A rotary drum filter comprising one or more divider plates disposed between the drum's outer surface and grids disposed radially outward from the drum's outer surface. The divider plates are desirably diagonally disposed along the drum's outer surface and have at least one end disposed near a drainage hole. The divider plates and open sections under the grids between circumferentially adjacent grids permits filtrate to flow under the grids. The divider plates and open sections under the grids permit the filtrate to flow into the nearest drainage hole while increasing the run underneath the grids, thereby permitting more filtrate to exit through a limited number of drainage holes.
A refiner includes two or more facing refining assemblies. Each refining assembly includes a backing structure and refiner plate segments engaged to the backing structure A series of alternating bars and grooves defines a refining surface on each refiner plate segment. The refiner plate segments of the first refining assembly have a terminal edge perimeter defined by two or more terminal edges of bars disposed closest to the outer arc of the substrate of the first refining assembly. The refiner plate segments of the second refining assembly have an outermost edge circumference defined by an outermost terminal edge of a bar disposed closest to the outer arc of the substrate of the second refining assembly facing the first refining assembly. The terminal edge perimeter of the first refining assembly is not parallel to the outermost edge circumference of the second refining assembly.
