ABSTRACT:
Mixing equipment includes a mixing compartment and at least one mulling assembly for dispersing therein material, including granular material, such as foundry sand. An agitator is provided for improving the mulling and aerating of the dispersed material within the compartment. The agitator includes a rotor rotated about an upright axis disposed within a cavity opening into the mixing compartment. The rotor includes a hub disposed within the cavity and having a plurality of fingers extending outwardly therefrom. Upon rotation of the rotor, the fingers move forcibly out of the cavity and into the mixing compartment to impact the material moving therepast, for mixing and aerating the material. An overflow discharge opening in a side wall of the compartment permits the prepared material to be discharged continuously from the mixing compartment. The supply of material to the compartment and the discharge of material are under the control of door, material consistency sensing, and timing apparatus. In order to interrupt efficiently the continuous production of prepared material, a controlled shutdown cycle of operation enables the mixing equipment either to resume production, if desired, following an interruption, or to cease production altogether.
