Sand soils are often dry nutrient deficient and fast draining They have little or no ability to transport water from deeper layers through capillary transport Therefore tillage of sandy soils in the spring should be kept to a minimum in order to retain moisture in the
Classification is also a sizing process which involves particle size as the primary physical parameter but also is affected by particle specific gravity It is a wet process although dry classification exists and involves a moving fluid medium which transports the particles to separate products based on size and SG accordingly

Density is an important parameter for aggregate For aggregates density is determined by multiplying the relative density specific gravity of the aggregate times the density of water Bulk Density of Aggregate [1]The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a container of a specified unit volume
After the clays have been liberated they must be removed from the frac sand otherwise they can cause serious problems in the dry screening process in terms of both capacity and efficiency To remove the liberated clays the sand exits the attrition cells and reports to a sump where water is added to bring the slurry to the ideal density required to feed a separator or hydrocyclone
