aggregates—sand, gravel, crushed stone, and aircooled blastfurnace slag—produce freshly mixed normalweight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 53) are used to produce structural lightweight concrete with a freshly mixed density
AGGREGATES Aggregates (or mineral aggregates) are hard, inert materials such as sand, gravel, crushed stone, slag, or rock dust. Properly selected and graded aggregates are mixed with the cementing medium asphalt to form pavements. Aggregates are the principal loadsupporting components of an Asphalt Concrete pavement.
In the wet processing of construction aggregates, scrubbing is the action of removing clays, vegetation and other unwanted, sometimes sticky coatings. When it discharges, a scrubbed material transforms into a higher grade, highervalue product.
The principal design parameters that drive crushing plant selection and configuration include: • Production requirements • Capital cost ... Example: 60" x 89" primary crusher mill feed conveyor system Operating schedule calculation for 3 x 8 hours per shift Days per year 365 Tonnes per year 32,850,000
The sixdigit Source Classification Code (SCC) for construction sand and gravel processing is 305025, and the sixdigit SCC for industrial sand and gravel is 305027. Construction Sand And Gravel Sand and gravel typically are mined in a moist or wet condition by open pit excavation or by dredging.

Syntron Material Handling Engineering Manager Brad Nichols recommends a rear wall angle of 60° ± 2°. 2. The hopper front wall angle must be just big enough to permit material flow. The flow rate on the hopper front wall should be slightly less than the flow rate on the back wall. Nichols recommends a front wall angle of 55° ± 2°.
The coarser fraction is pumped to the Spiral Classifier, which receives the 3/8″ x 1/8″ product and is the finer constituent of this product. The overflow from the hydraulic classifier is discharged to a SRL Pump and Cyclone. The underflow from the cyclone joins the finer fraction from the hydraulic classifier to produce the 1/8″ x 0 sand ...

The homogeneous sand filter has a m deep bed and typically of mm of sand (effective size mm) placed on a 50 mm layer of 48 mm or 75 mm of mm gravel. Homogeneous sand of effective size up to mm has also been used. The stated size ranges for sand and gravel are generally 5 and 95 percentiles.
Construction aggregates are produced from naturally occurring mineral deposits, including solid rock formations such as limestone and granite, and from loose deposits of sand and gravel. The most common structural uses of construction aggregates include the coarse and fine mineral components in Portland cement concrete and asphalt.
