Types of tests to determine moisture content of bulk cargo

Particle Size Distribution Analysis:

A full particle size analysis can be performed in a standard dry-sieve tower or using a Malvern Mastersizer wet laser particle analyser for very fine materials such as concentrates.

Static Angle of Repose:

The natural rill angle (angle of repose) of a bulk material sample can be determined for fines and coarse materials.

Dynamic Impact Adhesion & Build-Up: 

At higher velocities, impacting material streams onto wall surfaces can lead to build-up over time.  This test work is aimed at measuring and observing any build-up effects on a wall surface on which material impacts at a pre-set inclination angle and impact velocity.  Performing this test work at one range of wall materials and bulk moisture contents helps in selecting an appropriate wall surface for the desired application.
