Section control system

An assembly to move flowable particulate material, the assembly including:

• a conduit to which the material is delivered and to which an airstream is supplied to move the material along the conduit to a delivery downstream destination;
• a separator to engage the airstream to concentrate the material in a concentrated portion of the airstream by separating a separated portion of the airstream, the separator being positioned within the conduit;
• an output connected to the conduit downstream of the separator to receive the flowable particulate material and deliver the material to the downstream destination;
• an air distribution head in constant fluid communication with the separator to receive the separated portion of the air stream and also in constant fluid communication with the output to assist the delivery of the flowable particulate material by the output to the downstream destination by delivering the separated portion of the air stream to the output;
• a control device operatively associated with the output to selectively deliver a pre-determined rate of the material to the downstream destination;
• and
• a mixing conduit located between the separator and the output, the mixing conduit being adapted to guide the concentrated portion of the airstream to the output and including a device to induce turbulence in the concentrated portion of the airstream to accelerate a mixing of the material in the concentrated portion of the airstream,
• wherein the device to induce turbulence includes one or more dimples formed in the mixing conduit.
