ABSTRACT:
This invention relates to an improved aggregate drying apparatus and method where the dried aggregate is particularly useful for making hot mix asphalt. In accordance with the system, heat typically lost in exhaust gases and moisture evaporated in a heater is recovered to dry and preheat the aggregate. The invention also relates to novel components used in the system, including an improved aggregate dryer and an improved mass flow apparatus for use in an aggregate dryer or otherwise in aggregate feed bins.
