Abstract

The hopper tee provides increased material flow rates and includes a first hollow pipe section having an upper end and an opposite lower end, the upper end including an inlet opening for connecting to a discharge opening of a hopper for receiving material contained in the hopper therethrough, and an interior cylindrical side wall forming an internal passage connecting the inlet opening to the lower end for flow of the material thereto. The hopper tee includes a second hollow pipe section having a first open end, an opposite second open end, an intermediate portion therebetween, and an interior cylindrical side wall forming an internal passage connecting the first and second open ends providing a flow path for a flow of air therethrough, the lower end of the first hollow pipe section being connected to the intermediate portion of the second hollow pipe section forming a material inlet port connecting the internal passage of the first hollow pipe section to the internal passage of the second hollow pipe section for flow of the material into the flow path. The hopper tee further includes an element or flow director disposed in the internal passage of the second hollow pipe section hav…
