Surface Moisture Analyzers - insmart systems

Surface moisture (free moisture) is, as the term implies, water held on the surface of the coal and determined as the loss in weight in an air atmosphere under rigidly controlled conditions of temperature, time and airflow confirming to ASTM D 3302.

DETERMINATION OF SURFACE MOISTURE AND PARTICLE

2020-12-15 · MATLAB. Continuous (online, every 30 minutes) images were taken over a coal bed which was moving on a conveyor belt. It was a challenge to determine the particle size distribution and surface moisture of coal online. The distribution of reflectivity of coal in the image varied according to the moisture content and particle size.

2021-3-5 · The moisture in Coal consists of two parts. One is the moisture held within the molecular structure of the coal called “inherent moisture.” Removal takes place only at temperatures greater than 100 deg C. The second part is the moisture that is on the surface of the coal. This is normally due to the conditions and locations of the mines.
