The dispenser has a container adapted to be mounted upon a rotatable shaft and having a hollow interior with two openings therethrough for communicating with external surroundings. A partition is mounted within the container interior for dividing a portion of the container interior into a plurality of compartments. The partition extends between the openings to limit quantity of matter falling into one of the compartments as the container rotates. A duct is mounted to rotate with the container and communicates with one of these openings. As the container rotates, the partition regulates the quantity of matter falling into the dispensing compartment and directs matter not discharged from the dispensing compartment back into the other compartment.
