Sieve Sizes: and Metric Sizes
Sieve mesh sizes are based on dimensions of the mesh size opening, or on the number of openings per linear inch. The two major standards governing test sieves and appropriate sizes are ASTM E11 and ISO 565/33101, both of which specify parameters for aperture dimensions, mesh size, and statistical variations. Opening sizes and mesh diameters for test sieves are often duplied between these ...

Chapter 4 Engineering Classifiion of Rock Materials
• discrete rock particle size (use D 50 or cube root of the product of its three dimensions) (a) Rock unit identifiion The rock unit is the basic mapping unit for the rock material field classifiion (RMFC) system. It is defined as a body of rock that is identified in the field and mapped according to measurable or otherwise describable physical properties or features at a scale useful ...

Understanding rock and gravel grades and uses | MDI Rock
Minus: This grade can contain up to 80% fines. Screened: This means some of the fines have been sifted out, leaving perhaps 20%–40% fines in the batch. Sized. This grade should have no more than 15% fines. Washed. These rocks are usually a pretty uniform size because they've been washed to remove the fines. Crushed rock costs

How to Class Crushed Rock by Size | eHow
Apr 27, 2018 · Step 4. Compare the average diameter of the stones with the Crushed Stone Sizes chart (see Resources). If you needed to shake the stones through a sieve, your stone size will be classified as "dust" or "sand." If, after shaking, you have a significant amount of dust on the opaque bag and still have gravelsized stones in the sieve, you likely ...
