ABSTRACT:
Bulk material discharge assemblies comprise a bulk material hopper, a conduit for delivering an air stream to entrain with bulk material from the bulk material hopper, and a feeding apparatus for introducing additive to the conduit. 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. The first and second metering wheel are adapted to be selectively mounted in at least one of a first relative position and a second relative position. Still further, apparatus for dispensing additive are provided that comprise an additive hopper including at least one partition for dividing the additive hopper into at least two containment areas that are substantially isolated from one another and a metering device mounted to the additive hopper.
