Aggregate Screening Equipment

Highly efficient inclined and horizontal vibrating screens that provide high output capacities and accurate separation for screening in mining, sand, gravel, aggregate, recycling and demolition applications.

What is aggregate screening

Aggregate screening equipment is used to classify and sort rock, stone, sand, construction rubble and other materials by size to produce finished aggregate products that meet specification requirements for use in construction materials like base gravel, concrete and asphalt. 

Material is fed onto a vibrating screen box that contains 1 to 4 carry decks with different sizes of screen media (mesh) attached. As the feed material travels across the screen, it falls through the screen openings onto conveyors for stockpiling or further processing.

The screening process is arguably the most important process in aggregate production. Unlike crushers that crush rock and produce material, screens only size material that has been reduced in size by the crusher. The crusher produces the gradation, but the screen produces the specification. Until the crushed material is successfully screened, no money is made.

While all screens are developed to sort and classify material by size, some are application-specific and designed to perform a specific range of duties like scalping, washing, and dewatering. The type of screen required depends on the application and material required.

Scalping Screens

Grizzly Bars and Grizzly Feeders are the most common types of screens used for primary scalping. They are used to pre-screen (scalp) and remove over or undersized rock and other undesirable material that could cause damage or affect the overall performance of the crusher.
Optimizing crusher performance at this stage also improves liner wear and reduces downtime.

Wash Screens

Washing screens, also known as wet screens, are used to remove unwanted materials like silt, rock dust, and organic material from rock, stone, and sand to produce material that meets construction specifications.

Dewatering Screens

Dewatering screens have a wide range of uses, including removing water and slime and scrubbing washed sand, rock and stone. They produce a drip-free product that is immediately usable or salable.
