the aggregate is tumbled through the exhaust gases, the material is heated and dried. Moisture is removed and carried out of the dryer as part of the exhaust gas stream. The hot, dry aggregate is then discharged from the dryer at the lower end. The hot aggregate is usually transported to the top of the plant mixing tower by a bucket elevator.

The cost of aggregate is not, in itself, a major factor in most applications, but its impact on the use of more expensive components, such as cement in concrete or bitumen in asphalt, is quite essential. For that reason, it is important to understand those factors in aggregate processing that have the greatest impact on quality and costs.
