Moving Materials Through Asphalt Plant Processes
There are three standard conveyor belt functions in an asphalt plant: Feeder Conveyors, Collecting Conveyors, and Charging Conveyors.
Feeder conveyors control the flow of aggregate between the feed bin system and the collector conveyor in the overall system. They use variable speed belts to help control the amount or proportion of each kind of aggregate.
The collecting conveyor catches the various proportions of aggregate from the individual feeder conveyors and moves it at a constant speed through the scalping screen (if one is used) to the charging conveyor.
Finally, the charging conveyor moves the combined aggregate mixture to the mixing drum. It moves at a constant speed but accommodates varying amounts of the aggregate mixture depending on the volume coming from the set of cold feed bins and RAP bins.
