ABSTRACT:
An apparatus is described for transporting particulate material. A housing includes a wall defining an inlet and a wall defining an outlet spaced downstream from the outlet. A duct is enclosed in the housing between the inlet and outlet, the duct being formed between first and second substantially opposed drive walls moveable relative to the housing from the inlet toward the outlet and at least one arcuate wall extending between the inlet and the outlet. The drive walls have a greater surface area for contacting the solid material than the arcuate walls. The drive walls rotate relative to an axis. An assembly is provided for positioning the second drive wall in the housing for rotation in a plane at an angle relative to the axis such that the distance between the first and second drive walls adjacent the inlet is greater than the distance downstream from the inlet when the drive walls are moving.
