The process flow of any asphalt plant will depend on the type of plant. Right now we have different types of asphalt mixers available in the market. These mixers are build keeping in mind different customer types. There are two major types Of categories batch type and continuous type: Batch type: With this design, the production of the hot mix will be done in batches of specific sizes.

Figure 3, a flow diagram for hot-mix batch asphalt plant, shows (3 equipment and sources of emissions for this process. The equip- ment usually consists of: 1. A rotary drier for removing moisture from the sand and crushed stone.

The environment is carefully considered throughout the asphalt manufacturing process . Emissions from oil refinery plants and asphalt manufacturers are rigorously controlled using equipment that re-collects the dust and particulates and re-uses them in the heating process. This saves them from being emitted into the environment and also ...
