Aggregates are granular, inert materials, construction aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete, and geo-synthetic aggregates. Aggregates are the most mined material in the world. It usually produces by aggregate crushing plant.
The construction industry is highly prosperous in modern times. More and more aggregate materials are required all over the world. Aggregate is the natural available deposits of sand or gravel. However, natural deposits of aggregate are very limited in the natural world. Most aggregates are obtained from the crushed large rock, gravel, sand or other materials. Aggregate crushing plants are important equipment for aggregate processing. Aggregate commonly is classified into two categories: fine aggregate and coarse aggregate. Fine aggregate is the materials that could pass the No.4 sieve, and most could be retained on a No. 200 sieve. Coarse aggregate is a relatively big materials that will get through a 3-inch screen and be retained on the No.4 screen. Different types of aggregate materials will be used for various applications, they all plays a crucial role in the construction of city infrastructures.
Aggregate crushing operation is the processes of dealing and processing of nonmetallic mineral materials for construction industry. Nonmetallic mineral material will be first quarried or mined and then conveyed to the processing plant for further classification or further size reduction by aggregate crushing plant.
Treatment of aggregates to obtain finished products suitable for each use. The basic stages are:
It allows the particle size to be reduced in successive phases, using crushing equipment of different characteristics, such as jaw crusher, impact crusher, rotary, ball mills or bar mills. In the sands and gravels of alluvial origin, only the large sizes are crushed, therefore, the number of crushing stages is usually lower.
