Types of asphalt production plants

All types of asphalt production plants consist of five distinct parts the cold aggregate feeder system, the dryer/heater, the dust collection system, the mixing system and the storage bins. The mixing system is basically the factor that determines their categorisation. 

In batch plants, the hot aggregates are stored in hot bins before mixing with bitumen in discrete batches in a pugmill (typically) mixer and then loaded onto trucks or transferred to a silo (or silos) for temporary storage. 

In drum-mix plants, the mixing of the aggregate and the bitumen takes place in the dryer/ heater drum, after which the asphalt is stored in a silo (or silos) before being loaded into delivery trucks. 

Each of the above two categories split into two sub-categories. The first category splits into
