The importance of aggregate processing
Construction materials are in all roads, bridges, footpaths, and buildings. Not everyone considers what construction materials are, where they came from, or how they’ve been processed. The majority of our built environment is formed from raw materials sourced from the Earth by the extractive industries. Rock, sand, and gravel has to be crushed and screened into various size categories in order to produce a usable product.
Powerscreen’s full range of mobile crushers, screens, and conveyors are designed to take raw materials and reduce them to sorted usable aggregates sizes. The versatility of having a fully mobile machine allows the customer to efficiently process
raw materials on site into finished aggregate. By streamlining the amount of raw material movement and reducing transportation, operating costs are kept to a minimum. Responsibly processing raw materials can reduce our carbon footprint while allowing
us to build houses, schools, hospitals, factories, and roads.
