An apparatus configured for connection to a mixer for receiving a slurry and altering the flow characteristics of the slurry includes a conduit having a main inlet in slurry receiving communication with the mixer outlet and extending to a spout for discharging the slurry, at least one conduit restrictor associated with the conduit for creating back-pressure between the conduit restrictor and the mixer outlet for keeping the mixer full, and at least one pressure reducer associated with the discharge spout and configured for reducing the pressure of the slurry dispensed from the discharge spout. The apparatus is configured for maintaining a generally laminar flow from the mixer outlet to the discharge spout.
