Crushers break down large rocks into smaller pieces to such as sand, gravel, or slag to be used in aggregate via pressure or striking. Typically, rocks will go through multiple rounds of crushing to reach the desired size. Crushers are also used in construction material recycling and mining operations.

Nomenclature and Terminology. James G. Speight PhD, DSC, in Asphalt Materials Science and Technology, 2016 1.5.1.6 Slag. Slag aggregates are obtained by crushing of smelter slag or by special treatment of fire-liquid slag melt (molten slag aggregates). Currently there are many types of concrete that are developed and used in construction that …
Artificial aggregates, such as fly ash lightweight aggregates, can be used as eco-friendly alternatives to natural aggregates. This work aims to investigate the effect of curing time on the hydration and material properties (voids, shrinkage, crushing strength and pH) of cold-bonded high-calcium fly ash–Portland cement lightweight aggregate. …
The study investigates the use of artificial aggregates (AAs), specifically manufactured from ground granulated blast furnace slag (GGBFS) and ordinary Portland cement (OPC), to mitigate environmental harm caused by illegal quarrying due to the scarcity of natural aggregates (NAs).
