aggregate screen sizes chart

The effective size (ES) is defined by the size of screen opening where 90 percent of a sample of granular media is retained on the screen and 10 percent passes through the screen and is referred to as D 10 The larger the grain size the faster the wastewater moves through the sand and the more wastewater that can be filtered Aggregate Screening Solutions | Polydeck Aggregate Screening Technology Since 1978 Polydeck has been helping aggregate producers improve production rates reach specification requirements and extend wear life by providing them with a complete offering of polyurethane and rubber screen media products and systems in a variety of stock and custom designs and sizes

Typical Aggregate Gradations Open-graded aggregate Gap-graded aggregate Uniformly graded aggregate Dense-graded aggregate All of the particles are approximately the same size Very little fine aggregate thus lots of void space between particles Very little aggregate in the medium size range Lots of different particle sizes thus very little void

Overview The gradation and size test (Figure 1) is used to determine aggregate particle size distribution Size distribution is perhaps the single most important aggregate quality associated with the control of HMA mixtures Aggregate gradation and size affect HMA volumetric properties as well as mixture permeability and workability

*A grit size is defined by the distribution of grits retained on a sieve set up that meets the requirements of ANSI Table 2 or 3 The numbers in the two sieve columns in this chart represent the midpoint sieve for the grading of the corresponding grit size

size (or size range) most commonly found in the distribution Less care is taken to denote whether the value is based on volume surface or number so either run the risk of assuming volume basis or check to assure the distribution basis The mode is not as commonly used but can be descriptive in particular if there is more than one

A 4-mesh screen means there are four little square openings across one inch of screen A 100-mesh screen has 100 openings per inch and so on As the number indicating the mesh size increases the size of the openings and thus the size of particles captured by the screen decreases Higher mesh numbers = smaller particle sizes
