The feeding apparatus comprises an additive hopper and an airlock positioned adjacent the conduit. In addition, metering apparatus are provided that comprise an axle and first and second metering wheels. A noncircular perimeter of the axle and the shape of each hub opening of each of the metering wheels cooperate to nonrotatably mount each metering wheel to the axle.
