What Is the Bulk Density of Coal? | Reference.com
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. It is a mature coal and is very hard and shiny ...

Bulk Density of Coal depends on Size.Grade or Quality and Moisture in Coal. In a laboratory, Bulk Density is measured by filling the Coal in an empty Vessel of size one Metre height,length and breadth. The nett weight of coal gives the bulk densit...
Influence of moisture and particle size on coal …
The coal blend bulk density for coking processes can be adjusted by changes on particle size, i.e., the coal crushing level, or even drying or humidifying the coal, that are easily manipulated in the coal beneficiation. The modification of density in relation to the particle size requires care, since it can fall in a region of high density achieved by larger particles or even in a region with ...

ISO - ISO 23499:2008 - Coal — Determination of …
ISO 23499:2008 provides description of a cone procedure for determining an uncompacted bulk density of crushed coal less than 37 mm in size, such as is charged into coke ovens. It focuses on the uncompacted bulk density of coal resulting from flowing the material into a measuring container (box) in the absence of compacting forces.
