Coarse Aggregate Gradation: Test Sieves or Screen Trays?

April 04, 2021

<div><a href="/blog/coarse-aggregate-gradation"><img loading="lazy" src="/Content/Images/uploaded/blog/2021/April/coarse-aggregate-gradation.jpg" alt="Coarse Aggregate Gradation: Test Sieves or Screen Trays?" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 700px;" /> </a></div><p>Does the particle size analysis of coarse aggregates always require a testing screen with large screen trays? In a situation where larger testing equipment is not available, there may still be ways to get the job done. Using conventional round test sieves for large particle sizes is less efficient, but still acceptable if done properly. We discuss test requirements, sieve capacities, and tips to help with equipment selection.</p>

<div><a href="/blog/streamlining-aggregate-gradation-tests-tips-and-tricks"><img loading="lazy" src="/Content/Images/uploaded/blog/aggregates/streamline-aggregate-tests.jpg" alt="Streamlining Aggregate Gradation Tests: Tips & Tricks" style="display: block; margin-left: auto; margin-right: auto; width: 100%; max-width: 715px;" /> </a></div><p>Sieving for particle size distribution is the primary test requested for construction aggregate samples. Whether field samples are being tested to evaluate a new aggregate source or just coming in as part of day-to-day quality control of production, particle size distribution is a primary consideration. If processing and sieving is not handled efficiently, it creates a backlog.</p>
