The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry, this stage involves drilling to make holes and develop access to the rock.

Natural aggregate: Weathering and erosion of rocks produce particles of stone, gravel, sand, silt, and clay. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Some natural aggregate deposits of gravel and sand can be readily used in concrete with minimal processing.

Aggregate Processing. At the processing plant, quarried rock undergoes primary and secondary crushing to create the desired end product. The actual method used for processing is based on the type of rock, product requirements and end use. Some aggregates will be crushed to a powder, while others are screened to various diameters.

Polished Stone Value ... Image processing of aggregate morphology: (a) original aggregates; (b) identified aggregates; (c) binarized aggregates. The roundness, widely used as a measure of shape was calculated based on the aggregate feature parameters, as presented in equation (1).

Nevertheless, the process is relatively simple: locate or create (minimal) breaks in the stone, remove the stone using heavy machinery, secure the stone on a vehicle for transport, and move the material to storage. A flow diagram of typical quarrying operations is shown in Figure 1. Figure 1. Process flow diagram for limestone quarrying operations.

Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From …
