Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
· The crushed aggregate is divided into high-quality recycled aggregate of 5-20 mm by secondary screening, which can be used in the concrete manufacturing of C25-C30. The high-quality recycled fine aggregate of 0.15 mm-5 mm and the fine powder of 0.15 mm or less are selected by tertiary screening. Common aggregate production line configuration
The Spyder 622TH Triple Deck Screen is a track-mounted aggregate screening plant featuring a 6′-0″ x 22′-0″ (1.83m x 6.7m) horizontal shaker screen. View our Spyder 622TH Triple Deck Rock Screen
· Also, screening is impractical for aggregate smaller than No. 8 mesh, in which case, hydraulic separation, or classifying, becomes an important operation. Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh).

produce crushed aggregate, or to produce manufactured sands. Crushing generally is carried out in one or two stages, although three-stage crushing may also be performed. Following crushing, the material is returned to the screening operation for sizing. The material that passes through the scalping screen is fed into a battery of sizing screens,
