Emission Control System

As hot air passes through the aggregate it picks up some fine sand and dust particles. These particles are removed by the emissions control system before the air goes into the atmosphere. Most plants have primary and secondary collectors to remove these particles. The fine sand and some dust is collected in the primary collector and returned to the mix. The secondary collector removes the remaining fine dust. In most cases this dust can also be returned to the mix.
