discharge material fed into the plant to the screen when the first and second conveyors are in the operation position; wherein the first conveyor and the second conveyor are separate conveyors connectable successively in a transport connection; the first conveyor is movable to a transport position located to a first side of the crusher; the second conveyor is supported above the screen to the sub-frame; the transport position of the first conveyor is substantially within a transport height defined by the highest point of the crusher; the sub-frame is supported to the frame by first support arms and second support arms which form first four-bar linkages together with the frame and the sub-frame so that the second conveyor is movable with the screen to a transport position located to a second side of the crusher; and a third support arm and a fourth support arm which third and fourth support arms are fixed at a distance from each other and pivotably at second conveyor pivot points in connection with the second conveyor above the screen and pivotably at screen pivot points in connection with the screen, forming a movable second four-bar linkage that forms a movable support for the second conveyor; the second conveyor being arranged to move farther from the crusher and closer to the crusher by the movement of the second four-bar linkage such that the first conveyor is arranged in its operation position to feed the crusher or the first conveyor is arranged to feed in its operation position the second conveyor above the crusher for feeding the screen; the transport position of the second conveyor is substantially within the transport height defined by the highest point of the crusher.
