Crushed stone or aggregate can be any type of rock mechanically broken into smaller fragments. Crushed stone is an essential component for today's construction.
Each stage of crushing produces progressively smaller sized stones. In order to produce a usable end-product, the crushed rock has to be screened into various size categories. Crushed and screened rock is called aggregate. Screening is carried out at various stages in the crushing process. Screens are basically box.
Production of these products requires blasting and excavating the broken stone from quarries followed by progressive stages of crushing, screening, washing and blending. Our aggregate products range in size from Rip-Rap, where each stone may weigh several tons, to manufactured sand for use in concrete and asphalt.
Construction Aggregates. Vulcan is North America's leading producer of construction aggregates, primarily crushed stone, sand and gravel. We produce these materials from natural deposits such as granite, line and trap rock. Our quarrying process typically begins with drilling and blasting the rock into smaller pieces.
