<p>A controlled rate feeder system for fine particle solids and a method thereof includes a plate assembly housing, a seat plate assembly, a backseat plate assembly, at least one biasing device, and an actuator assembly. The plate assembly housing has an inlet and an outlet which are connected together by at least one passage. The seat plate assembly is moveable to any position between covering and exposing the inlet. The backseat plate assembly is positioned adjacent to and moveable with the seat plate. At least one biasing device is positioned between the seat plate assembly and the backseat plate assembly which biases the seat plate assembly and the backseat assembly apart. The biasing device also biases the seat plate assembly against an inner surface of the plate assembly housing and the backseat plate assembly against another inner surface of the plate assembly housing. The actuator assembly moves the seat plate assembly between the position covering the inlet and the position exposing the inlet.</p> |
