A mobile sizing station includes a crushing device and a hopper device. A conveyor device extends between a hopper of the hopper device to a crusher mechanism of the crushing device to transport material fed to the hopper to the crusher mechanism to crush the material. The hopper of the hopper device is supported on a base that has a plurality of frame members. A first frame member is pivotally connected to a second frame member and is also rotatably supported such that the first frame member is rotatable. The second frame member is pivotally connected to a third frame member and the third frame member is connected to the hopper. The hopper is thereby rotatable and is tiltable about the pivotal connections between the second and third frame members and is also tiltable about the pivotal connection between the first and second frame members.
