To process 300 tons per hour of sand and gravel, a company will use 1,00 to 2,000 gallons of water. In the past, the dirty washwater was trans ferred into a system of three to four ponds, where the silt and mud would settle out over time, with some clean water eventually being reused in the screening process. A case in point is Johnson Sand Gravel Company, New Berlin, Wiscon sin. The plant ...

The homogeneous sand filter has a –1 m deep bed and typically of – mm of sand (effective size mm) placed on a 50 mm layer of 4–8 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.

Introduction. Sand and gravel are used extensively in construction. In the preparation of concrete, for each tonne of cement, the building industry needs about six to seven times more tonnes of sand and gravel (USGS, 2013b). Thus, the world's use of aggregates for concrete can be estimated at billion to billion tonnes a year for 2012 alone.
