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, system and method for fastening a screen has a screen with apertures sized to separate a first sized material from a second sized material. A box is positioned beneath the screen in a bracket extending along the screen. A protrusion extends from the box toward the screen. A triangular tensioning element secured along a length of the screen moves in a direction substantially perpendicular to the length of the screen in response to contact with the protrusion to seal the screen against the bracket and tension the screen.

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

An apparatus, system and method have a rod attached to and extending across a screen to engage with a receptacle. A box is positioned beneath the filtration screen. An air bag is activated to inflate the filtration screen to compress against a plate. A junction extends from the plate, and the air bag rises to move the junction toward the receptacle to compress the rod against the receptacle to hold the rod. The filtration screen may be constructed from mesh material sized to permit materials to flow through the filtration screen. A vibratory element in the box vibrates to assist filtration.

An apparatus includes a first fines pan side traversing from a feed end to a discharge end, a second fines pan side traversing from the feed end to the discharge end opposite the first fines side, a first surface traversing from the first fines pan side upwards towards an apex of the fines pan, and a second surface traversing from the second fines pan side upwards towards the apex of the fines pan, the first fines pan side, the second fines pan side, the first surface, and the second surface forming a fines pan. The first fines side having a first fines opening proximate the discharge end. The second fines side having a second fines opening proximate the discharge end.
