Field Gradation Unit(AGU)

The Field AGU is used to automatically run gradations at aggregate or asphalt plants.

The Field AGU receives a sample from the Automatic Belt Sampler (ABS), shakes the sample, grades the sample, and provides a user with a gradation report (Percent Passing, Percent Cumulative, Percent Retained, and Weights of all Sieves).

Users can analyze gradation data to make changes to the close side setting of their crusher and produce their aggregates closer to specification.

A Sample can be shaken and a report generated in approximately 10 minutes.
