ABSTRACT:
A slurry dividing apparatus is configured to divide a main slurry stream into smaller constituent slurry streams, wherein each stream contains a desired proportion of suspended solids. The dividing apparatus includes a main flow channel and a plurality of branch flow channels extending upward from a flow divider that terminates an upper end of the main flow channel. The main slurry stream enters the main flow channel, at an inlet opening thereof, and is decelerated, by an upward extension and expanding cross-section of the main flow channel, before reaching the flow divider and being divided into the smaller constituent slurry streams flowing within the plurality of branch flow channels. Each of the smaller streams flows up and then over a weir, which extends across an upper portion of each of the branch flow channels, and then down into a corresponding discharge flow channel of the apparatus.
