What Is the Bulk Density of Coal? - Reference

Apr 03, 2020  The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. 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.
