Improved Apparatus for the Reclamation of Slurry from the Bottom of a Storage Silo Abstract This is an improved apparatus used with a storage and reclamation apparatus which handles slurry formed of particulate matter and fluid. The reclaim apparatus in- cludes a tank having a side wall and bottom. The slurry is added into the tank and is subsequently removed from the tank by a downwardly facing bell mouth coupled through a pipe to a pump. Fluidizing jets surround the bell mouth with a dilution control port mounted between the mouth and the pump. The dilution control port is connected to a second pump in series with a source of fluids. Process control apparatus measures the flow and density of the material being drawn into the mouth and adds or reduces dilution fluid in accordance with a set point so that a constant density is maintained at all times. The improved version accepts the overflow from the tank into a second tank which has a second bell mouth mounted at the bottom of the tank. Solids and fluids are sucked into the second bell mouth and used as the source of fluid for the dilution port of the first tank.
