ABSTRACT:
A dispenser to dispense a granular material to a plurality of discrete locations, such as a tube of a reactor vessel. The dispenser includes a hopper to contain the granular material and has a discharge port to permit egress of material from the hopper. A conveyor receives material from the discharge port and transfers it to the plurality of discrete locations. The conveyor comprises a tray having a plurality of outlets spaced from the discharge port and each connectable to respective ones of the discrete locations. A barrier is interposed between adjacent ones of the outlets to inhibit transfer of material therebetween. A vibratory drive oscillates the tray and distributes the granular material uniformly on the tray. The drive induces movement of the material from the discharge port to the outlets along the tray.
