Wash water enters the wetting cone and creates a vortex which prevents dry solids from accumulating on the cone walls and organizes solids for optimum flow. Meanwhile, the main liquid stream enters the eductor through a converging nozzle to create a high-velocity jet. Liquid leaving the converging nozzle expands in the discharge horn, generating a vacuum behind it. This vacuum draws the material from the wetting cone through the solids inlet and into the eductor. There, both the motive liquid and the solid from the wetting cone mix to form a slurry. The eductor discharges the slurry to downstream holding or mixing tanks where other ingredients may be added, mixed completely and/or simply stored for further use.
