Continuous mix plant; The purpose served by both the plants is the same. The difference lies in the method by which they produce asphalt. Asphalt batch mix plant operation: The operation of asphalt batch mix plant starts from feeding the aggregates into the feeder bins. The operation ends when hot mix asphalt is discharged into the truck.
There are several types of Asphalt Mixing Units for example batch plants parallel-flow drum plants counterflow drum plants double barrel drum plants and continuous mix plants and so on. When all is said in done the greater part of plants can be grouped into either a drum mix plant or a batch plant.
The three types of plants differ however in operation and flow of materials as described in the following sections. BATCH PLANTS . The major components of a batch plant are the cold-feed system asphalt cement supply system aggregate dryer mixing tower and emission-control system. A typical batch plant is depicted in Figure 5-1; the major
asphalt plants in the United States. Of these 3600 plants approximately 2300 are batch plants 1000 are parallel flow drum mix plants and 300 are counterflow drum mix plants. The total 1996 HMA production from batch and drum mix plants is estimated at about 240 million tons and 260 million tons respectively. About 85 percent of plants

HOT MIX ASPHALT PLANT OPERATIONS An asphalt mixture plant is an assembly of mechanical and electronic equipment where aggregates recycled materials or other additives are blended heated dried and mixed with binder to produce asphalt mixture meeting specified requirements.
