Aggregate Concrete - an overview | ScienceDirect .

The objective of any concrete aggregate processing operation should be the production of good-quality, 'clean' coarse and fine materials in the normal range of sizes. The types of equipment used and the flow design of the plant are more or less completely dependent upon the nature and properties of the source raw material. Even after basic design, any plant will require commissioning ...
