11.19.1 Sand And Gravel Processing

some deposits, blasting is required to loosen the material prior to processing. The material may undergo primary crushing at the mine site before being transported to the processing plant. Figure 11.19.1-2 is a flow diagram for industrial sand and gravel processing. The mined rock is transported to the processing site and stockpiled.

Aggregate Concrete - an overview ScienceDirect Topics

The technology of aggregate processing is complicated and continually developing and is more comprehensively covered elsewhere. 25,26,40,41 In general terms, however, processing consists of a reduction stage (always with crushed rock and sometimes with sand a gravel), a washing and beneficiation stage (as required) and a sizing stage.

Aggregates - Portland Cement Association

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
