Abstract:
A liner assembly mountable to a shell of a grinding mill, the shell being rotatable around an axis thereof. The liner assembly includes a number of wear plates, a number of lifter bars securable to the shell with the wear plates positioned between respective pairs of the lifter bars, and a number of fastening subassemblies. The liner assembly also includes a number of wear elements, each wear element being positioned at least partially in a liner portion selected from the group consisting of the lifter bars, the wear plates, and combinations thereof, for resisting wear of a leading intermediate portion located substantially between a leading face of the lifter bar and a lifter channel therein. The liner portion includes one or more liner portion body materials in which each wear element is at least partially embedded. The wear elements are substantially more abrasion-resistant than the liner portion body material.
Abstract:
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.
