Crushed aggregate, also known as rock aggregate, refers to a crushed stone product produced in quarries. In areas where natural sand and gravel aggregate deposits are insufficient to handle local demand, larger stones are processed in an impact crusher to create crushed rock aggregate. The greater costs of production involved in mining and processing the stones to create crushed aggregate mean

Crushed Stone Grade 1-10. Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing

Crushed Stone Production Graph: Crushed stone production trends for the last 100 years. Data from USGS [1]. Crushed stone production has generally been rising, with most of the drops caused by major or minor economic recessions. The dramatic rise began shortly after the Second World War when effective track equipment was developed.
