The purpose of the aggregate processing plant is to prepare the rock or mineral in a form suitable for its use as aggregate, commonly defined in terms of particle size and size distribution, particle shape and mechanical properties, e.g. …
Construction Aggregates 101: What They Are (and Why …
Aggregates are raw materials that are produced from natural sources and extracted from pits and quarries, including gravel, crushed stone, and sand. When used with a binding medium, like water, cement, and asphalt, they are used to form compound materials, such as asphalt concrete and Portland cement concrete.
How Aggregates Are Extracted
Ever wonder where gravel comes from? Watch our video to learn how rock and other aggregates are removed from quarries (and marine environments).

Aggregate – Pavement Interactive
Aggregate Production. Aggregates are produced in a quarry or mine (Figure 1) whose basic function is to convert in situ rock into aggregate with specified characteristics. Usually the rock is blasted or dug from the quarry walls then reduced in size using a series of screens and crushers.

7 Steps in the Aggregate Manufacturing Process
What Is the Aggregate Manufacturing Process? The aggregate production process mainly concludes 7 steps. Mining Process. First, we need to mine the raw materials that can be made into aggregates. The methods required for mining include blasting operations, drilling operations, manual digging pile operations and dewatering operations.
Construction aggregates: evaluation and specification
The shape of aggregate particles is a product of the rock type, depositional environment and quarrying and production process. For example, hard, tough or brittle rocks will often generate more flakes, whereas softer rocks produce more fines.
