Aggregate, Sand, Gravel Plant
Fine aggregate refers to the gravel or crushed stone material whose stone size is less than 5MM used for preparing the concrete. Fine aggregate is also divided into coarse sand, medium sand, fine sand and finer sand, whose fineness modulus is of 3.7 ~ 3.1, 3.0 ~ 2.3, 2.2 ~ 1. 6 and 1.5 ~ 0.7. According to production sources and materials, fine aggregate can be divided into ordinary river sand, mountain sand, sea sand, artificial crushed sand (stone chips), and waste sand.
Aggregate, Sand, Gravel
Quarrying and production of construction aggregate, sand and gravel for use in highways, roads and streets and other public works projects; construction of housing, nonresidential buildings, commercial and industrial facilities, asphalt and asphalt coatings, cement and ready-mix concrete, as railroad ballast, in non-construction uses including agricultural and various industrial applications, recycled materials, and inert materials acceptance.
There are total about 74,500,000t aggregates used in USA in 2007. Among all, 29,700,000t is from sand and gravel, other 43,900,000t comes from crushed stone. From above, we can see that the crushed stone is one of the important sources of aggregate. SBM is a professional manufacturer of crushing equipment and crushing plant. Our products can be used to crush stones and produce aggregate.
Aggregate Sand, Gravel Plant
Aggregate, sand or gravel crusher major means jaw crusher, impact crusher, in some aggregate crushing plant, cone crusher and VSI crusher is needed.
Jaw crusher is the major crushing equipment in aggregate plant. Jaw crusher play roles as primary crushing to break large raw rocks, stones into small particles.
Impact crusher is an important crushing equipment in aggregate plantto produce high quality aggregate. The major feature of impact crusheris that the final produce of impact crusher is in cubical shape, whichis suitable to be used as high quality aggregate.
VSI (vertical shaft impact) crusher is a high performance crushingequipment for aggregate production. VSI crusher has two workingmethods: 'rock on rock' and 'rock on iron'. Sand aggregate yield of 'rock-on-iron' type is higher by 10-20% than that of 'rock-on-rock' type. VSI crusher is widely used to crusher hard rocks like basalt,granite, hard limestone etc.
The capacity of aggregate crushing and screening plant is from 30 to 1000TPH. The layout of aggregate crushing and screening plant incudes PE jaw crusher, PFW impact crusher, HP cone crusher, VSI crusher.
The technology of three crushing stages, with jaw, cone, impactor,VSI crushers, makes it possible to produce cubical-shaped aggregate(Aggregate and gravel from compact rocks for civil constructionspecifications) in fractions of 40-70 mm, 20-40 mm, 5-20 mm (roundholes) and manufactured sand in a 0-5 mm fraction. The flexibletechnology facilitates adaptation of production to market requirementsand an output of narrow fractions and aggregate for railway ballast.
