What is aggregate screening?
The screening process is arguably the most important process in aggregate production.
Screens are used throughout the aggregate, mining and recycling industries to classify and sort rock, stone, sand, construction rubble and other materials by size.
Crushers break rock and produce the gradation. But it’s the screens function to separate, size and sort the crushed material so it can be used in construction materials like road base, concrete and asphalt products.
The crusher produces the gradation, but the screen produces the specification. Until the crushed material is successfully screened, no money is made.
Are you looking for a fast, reliable way to screen rock, stone, sand, gravel and crushed concrete?
