Screening. What is Screening? Screening is the separation of material into 2 - 6 different sized products. The material is separated by passing it through a vibrating 'screen box' which has a number of different sized screens, or meshes, which the material falls through like a seive.
Open area on a screen, the ratio between the area of the holes and the screen surface, helps to determine the screen capacity. By decreasing the space between holes, webbing or wire diameter, the open area may be increased, increasing capacity.
Fine Aggregate Fine aggregate is that material which passes the 4.75 mm (No. 4) sieve. Fineness Modulus An empirical factor used to measure the fineness (or coarseness) of fine aggregate. The fineness modulus is defined by both CSA and ASTM. A low number indicates a fine sand, a high number a coarse sand. For supply of concrete fine aggregate, it has been found that a Fineness Modulus of ...

Fine aggregates are typically sizes smaller than the #4 sieve. What people refer to as "dust" is typically aggregate smaller than the #200 sieve.
