Screening separates the sand and gravel into different size ranges. Water is sprayed onto the material throughout the screening process. After screening, the sized gravel is transported to stockpiles, storage bins, or, in some cases, to crushers by belt conveyors, bucket elevators, or screw conveyors.
Pressure screening capacity was found to decrease with increasing fibre length, fibre network strength and flocculation. Pressu re screen fibre fractionation sele ctivity was increased by broadening of the fibre length distribution of the feed furnish. The furnish properties also affected the separation selectivity of fibres, sand and gases in the
Preliminary treatment consists of screening, grit removal, septage handling, odor control, and flow equalization. This fact sheet discusses screening and grit removal. Screening Screening is the first unit operation used at wastewater treatment plants (WWTPs). Screening removes objects such as rags, paper, plastics, and

· The fineness of the sand has a bearing on the physical properties that can be developed by the sand system. Procedure - A dry sample of sand is screened through a "nest" of sieves (largest opening sieve on top and progressing down the nest). The sample is shaken for 15 min in the screen shakers, and the sand retained on each screen is weighed.
