摘要：A rotary feeder has a valvular rotor rotating on an axis in a cylindrical cavity. Aplurality of rigid, free-floating blades project from a hub of the rotor to delimit severalmaterial-receiving pockets circumferentially distributed over the hub. The inner edges ofthe blades rest in axial recesses in the hub and are supported by fixed projectionsextending outwardly from the hub along the trailing side of the blades. The recessespermit limited angular movement of the blades relative to the hub. The blades havewidths from the hub to the periphery of the cylindrical cavity greater than correspondingradii through the inner edges of the blades at the hub, whereby the blades are angularlyinclined relative to such radii. Top portions of the blades are applied to peripheral wallportions of the cylindrical cavity. The recesses, the fixed projections, and peripheral wallportions of the cylindrical cavity cooperate to hold the blades in position. The fixedprojections carry means for urging the blades toward the corresponding radii. The bladesare biased or periodically adjusted angularly toward the mentioned corresponding radiiduring wear of the outer portions and the peripheral wall portions to maintain worn topportions of the blades applied to the peripheral wall portions of the cylindrical cavity.
