Aggregate and Manufactured Sand Application

Manufactured sand and its application is the leading growth area in aggregate for construction. Historically, manufactured sand has been a by-product of the crushing and screening process. Today, due mainly to environmental constraints, the focus is shifting to the deliberate manufacture of sand to fill demand that natural sand deposits cannot continue to supply. Manufactured sand can be used as product to control the cost or quality of aggregate production.

Aggregate Production Plant Design

Correct process for the production of manufactured sand is key to producing an aggregate of sufficient quality for concrete production. The process used must match the properties of the source rock.

Raw stone quality is important for selection of a crushing circuit. It has been found that the energy input is directly proportional to the strength of the rock. Higher strength rock requires more energy input to create surface area.

A typical aggregate production process flow would engage a VSI, high frequency screen and an air classifier to produce high quality fine aggregate products. The VSI crushers meet the market's need for producing increasing quantities of highly cubical materials, or manufactured sand.
