Abstract
A slurry apparatus for creating a slurry from oil sand ore has a frame and a slurry box supported by the frame. Water is mixed with the ore to form a slurry that is retained in the slurry box. The slurry apparatus may include a screen disposed at an angle relative to the horizontal over an open top of the slurry box and configured to permit sized ore to fall through the screen into the slurry box. The apparatus may include at least one crushing device cooperating with the screen to facilitate creating the slurry. A related method and system for creating a slurry may also be provided.
Claims4
A slurry apparatus for creating a slurry from oil sand ore, comprising a frame, a slurry box supported by the frame, a water supply in communication with the ore or the slurry box, whereby water is mixed with the ore to form a slurry that is retained in the slurry box, at least one sloped screen disposed at an angle relative to the horizontal over an open top of the slurry box, a primary crusher disposed above an upstream end of the sloped screen, and a secondary crusher disposed beneath a downstream end of the sloped screen, whereby the primary crusher sizes the ore and deposits the ore on the sloped screen so that sized ore falls through the screen into the slurry box, and the secondary crusher crushes oversized ore that falls off the downstream end of the sloped screen for deposit into the slurry box.
