Drying drum is the horizontal cylinder in an asphalt mixing plant that uses burner heat to dry thecold aggregate and other ingredients. The process involves tumbling damp materials on one sideof the rotating drum. The aggregate temperature control also determines the asphalt mixtemperature. Hence, it’s an essential component of the mixing plant.
Coal Burner
The coal burner contains a coal pulverizing machine, host combustion machine, a rotationsystem, carter and ignition system. The coal is crushed and then transported to the burningchamber.
Aggregate Supply System
The aggregate supply system works with a feeding belt that transports the aggregate and a lightalarm system which notifies the workers in case there is something off the confiquration – belowlimit carrying capacity or material lack.
Dust Collector
The dust collector is used with a dryer where it collects the dust released by dryer’s exhaust. Thedust is either wasted or reused with the aggregate.
Screening Unit
The screening unit is located on top of the plant bins where the dried aggregate is deployed. ltneeds to be large enough to accommodate the aggregate. Oversized aggregates are rejected bythe screening unit.
