A rail seal for sealing the gap between a rail and a concrete panel in a railroad crossing so as to provide a generally even or level surface for vehicular or pedestrian traffic while still providing an appropriate rail structure for receiving and guiding the train wheels along the tracks is provided. More particularly, the upper surface of the rail seal is formed with a recessed portion or flangeway for receiving the flanged-end of a train. The flangeway or recessed portion, however, is formed so that the surface of the flangeway lies in a plane above the bottom of the rail head but below the upper surface of the rail head, thereby providing a "shallow" flangeway. The provision of a "shallow" flangeway helps to reduce the risks associated with vehicular and/or other pedestrian traffic that must access or cross the railroad tracks. Specifically, the shallow flangeway helps to prevent the heels of pedestrian shoes or the smaller width bicycle, stroller or wheelchair wheels from becoming trapped in the gaps typically associated with railroad crossing structures.

The discharge end liner includes a number of pulp lifter elements mountable on the discharge end wall for at least partially defining a number of chambers rotatable in the predetermined direction respectively between a submerged condition and a raised condition. The discharge end liner also includes one or more grate subassemblies positionable on the pulp lifter elements, for at least partially screening the slurry. At least a part of each grate subassembly is located by an outer portion of the pulp lifter element in a predetermined position relative to the discharge end wall. An inner portion of each pulp lifter element defines an obtuse angle between the inner portion and the outer portion, for permitting the retained portion of the slurry to evacuate from each chamber respectively while each chamber is in the raised condition.
B02C 17/04 - Disintegrating by tumbling mills, i.e. mills having a container charged with the material to be disintegrated with or without special disintegrating members such as pebbles or balls with unperforated container
A discharge grate assembly for at least partially guiding slurry from a mill shell chamber in a rotating mill shell to a discharge trunnion thereof via a pulp lifter chamber. The discharge grate assembly includes a body having a number of apertures for permitting the slurry to flow from the mill shell chamber into the pulp lifter chamber. The discharge grate assembly also includes a number of louvers movable between a closed position, in which the apertures in the body are at least partially covered by the louvers,
and an open position, in which the apertures are at least partially unobstructed by the louvers.
