relative density of coal

Estimation of InSitu and Product Total Moisture ACARP Abstract

Lumps were selected from the raw samples and treated as follows: saturation in water under reduced pressure determination of the relative density, and moisture, of the saturated lumps and determination of a range of coal quality parameters. A survey of the coal industry was carried out, seeking data on the various
