The function of the hot bins is to provide adequate temporary storage for the separate hot aggregates
before mixing with the asphalt binder in the weigh hopper below them. Narrow hot bin gates
open into the weigh hopper. Quality control samples should be taken at this point from hot bins to
ensure proper functioning. To ensure a smooth flow of materials from the screen decks to the bins
and into the hopper and avoid segregation, it is important that the aggregates are supplied through
the cold feed at a rate that is consistent with the demand for production.
