A mineral material processing plant includes a frame, and a crusher and a screen which are supported on the frame, and a conveyor which is, in an operation position, arranged to discharge material which is fed into the plant to said crusher or screen. The conveyor includes separate first conveyor and second conveyor which are connectable successively to a transport connection, and the first conveyor is arranged to be moved to a transport position mainly to a first side of the crusher, and the second conveyor is fixed above the screen to be moved with the screen to the transport position mainly to a second side of the crusher. A method for operating a processing plant is also disclosed.

Mineral material processing plant and a method for operating a processing plant

A mineral material processing plant includes a frame; a crusher; a centrifugal conveyor; and a first conveyor; and the centrifugal conveyor includes a first idler drum and a second idler drum and a main conveyor belt surrounding the idler drums, a pivot and a folding head which is pivotable around the pivot; and the folding head includes a movable frame to which the second idler drum is bearing-mounted, to connect the centrifugal conveyor in material transport connection with the first conveyor and away from said material transport connection. A pivot point of the pivot is located in a region inside the circumference of the main conveyor belt. A method for operating a processing plant is also disclosed.

A mineral material processing plant includes a mineral material processing apparatus and a first conveyor which is arranged to feed the processing apparatus during operation of that processing apparatus. The first conveyor includes a first material transport part, a second material transport part and a pivot by which the second material transport part is fixed in relation to the first material transport part. The first conveyor is pivotable to an operation position in which the transported material is arranged to be fed via a discharge end of the second material transport part to the processing apparatus and to a service position which is in a first pivoting direction in relation to the operation position. In the service position, the projection of the discharge end of the second material transport part is arranged to leave free the lifting center of the processing apparatus when viewed from above. A method for operating a processing plant is also disclosed.

A mineral material processing plant includes a frame and a screen which is supported on the frame of the processing plant, and a conveyor which is fixed in connection with the screen for transporting material to be processed by the screen. The support of the conveyor relative to the screen includes a four-bar linkage mechanism, and pivot points of the four-bar linkage mechanism are arranged in support arms which are fixed pivotably in connection with the screen, and the conveyor is arranged to be moved further from the screen and closer to the screen by the movement of the four-bar linkage. A method for operating a processing plant is also disclosed.
