Abstract
An apparatus and a method include a pipe comprising a first end, a second end and an interior wall. The pipe is configured for rotation about an axis with a rotational rate sufficient for a cohesive material to remain stationary in a layer on the interior wall. A plurality of blades is configured for deflecting the cohesive material. Each of the blades includes a blade edge having a curvature corresponding to a portion of the interior wall. A support structure supports the blade edges with each of the blade edges proximate the interior wall and having an angle with respect to a plane perpendicular to the axis. An inlet apparatus feeds the cohesive material into the first end where a difference in rotational rate between the interior wall and the plurality of blades, and the angle determines a rate of conveyance of the cohesive material along the interior wall.
