7 Steps in the Aggregate Manufacturing Process
Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and …

The Important Role of Aggregate in Construction
In cement, aggregate occupies the majority of volume in concrete. When you mix in aggregates, it is what pastes together the cement. It is also what changes the look and feel of the surface. The aesthetic of aggregates affects the concretes' countertop. Moreover, the size and gradation of aggregate are important.

How Aggregates Are Extracted | Construction Materials
Sand and gravel quarries are pumped to allow them to be worked dry or operated as lakes with extraction below water. A conveyor draws raw material into the processing plant, where it is washed to remove unwanted clay and to separate sand. Sand separated during processing is dewatered and stockpiled. Gravel then passes over a series of screens ...
