AGGREGATE PRODUCTION This chapter discusses the total process of aggregate production from extraction through processing. Also discussed is the handling, stockpiling, and shipping of the product up to the point where the material leaves the Producer's control. Processing
The first stage of aggregate processing involves quarrying where a large deposit of desirable aggregate is identified and extracted from the ground. Hardened substances are either blasted or cut into smaller manageable-sized rubble and transported by truck or conveyor belts to the processing area.
Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel.

Construction aggregate Wikipedia. Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates..
Stone quarrying is the multistage process by which rock is extracted from the ground and crushed to produce aggregate, which is then screened into the sizes required for immediate use, or for further processing, such as coating with bitumen to make bituminous macadam (bitmac) or asphalt.
optical image processing systems have as of yet not been widely accepted in the aggregate stone industry. Shape distributions are also becoming increasingly important in the performance of rigid and flexible pavements. Shape measurements today, if done at all, are laborious and tedious manual measurements [5].

Our Aggregates Aggregates refer to fragments of rock, sand, and gravel. They are obtained through surface mining, or quarrying, where large rock formations are drilled, blasted, and processed into smaller rocks and sand. Aggregates are an essential component in a wide range of concrete applications, and Lafarge South Africa offers a wide range of them to meet your construction
BoDean Company operates two quarries, BoDean Forestville Quarry and the Mark West Quarry. Once the mountainside is drilled and blasted, quarry stone is then processed into aggregate stone through a step by step process before taking on its desired state and being made into all of the products offered by BoDean Company.
Once processed, the aggregates are handled and stored to minimize segregation and degradation and prevent contamination. Aggregates strongly influence concrete's freshly mixed and hardened properties, mixture proportions, and economy. Consequently, selection of aggregates is an important process.
