In a vertical roller mill, the material on the grinding disc is restricted by the air duct ring, but the side of the material between roller and disc is not restricted. In roller press, in addition to the restriction between the two rollers, side baffles will also be set on the sides of both ends of the roller, which will limit the side of the material bed of the roller press.
