Gradation Types (see Graph) Aggregate gradation can be generally described by a few broadly defined gradation categories; each one describing a general type of gradation. These categories are: Dense or well-graded. Refers to a gradation that is near the FHWA''s 0.45 power curve for maximum density.

A gradation test is performed on a sample of aggregate in a laboratory. A typical sieve analysis involves a nested column of sieves with wire mesh cloth (screen). See the separate Mesh (scale) page for details of sieve sizing.. A representative weighed sample is poured into the top sieve which has the largest screen openings.
We have the testing apparatus you need to perform all aggregate tests. Screen Shakers separate coarse aggregate samples into six or seven size fractions for gradation tests. Gilson Testing Screens, Test-Masters, and Porta-Screens safely process large samples efficiently.

Inconsistent gradation makes it nearly impossible to produce an acceptable asphalt or concrete product. Roads constructed with segregated aggregate have poor structural integrity and shorter life expectancy than those made from properly desegregated products.
Being we one of the biggest sand stone crushing industries in Uttrakhand and Rajastan area Propel''s machines have utilized to yield a maximum productivity of 20,000 to 30,000 tons per day. The Cubical aggregate shape with excellent fines / sand (Zone II) gradation is the unique feature Propel''s crushers.

Perfecting the Performance of Secondary Crushers | E & MJ
In primary-secondary HPGR circuits, the secondary circuit can be closed with a screen to provide a consistent top size and gradation for optimizing HPGR performance. Closed circuited secondary crushing can also bring benefits if cones are used in tertiary crushing, too. However, the cost of the additional equipment is not always welcome.

Apr 16, 2021· The gradation of the feed material should be continuous from the maximum to minimum particle size. Do not allow "holes" in the feed gradation (gap graded material). Use a well graded feed. 3. Keep some material smaller than CSS in feed. Keep up to 15 per cent of feed below the CSS to encourage rock on rock attrition crushing.
Maximum Aggregate Size & Nominal Maximum Aggregate Size
Jan 24, 2013· By the CT 382 definition, the maximum aggregate size is 3/4" and the nominal maximum aggregate size is 1/2". In the November 2011 version of CT 202, nominal maximum aggregate size is defined as "one sieve size larger than the first size to retain more than 10%."
The aggregate continues to the hot elevator by screens to the hot bins. The screens provide the final separation of the aggregate. ... Both the aggregate gradation and the asphalt content are interrelated and equally important. Paving asphalt is really difficult in cold climate. The hot mix cools down faster and harder to compact.
Vibratory Screens. Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification.
