Abstract: A screening disk for use on a roller of a roller screen for screening an ore feed is disclosed, which includes first and second opposing side working surfaces, and provisions for mounting the screening disk on a shaft of the roller. At least one of the first and second side working surfaces has a plurality of protrusions operable to extend outwardly into an interstice between the applicable side working surface and a side working surface of an adjacent mounted screening disk. A spacer may be disposed in the one interstice for confining an extent of the one interstice to a region disposed generally between the third working surface and the shaft. A screening disk may have a keyway configured to receive a key for coupling the body of the screening disk to the shaft for rotation therewith.

Abstract: A sizing roller screen apparatus and method for processing an ore feed that includes sized and oversize ore portions and is received at an inlet are disclosed. The apparatus includes a roller screen having a plurality of adjacent screening rollers with interstices therebetween for permitting passage of the sized ore portions, the adjacent screening rollers being rotatable to cause a first sized ore portion to pass through the interstices as while the ore feed is transported along the roller screen. The apparatus also includes a sizing roller disposed generally above an opposing one of the adjacent screening rollers, the sizing roller being rotatable to fragment at least some of the oversize ore portions passing between the sizing roller and the opposing screening roller to produce a second sized ore portion, the second sized ore portion being sized for passage between the interstices.

The apparatus includes a roller screen having a plurality of adjacent screening rollers supported to provide interstices therebetween for permitting passage of the sized ore portions between the adjacent screening rollers, the adjacent screening rollers being operably configured to rotate to cause a first sized ore portion to pass through the interstices while the ore feed is being transported along the roller screen. The apparatus also includes a sizing roller disposed generally above an opposing one of the plurality of adjacent screening rollers, the sizing roller being operably configured to rotate to fragment at least some of the oversize ore portions passing between the sizing roller and the opposing screening roller to produce a second sized ore portion, the second sized ore portion being sized for passage between the interstices.

Abstract: A system and method for transporting a slurry apparatus to a new operating location is disclosed. The system includes a first mobile support for coupling to a first lifting region of the slurry apparatus, the first mobile support being located adjacent to the slurry apparatus. The system also includes a second mobile support for supporting a second lifting region of the slurry apparatus, the first and second lifting regions being selected such that a center of mass of the slurry apparatus is disposed within a stability region defined between the first lifting region and the second lifting region. The first and second mobile supports are operable to take up a load of the slurry apparatus and to advance in a desired direction to cause the slurry apparatus to be moved toward the new operating location.
