Abstract

A rotary feeder for jam-free operation over a wide speed range has a housing with a feed inlet provided with a roof-shaped baffle plate which, in the running direction of the rotor, includes double-arrowed stripping edges. Each compartment of the rotor includes two radial partitions which extend beneath the baffle plate and are spaced from each other by the width of the baffle plate to define an initially bulk material free space. This space between the partitions of each compartment is connected via circumferential openings with the respectively lateral areas of the rotor compartment to allow granulate particles to enter the space after traveling along the stripping edges.
