Aggregates are the most commonly used construction minerals in the UK and are essential for the sustainable development of a modern economy. The resources of material suitable for use as primary aggregates in England comprise land-won and marine sand and gravel, and crushed rock (limestone, sandstone, igneous and metamorphic rock).

Aggregate production operations are defined in Water Code ch. 28A as sites from which aggregates are or have been removed or extracted from the earth, such as quarries and gravel pits. Outside of statute, aggregate processing operations are those that process aggregate materials for use, such as rock crushing facilities. Often,

Aggregate manufacturing typically starts by blasting rock masses and is followed by a series of crushing stages. Comminution in typical hard rock quarries is sketched in Fig. 1. ASTM particle size distributions of select aggregate products are also shown in Fig. 1 . Crushing operations can accommodate some adjustment to match the demand for

Crushed gravel is an aggregate frequently used in construction. The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry and then transported to the rock crusher, which begins the process of crushing the larger stones into more manageable pieces.
