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

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
