Abstract
A separator apparatus to separate less dense particulate material from dense particulate material has a tank for containing fluid which has sidewalls and a sloping bottom with upper and lower ends. A vertically oriented housing is secured to the tank and has an upper and lower end with the lower end being in the tank and the upper end extending above the tank. An auger means is mounted within the housing and extends the substantial length thereof. A discharge location is located in the tank adjacent the lower end of the bottom for removing dense objects therefrom. The housing has a discharge location at its upper end for discharging the less dense objects lifted from the tank by the auger apparatus. A spout is located at the discharge location for the housing and has a spout that has a wall tangential to the cylindrical housing for quickly and easily receiving less dense objects from the outer periphery of the helical flighting.
