An
asphalt mixing plant is a machine used for producing
asphalt, which used to pave the road. The
asphalt is made of bitumen, aggregate and filler, sometimes collectively known as blacktop or
asphalt concrete.
Countries have individual specifications stipulating how much of the raw material can be allowed from recycled
asphalt. In-depth research shows that addition of up to 20% recycled
asphalt produces the same quality of
asphalt compared to 100% virgin material. The quality of
asphalt starts reducing once the percentage of recycled
asphalt increases beyond 20%.
Main Structure
The
asphalt plant is mainly composed of cold aggregate supply system, drum dryer, coal burner, coal feeder, dust collector, hot aggregate elevator, vibrating screen, filler supply system, weighing and
mixing system, Pollution Control Unit ,
asphalt storage, bitumen supply system. All these components have characteristics that impact not only the overall quality of the
asphalt but also the effect on the environment.
