An improved particulate metering system is provided. The system includes a flow path having an inlet in communication with an intake and an outlet in communication with a discharge. The flow path receives a first input and a plurality of inputs, each of the plurality of inputs having a separate origin. A mixing area within the flow path comprises a confluence of the first input and one or more of the plurality of inputs. One or more metering controls are in operable communication with the first input and the plurality of inputs for controlling a blend of the plurality of inputs at the confluence.

A hopper tee having a horizontal portion through which granular material is unloaded from a tank trailer or hopper car, the hopper tee integrally forms a vertical segment, that secures with the bottom of the hopper, to provide for unloading of granular material for usage or storage. The upper front portion of the tee, as it transitions from its vertical segment to the horizontal flow path has secured or cast therewith a ledge, that provides for accumulation of the unloading granular material therein, to function as a wear pad to resist against abrasion and accelerated wear out of the tee, at that location, during prolonged usage.
