Construction aggregate is typically medium or coarse material that is used in construction applications. These materials may consist of crushed stones like granite, limestone or trap rock, sand, gravel, slag or recycled concrete. These aggregates can be used in a variety of applications from road or sidewalk base products to railroads and airports and commercial buildings like hospitals, schools and even homes. Before using these products, they need to be processed to fit the appropriate specifications. Processing the material may include reducing its size with a crusher, sizing the crushed material with a screen and conveying the material into different stockpiles.
