A deck inlet for a sifter includes a pan and a spreader. The pan is oriented at an angle from about 2&#xb0; to about 20&#xb0; with respect to a horizontal plane. The spreader is coupled to or integral with an upper surface of the pan. The spreader is configured to spread a material substantially evenly across a width of the pan.

A housing inlet for a sifter includes a scalping screen sloped downward in a first direction. The housing inlet also includes a pan positioned at least partially below the scalping screen. The pan is sloped downward in a second direction that is different than the first direction.

An apparatus includes an outer bearing member defining a cavity and an inner bearing member disposed within the cavity. The inner bearing member includes a spherical surface and a rod attachment opening defined in the spherical surface. The apparatus also includes an elastomeric material disposed within the cavity adjacent to the spherical surface.

Spherical elastomeric mounts

Described herein are splitters for holding and distributing input material to one or more decks of a gyratory sifter, where the splitter distributes approximately an equal amount of input material to each deck. An exemplary splitter may include a bottom surface, a sidewall, and one or more openings through the sidewall. Each opening may include a plurality of slits, allowing input material to pass therethrough. Where multiple openings are provided through the sidewall, the openings may be evenly spaced and have an equivalent area. The bottom surface may be substantially circular, and the sidewall may extend perpendicularly from the edges of the bottom surface. An exemplary splitter may be able to receive and distribute the input material when a gyratory force acts on the gyratory sifter on which the splitter is installed.
