Disclosed is an apparatus and method for wetting dry particles and dispersing the particles in a liquid. The dry particles are delivered onto a vibrating tray, which has a circular discharge opening therein and a circular plate secured to the tray below the opening. Positioned below the tray is a closed container, which includes a body of liquid and an opening in the container lid for receiving the vibrating plate member. A vertical conduit section in the container has an open end positioned above the liquid surface and directly below the plate member. In a typical operation, a liquid stream under pressure passes upwardly in the vertical conduit and discharges in the form of a circular spout. From the tray the particles fall onto the vibrating plate member, and then downwardly, in a circular curtain pattern, into the liquid spout. In practice, the dry particles will strike the liquid just beyond the apogee of the spout. This enables the particles to move on a downward vector, along with the liquid, so that good wetting and dispersing are achieved. The apparatus has particular utility in wetting and dispersing dry particles which are difficult to solubilize, such as polymeric flocculating agents.

A method for wetting dry particles and dispersing the particles in a liquid, the method comprising the steps of: storing a charge of dry particles in a hopper; delivering the dry particles from the hopper into a feeder tray, the tray having a discharge opening therein and a plate member secured to the tray directly below the discharge opening; positioning the plate member inside a closed container which is located below the feeder tray, the container including a body of liquid; vibrating the feeder tray and plate member to cause the dry particles to drop through the discharge opening and onto the plate member; positioning a vertical conduit section in the closed container directly below the center of the plate member, the conduit section having a deflector member fitted therein; flowing a liquid stream upwardly through the vertical conduit to cause the stream to strike the deflector member; discharging the deflected stream from the vertical conduit in the form of a circular liquid spout which falls into the liquid in the container; dropping the dry particles from the plate member in the form of a circular particle curtain which strikes the liquid spout; wetting the dry particles in the liquid spout and carrying the wetted particles into the liquid in the container; agitating the liquid in the container to thereby disperse the wetted particles into the liquid in the container.
