A mixing apparatus includes a tub, an agitator disposed in the tub, a flow mixer which provides an initial mixture into the tub, and recirculating means for recirculating mixture from the tub through the flow mixer. In a particular embodiment, the flow mixer has a vertical sleeve through which a dry substance is received for mixing with a liquid input through an inlet manifold through which the sleeve extends. The flow mixer also includes a valve comprising an orifice plate, a valve plate and a body in which grooves are formed for forming jets of liquid to engage the dry substance in a downwardly spiraling circulation. Connected to the flow mixer below the valve are at least two recirculation inputs below which a diffuser is adjustably connected.
