    • A screw type centrifugal liquid separation machine having a continuous decanter and using pressurized air to promote solids transport is provided. The machine has an outer bowl and a conveyor, which are coaxial. A back drive assembly is provided to maintain a difference in speed between the bowl and conveyor so that the conveyor has a mechanical sweeping action within a separation region of the machine. Air is introduced into the machine through the back drive assembly, and is injected into the heavy phase discharge path. In one location, the air acts as a turbulence inducer that at least partially re-suspends grits within the heavy phase material. The air is also injected through lift injectors radially spaced about the solids baffle to provide a uniform solid phase driving force. A flow control is also provided for controlling the discharge rate of the heavy phase material through a discharge port.
