thermal drying coal

What Is the Bulk Density of Coal? |

The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter. It is a mature coal and is very hard and shiny. Bituminous coal has a bulk density of 42 to 57 pounds per cubic feet, or 673 to 913 kilograms per cubic meter.

A study of the influence of thermal drying on physical ...

This study will investigate thermal drying as a feasible solution to effectively remove this moisture. During thermal drying coal is fed into a high temperature environment; this can influence the physical and mechanical properties of the coal. The effects include swelling, caking, cracking, loss of water, loss of volatiles, and many more.
